What is Prostate Disease in Dogs?

What is it?

Prostate disease in dogs refers to any condition that affects the prostate gland, which is located near the urinary bladder and produces seminal fluid. Prostate disease can range from benign enlargement to inflammation and infection, and can lead to a range of urinary and reproductive symptoms. Prostate disease can affect male dogs of any age or breed, but is more commonly seen in older dogs.

How is it Treated?

The treatment of prostate disease in dogs depends on the type and severity of the condition. In mild cases, medication and supportive care may be recommended to manage symptoms and prevent complications. More severe cases may require surgical intervention, such as castration, to remove or reduce the size of the prostate gland.

Introduction

It had been a few weeks since John noticed that his loyal German Shepherd, Zeus, was having difficulty urinating and seemed to be in pain. At first, he attributed it to the occasional upset stomach or a minor infection. However, as the symptoms persisted, John grew increasingly worried about his best friend’s health. He decided to schedule an appointment with the veterinarian to get to the bottom of the issue. After a thorough examination, the veterinarian informed John that Zeus was suffering from prostate disease, a condition that John had never heard of before.

Prostate disease in dogs is a prevalent condition affecting older male dogs, with about half of the intact male dogs experiencing prostate issues by the time they reach middle age. The prostate gland, located at the base of the bladder and surrounding the urethra, produces prostatic fluid that helps keep sperm healthy and strong. Unfortunately, many owners may not realize their dog has prostate cancer until after the dog’s passing. In addition, unneutered dogs are more likely to develop testicular cancer than neutered dogs.

Types of Prostate Disease in Dogs

There are four main types of prostate diseases in dogs:

Prostatitis

Prostatitis refers to inflammation of the prostate gland, which can be acute or chronic. It is often caused by bacterial infections resulting from urinary tract infections or other underlying health issues. Symptoms of prostatitis include fever, pain in the hindquarters, difficulty urinating, blood in the urine, and lethargy.

Benign Prostatic Hyperplasia (BPH)

BPH is dogs’ most common prostate disease, particularly in older, unneutered male dogs. It involves the non-cancerous enlargement of the prostate gland, which is often hormone-related. BPH can cause difficulty in urination and defecation, blood in the urine, and straining during bowel movements. It can also lead to urinary tract infections.

Prostate Cancer

Prostate cancer is less common in dogs than BPH but can be aggressive and life-threatening. Symptoms of prostate cancer may include difficulty urinating, blood in the urine, straining during bowel movements, weight loss, and lethargy. Unfortunately, by the time the cancer is detected, it may have already spread to other body parts. 

Some breeds are more prone to developing prostate cancer than others. For example, German Shepherd Dog, Golden Retriever, Labrador Retriever, Boxer, Poodle, Doberman Pinscher, Rottweiler, Bull Terrier, Chow Chow, Cocker Spaniel, Dalmatian, English Springer Spaniel, French Bulldog, Great Dane, Irish Setter, Jack Russell Terrier, Keeshond, Maltese, Miniature Schnauzer, Pug, Shih Tzu, Standard Poodles, Yorkshire Terrier, and Vizsla are some of the most commonly affected breeds.

Prostatic Cysts

Prostatic cysts are fluid-filled sacs within the prostate gland. These cysts can vary in size and may cause symptoms like difficulty urinating, blood in the urine, and pain in the hindquarters. In some cases, prostatic cysts may become infected, leading to prostatitis.

When the prostate enlarges due to age or injury, dogs with prostate issues may experience urinary tract infections (UTIs), painful urination, and incontinence. In addition, the prostate is painful for the affected dog, and a prostatic cyst may develop. Prostate-specific arginine esterase, an enzyme involved in prostatic fluid production, may also be affected.

It is essential to monitor your dog’s health, mainly if they are an unneutered male or belongs to a breed predisposed to prostate issues. Regular check-ups with a veterinarian can help detect and address any problems early on, improving the quality of life for your canine companion.

What Causes Prostate Disease in Dogs

Various factors, including age, hormones, and infections, can cause prostate disease in dogs. The most common prostate diseases in dogs are benign prostatic hyperplasia (BPH), prostatitis, and prostate cancer. Here’s how each of these factors can contribute to prostate disease in dogs:

Inflammation of the Prostate Gland

Prostatic disease in dogs is primarily caused by inflammation of the prostate gland. This inflammation occurs when immune cells called macrophages infiltrate the prostate tissue and release chemicals that damage healthy cells. Damaged cells then attract other immune cells, leading to further harm to the prostate, such as prostatic infections. This type of inflammation is common in older male dogs and giant breeds.

What Causes Prostate Disease in Dogs

Bacteria

The second most prevalent cause of prostatic disease in dogs is bacteria. Bacteria can enter through the urethra and cause an infection. Proteus Vulgaris is the most common type of bacteria responsible for prostate infections. Other bacteria contributing to prostate infections include P. aeruginosa, Klebsiella spp., Pasteurella multocida, Streptococcus mutans, and Escherichia coli.

Age and Hormones

As male dogs age, the levels of testosterone can cause the prostate gland to enlarge, leading to benign prostatic hyperplasia (BPH). BPH is a non-cancerous prostate gland enlargement that can cause discomfort, difficulty urinating, and other issues. Neutering can help prevent or reduce the symptoms of BPH, as it reduces testosterone levels.

Prostate Cancer

Prostate cancer is less common in dogs than BPH or prostatitis but can be a severe and aggressive disease. The exact cause of prostate cancer in dogs is poorly understood, but genetic factors, hormones, and environmental factors may contribute to its development. However, prostate cancer can cause symptoms similar to BPH and prostatitis, making it essential to consult a veterinarian for proper diagnosis and treatment.

Cysts and Abscesses

Fluid-filled cysts can form within the prostate gland, causing enlargement and discomfort. In addition, these cysts can sometimes become infected, leading to the formation of abscesses. Abscesses are pockets of pus within the prostate, which can be painful and potentially life-threatening if left untreated. Treatment for cysts and abscesses typically involves antibiotics and surgical intervention to drain the abscess and remove the infected tissue in severe cases.

Congenital Abnormalities

Some dogs may be born with structural abnormalities in the prostate gland, predisposing them to developing prostate disease. These congenital issues may include malformations, improper growth of the prostate, or blockages within the gland. Treatment for congenital abnormalities usually depends on the severity of the condition and may involve surgery to correct the issue.

Trauma

Physical injuries to the pelvic region can cause damage to the prostate gland, leading to inflammation, bleeding, and possible infection. Traumatic injuries may result from accidents, falls, or blunt force. Treatment for trauma-induced prostate issues will depend on the severity of the injury and may involve pain management, antibiotics, or surgery.

Immune-mediated disorders

In some cases, the dog’s immune system may mistakenly target the prostate gland, leading to inflammation and dysfunction. Immune-mediated disorders can be challenging to diagnose and treat, often requiring immunosuppressive medications to manage the condition.

Hormonal imbalances

Conditions that cause hormonal imbalances, such as hypothyroidism or Cushing’s disease, can contribute to prostate disease in dogs. Hormonal imbalances can change the prostate gland’s structure and function, predisposing dogs to developing prostate problems. Treating the underlying hormonal condition can help alleviate the symptoms associated with prostate disease.

Symptoms of Canine Prostate Disease

The initial symptom of canine prostate disease is often a behavior change. A dog’s routine might suddenly appear unusual or even problematic. Prostate cancer is rare in dogs, but when present, it is typically malignant and can be fatal. For example, your dog may start barking at nothing, sleeping excessively, eating less than usual, or displaying aggression toward family members. They might also show an unusual interest in another animal (such as a cat) or spend excessive time playing alone.

Other symptoms of prostate disease in dogs can vary depending on the underlying cause and the severity of the condition. Common symptoms include:

  1. Blood in urine or semen
  2. Straining or difficulty urinating
  3. Frequent urination, often in small amounts
  4. Pain while urinating
  5. Constipation or difficulty passing stool
  6. Ribbon-like, thin stools
  7. Lethargy and weakness
  8. Pain or discomfort in the hindquarters or abdomen
  9. Stiff or abnormal gait
  10. Swelling in the abdominal area
  11. Fever (in cases of infection)
  12. Loss of appetite and weight loss
  13. Vomiting and diarrhea (less common)

Diagnosing Prostate Disease in Dogs

Your vet may be able to determine whether your dog has a prostatic infection or cancer in the prostate through various diagnostic methods.

Physical Examination

The first step in diagnosing is to perform a physical examination. Evaluation of the prostate includes checking the size and shape of the testicles, looking for signs of an enlarged prostate gland or lymph nodes, examining the penis, assessing the anal glands, and palpating the prostate gland. If prostatic neoplasia or abnormalities are detected, further tests should be conducted.

Digital Rectal Exam

If the results from the physical exam revealed no abnormalities, the next step would be a digital rectal exam. This involves examining the prostate by inserting a gloved, lubricated finger into the dog’s rectum and pressing it around the prostate gland. The veterinarian will then recheck the gland.

Blood Test

A complete blood count (CBC) is a blood test that measures the number of white and red blood cells, hemoglobin, and platelets. It can also detect certain toxins in your dog’s bloodstream levels. This test is performed to check for any abnormalities or signs of illness.

Urinalysis

Urinalysis, typically conducted by a clinical toxicologist, can help identify the presence of drugs and other toxins in the urine. This test may also aid in diagnosing a prostatic abscess or infection.

Biopsy

A biopsy of the prostate tissue may be necessary to confirm the presence of cancer, which can be done using fine-needle aspiration. Another PSA test measures the Prostatic Specific Antigen (PSA) in the dog’s serum. High levels of PSA indicate prostate cancer, but low levels do not necessarily rule it out. Therefore, the veterinarian must consider several factors, such as the state of the urinary bladder, veterinary internal medicine history, and blood in the stool or semen, before making a final determination.

Treatment Options for Canine Prostate Disease

The treatment of prostate cancer in dogs is done through surgery, radiation therapy, chemotherapy, hormonal therapy, immunotherapy, targeted therapy, cryosurgery, laser therapy, brachytherapy, and watchful waiting.

Surgery

Each option has its benefits and drawbacks. For example, surgery is often recommended because it is less invasive than other treatments. However, it is expensive and requires anesthesia. In addition, it involves removing the entire gland from the body. This is usually done when no evidence of metastasis (spread) outside the gland exists. Therefore, surgery is often combined with hormone treatments.

Hormone Treatments

Hormone treatments include medications called luteinizing hormones or LHs, which stimulate testosterone production. These medications come in various forms, including injections, pills, and creams. Some men may also need surgery to remove their testicles and have a tube passed through the incision into the scrotum to inject the LHs.

Radiation Therapy

Radiation therapy uses X-rays to kill cells. This is one of the main methods used to treat prostate cancer. There are different types of radiotherapy: External beam radiotherapy and Intraoperative radiotherapy.

External beam radiotherapy uses energy directed at the tumor from outside the body. Intraoperative radiotherapy uses a particular machine during surgery to deliver radiation directly to the prostate gland.

Chemotherapy

Chemotherapy drugs are sometimes given before or after surgery. They can be taken orally or intravenously. Oral chemotherapy is given by mouth. Standard oral chemotherapies include doxorubicin, ifosfamide, and bleomycin. Oral chemotherapy can be taken with or without food. Intravenous chemotherapy is delivered through a vein into the bloodstream. Standard intravenous chemotherapies include vincristine, cisplatin, and etoposide. Intravenous chemotherapy can be taken with or without food.

Immunotherapy

Immunotherapy is another type of drug therapy. It works by stimulating the immune system to attack tumor cells. Monoclonal antibodies are injected into patients. They attach themselves to proteins on the surfaces of cancer cells. Other monoclonal antibodies target the receptors on cancer cells. A vaccine containing antigens found on prostate cancer cells is also used. Vaccination triggers the patient’s immune system to produce antibodies against the antigen.

Targeted Therapy

Targeted therapy is similar to chemotherapy except that it targets specific molecules on the surface of tumor cells. Antibodies bind to specific proteins on the surface of cancer cells—small molecules known as tyrosine kinase inhibitors block the action of enzymes involved in cell division. Tyrosine kinases are enzymes that transfer chemical groups onto other proteins.

Cryosurgery

Cryosurgery freezes the tissue around the tumor to destroy it. Laser therapy uses light waves to heat the area around the tumor. These treatments are very effective in the control of most types of cancer. However, there is always a small risk that the tumor will return.

Brachytherapy

Brachytherapy uses radioactive material placed directly into the tumor. It delivers radiation directly to the prostate via catheters inserted into the urethra.

Watchful waiting means doing nothing until symptoms appear. When your pet has an illness, it may need to be ready to wait. This means doing something once the symptoms appear. Watchful waiting is often used when it is unclear if a pet has an illness or is just emerging for the first time.

Other ways to treat Prostate cancer include interstitial implants, medication, and hormonal therapy.

Interstitial implants use needles to place radioactive seeds inside the prostate gland.

Drugs such as cisplatin, carboplatin, cyclophosphamide, etoposide, doxorubicin, gemcitabine, mitoxantrone, paclitaxel, docetaxel, topotecan, vincristine, vinorelbine, irinotecan, flutamide, leuprolide, goserelin acetate, bicalutamide, cyproterone acetate, estramustine phosphate sodium, diethylstilbestrol diphosphate, and prednisolone are used. Some of these drugs work by damaging DNA in cancer cells. Others block cell growth or stop them from dividing. Still, others prevent blood flow to tumors.

Hormonal therapy is another way to treat advanced prostate cancer. Medications like abiraterone acetate, enzalutamide, ketoconazole, letrozole, megestrol acetate, medroxyprogesterone acetate, nafarelin, nilutamide, octreotide acetate, oxandrolone, tamoxifen citrate, triptoreline, and zoledronic acid are used. Hormonal therapy blocks the effects of male sex hormones. They help reduce the amount of testosterone produced by the testicles. Testosterone stimulates prostate cancer cells to grow.

How to Prevent Prostate Disease in Dogs

How to Prevent Prostate Disease in Dogs

Preventing prostate disease in dogs is essential to maintain your pet’s overall health. Although there are no guaranteed prevention methods, there are several measures you can take to reduce your dog’s risk of developing prostate disease.

  1. Neutering: Neutering male dogs, especially young dogs, can significantly reduce the risk of developing prostate disease, including benign prostatic hyperplasia (BPH) and prostatitis.
  2. Regular veterinary check-ups: Regular veterinarian visits can help detect prostate issues early, allowing for prompt treatment and management. This is particularly important for older, unneutered male dogs at a higher risk of developing prostate problems.
  3. Monitoring for symptoms: Keep an eye on your dog’s behavior and monitor for any signs of prostate issues, such as difficulty urinating, bloody urine, or discomfort during defecation. If you notice any of these symptoms, consult your veterinarian.
  4. Maintain a healthy weight: Obesity can exacerbate specific prostate issues. Ensuring your dog maintains a healthy weight through proper diet and exercise can help reduce the risk of prostate disease.
  5. Prevent infections: In some cases, bacterial infections can cause prostatitis. To help prevent infections, maintain a clean environment for your dog, and ensure they have access to clean water.
  6. Good hygiene: Practice good hygiene for your dog, including regular grooming and cleaning of their living area, to help minimize the risk of infections that could lead to prostate issues.
  7. High-quality diet: Feeding your dog a balanced and high-quality diet will support overall health and well-being, which can contribute to a lower risk of prostate disease.

By following these preventive measures, pet owners can help reduce the risk of their dogs developing prostate disease. If you have concerns about your dog’s prostate health or notice any symptoms, consult your veterinarian for proper diagnosis and treatment.

Frequently Asked Questions

The average lifespan of a dog who was diagnosed with prostate cancer is eight years. So if you were to take your dog to the veterinary right now, he would likely still be alive. However, this doesn’t mean that your dog will always be around. There’s a chance that your dog could die from prostate cancer at any point during his life.

This means that even though your dog might look healthy today, he could develop another health problem tomorrow. That’s why keeping up with regular checkups, including blood tests and ultrasounds, is essential. In addition, if your dog develops symptoms like weight loss, frequent urination, or trouble sleeping, get him checked out immediately.

  • Home Remedy 1: Apple Cider Vinegar (ACV)

Apple cider vinegar contains acetic acid, which helps in reducing the swelling of the prostate. Mix one tablespoon of apple cider vinegar with half a cup of water and drink twice daily. This remedy should be continued for at least two months before you decide whether it worked. If you notice improvement after two weeks, continue taking it for another month.

  • Home Remedy 2: Garlic

Garlic is very effective in treating urinary tract infections. Boil three garlic cloves in a glass of water for 10 minutes. Strain out the liquid and add honey to make a paste. Apply this mixture directly onto the affected area. Repeat this process every day until the pain subsides.

  • Home Remedy 3: Ginger

Ginger is known for its anti-inflammatory properties. So if you want to reduce the swelling of the prostate, take a piece of ginger root and crush it into small pieces. Add these crushed pieces to a bowl containing boiling water. Let it steep for 15 minutes. Strain out and cool down the solution. Drink this tea once per day.

The cost depends on your dog’s age, what kind of surgery you want, and where you live. For example, if your dog is under one year old, it might only cost $50-$100. But if your dog is older than ten, it could cost up to $1,000.

The price varies depending on whether your dog needs general or local anesthesia. General anesthesia means that your dog will be asleep during the entire procedure. Local anesthesia means that your dog won’t feel any pain at all.

If your dog has surgery done because of cancer, the cost will depend on the type of cancer your dog has. For example, cancers like lymphoma, leukemia, and mast cell tumors require chemotherapy before removal. This treatment usually costs around $2,500 per month.

Other types of cancers don’t require this treatment. They include benign tumors such as lipomas, hemangiomas, fibromas, granulomas, and cysts. Benign tumors do not spread to other organs. However, they can grow large enough to cause problems. In these cases, cancer can be surgically removed without chemotherapy.

Cysts and abscesses are two different types of diseases that affect the prostate gland. They are very similar in appearance, so they often need clarification. However, there are some differences between them. The main difference is that cysts are fluid-filled sacs, while abscesses are pus-filled cavities. Both of these conditions can occur inside the prostate gland.

The most common periprostatic cyst is Benign Prostatic Hyperplasia (BPH). This condition causes swelling of the prostate gland. BPH usually occurs when the prostate becomes enlarged due to age. It can cause problems such as difficulty urinating, frequent urination, pain during ejaculation, and lower back pain. In severe cases, BPH can lead to bladder stones, kidney damage, and even death.

An abscess is caused by bacteria growing in the body. An abscess is usually located near a joint or muscle. If left untreated, an abscess could spread throughout your body. Symptoms include fever, chills, redness around the infection’s area, and extreme discomfort.

There is no cure for prostatitis in dogs, but there are treatments that can help relieve symptoms. For example, a veterinarian may prescribe medication to reduce inflammation and pain or recommend physical therapy to improve the range of motion. Surgery may also be necessary if the infection is severe or recurring.

Prostatitis can last anywhere from a few days to up to several weeks, though the average duration is about two weeks.

There is no definitive answer to this question, as the best remedy for a dog with prostatitis will depend on the individual dog’s symptoms and medical history. However, some potential treatments include antibiotics, pain relief medications, supplements such as glucosamine or omega-3 fatty acids, and drinking plenty of fluids.

Prostatitis is common in dogs, but the severity and course vary greatly. It can be a relatively mild condition that clears up with antibiotics or may become more severe and require surgery.

There are several ways to know if your dog has prostatitis. First, if your pet has difficulty urinating, he may have the condition. Prostatitis caused by bacteria can often result in a high fever and poor appetite, while prostate inflammation due to viruses results in reduced mobility of the bladder and urethra (the tube that carries urine from the bladder out). Your veterinarian can perform several diagnostic tests to determine which type of prostatitis your pet has, including blood work and an ultrasound examination of the pelvic area.

If your dog has blood in his urine, an enlarged prostate might be the cause. Other signs of an enlarged prostate include difficulty breathing and coughing, weight loss, vomiting and diarrhea, low energy levels, and stiffness or pain when urinating.

There is no one-size-fits-all answer to this question, as the best treatment plan for an enlarged prostate will vary depending on the dog’s specific health conditions and overall well-being. However, some general suggestions include providing plenty of calcium and protein in the dog’s diet, using supplements such as cranberry extracts or omega fatty acids; and using herbs or other natural remedies to improve urinary tract health.

In general, an enlarged prostate in a dog is not considered severe. The exception to this rule would be if the enlarged prostate was causing difficulty urinating or if the animal experienced other health issues due to the enlarged prostate. If your dog experiences any problems with their enlarged prostate, please consult your veterinarian.

Some possible causes of prostate issues in dogs include hormonal imbalances, lifestyle choices (such as obesity or poor diet), tumors, inflammation, and infections. Further investigation into these factors may be necessary to determine a specific cause.

Prostate cancer spreads quickly and can spread to other parts of the body.

The prognosis for prostate disease in dogs is generally favorable, with most cases resolving without any permanent damage. However, some patients may require surgery to remove the prostate gland. In most cases, dogs will resume their normal activities and live relatively healthy lives after being treated for prostate disease.

There are many possible causes of enlarged prostate in dogs. The most common is benign prostatic hyperplasia, an increase in the prostate gland’s size and number of cells. Other causes include: -Prostate cancer (malignant tumors) -This is a severe condition that can lead to death if left untreated. Therefore, it’s essential to be sure your dog has been screened for this before changing its diet or lifestyle.

The prostate is on the left side of a dog’s abdominal cavity, just below the bladder.

Prostate enlargement may be caused by various factors, including benign prostatic hyperplasia (BPH), prostate cancer, and other medical conditions.

Regular vets can do a blood test/ biopsy etc., if they feel it is necessary, but specialists may be more experienced in doing these tests and should be consulted first.

There are a few diseases that can affect a dog’s prostate. These include prostatitis, prostatic cancer, and adenocarcinoma (a malignant prostate tumor).
