Vet-Verified Tips: Urinary Tract Infections in Dogs, Signs, Causes, and Bladder Care

Surprisingly, urinary tract infections (UTIs) impact nearly 14% of dogs throughout their lifetime, making them a common but often overlooked health concern. 

If you think your dog has a UTI, see your veterinarian first. UTIs usually need antibiotics, and the same signs can point to bladder stones or kidney disease.

In this article, we’ll cover the key signs to watch for, common causes, how vets diagnose UTIs, and everyday habits that support a healthy urinary tract.

How Can I Naturally Support My Dog’s Urinary Health?

Everyday habits can support a healthy bladder and urinary tract. They do not replace veterinary care, especially if your dog has trouble urinating, blood in the urine, or pain.

Here are six everyday habits that support a healthy urinary tract:

#1. Cranberries support a healthy bladder lining.

Cranberries are packed with proanthocyanidins, natural compounds studied for how they support a healthy bladder lining. Their polyphenols also support urinary tract health in dogs.

Opt for cranberry supplements instead of juice, as the latter often contains high amounts of sugar. Always check the label to ensure proper dosage and effectiveness.

#2. Apple cider vinegar may support a normal urine pH.

Some pet parents use apple cider vinegar to help maintain a normal urine pH. Ask your veterinarian first, because the right pH depends on your dog’s urine test.

The simplest way to add apple cider vinegar to your dog’s diet is by mixing it into their water. Start with a small amount, about half a teaspoon, to gauge their tolerance. If your dog responds well, you can gradually increase the dosage but do not exceed 1 teaspoon per 50 pounds of body weight.

If your dog starts to have gastrointestinal problems, interrupt adding it to their water or lower the amount.

#3. Good hydration supports a healthy bladder.

Proper hydration and a balanced diet help maintain a healthy microbial environment, supporting urinary tract health. Wet food adds extra water to the diet.

The right diet also supports healthy kidneys, a healthy prostate in male dogs, and a strong immune system. A nutrient-rich, well-balanced diet and adequate hydration are essential for a healthy microbiome. Urinary tract health is closely connected to overall well-being.

#4. Ensure your dog has frequent opportunities to relieve itself.

Frequent bathroom breaks and full bladder emptying support a healthy urinary tract, especially in dogs that have had urinary issues before.

Pet parents can support this by ensuring access to fresh water and offering frequent bathroom breaks. This strategy benefits dogs of all sizes, breeds, genders, and weights.

#5. Enhance your dog’s grooming and maintenance routine.

Improving your dog's grooming and hygiene routine supports urinary tract health. Regular cleaning, especially around the genital area, keeps the area clean and healthy.

Dogs with a hooded vulva (where skin folds partially cover the vulva) are more susceptible to dermatitis, which fosters bacterial growth. In these cases, perivulvar hairs (the technical term for hairs around the vulva) may fold inward, drawing bacteria into the vestibule and increasing the risk of infection.

Although surgery is an option, it can be costly and impractical for some pet owners. As an alternative, regularly cleaning the vulva with antiseptic pet wipes can help maintain hygiene and keep the area clean.

#6. Consider a natural product that supports a healthy bladder.

Zumalka’s URINARY TRACT SUPPORT is a homeopathic spray designed to support a healthy bladder and normal kidney function. It is not a treatment for urinary tract infections. If your dog shows UTI signs, see your veterinarian.

URINARY TRACT SUPPORT contains Berberis 30k, Cantharis 30k, Nitricum Acidum 30k, Pareira Brava 30k, Sarsaparilla 30k, Solidago 30k, and Terebinthina 30k, along with other natural ingredients.

What are the Different Types of Dog Urinary Tract Infections?

Knowing the different types of urinary tract infections (UTIs) in dogs helps you understand what your veterinarian is looking for. Veterinarians generally categorize dog UTIs into two main types: sporadic bacterial cystitis and complicated UTI.

Sporadic bacterial cystitis

Also known as an uncomplicated UTI, this type of urinary tract infection develops in the absence of any anatomical or functional abnormalities.

In other words, it can occur sporadically in an otherwise healthy dog. For instance, if a dog experiences fewer than three episodes of bacterial cystitis within a 12-month period, the condition is classified as an uncomplicated UTI.

Complicated UTI

Recurrent UTIs, also known as complicated bacterial cystitis, often result from an underlying anatomical or functional abnormality. For example, breeds with loose skin, such as Shar-Peis and Mastiffs, may have a hooded vulva, which increases their risk of recurring bacterial UTIs.

Moreover, certain medical conditions can make dogs more susceptible to persistent or recurrent infections and may complicate treatment. Conditions like diabetes, kidney disease, hyperthyroidism, and Cushing's disease are common factors that contribute to these challenges.

What are the Clinical Signs of UTI in Dogs?

Interestingly, one distinguishing aspect of a dog's UTI compared to other canine health issues is its specific signs and symptoms. Below are the key indicators of this condition:

• Straining to urinate (stranguria)
• Crying or vocalizing (indicating pain during urination)
• The presence of blood in the urine (hematuria)
• Urinary incontinence (inability to control urination)
• Dribbling urine
• Frequent urination with little output (pollakiuria)
• Strong-smelling urine
• Excessive licking of the genital area
• Fever

If you observe any of these signs, prompt veterinary care is essential. Left untreated, a dog's UTI can progress and potentially cause more serious health issues.

Dog UTIs vs. Other Health Problems

Here's something many dog parents may not realize: The common symptoms of UTIs can closely resemble those of other health conditions. That’s why consulting a veterinarian is essential when these signs appear.

I strongly recommend bringing a urine sample to your veterinarian for testing to rule out other potential issues, such as diabetes, bladder stones, kidney disease, or even tumors. When it comes to our pets' health and well-being, it's always better to be safe than sorry.

Additionally, it's important to note that UTIs in dogs could often signal an underlying health issue. That’s why identifying the root cause, rather than just the symptoms, should be your top priority when this condition arises.

What are the Causes of Dog UTI?

Canine UTIs are not limited to a specific breed, age, or sex. Many people assume otherwise, but in reality, all dogs can experience this health concern, something many dog owners overlook.

Urinary tract infections (UTIs) in dogs have six main causes: a weakened immune system, certain medications or medical procedures, bacterial infections, anatomical or structural issues, underlying health conditions, and environmental or behavioral factors. Let’s explore each of these in detail.

Weakened immune system

Weakened immune function is common in older and senior dogs, making them more susceptible to illness. Chronic stress and anxiety may also weaken a dog's immune defenses, increasing their risk.

Certain medications or medical procedures

Certain medications and medical procedures can increase the risk of UTIs in dogs. These include long-term use of immunosuppressants or steroids, which weaken the immune response; recent catheterization, which can introduce bacteria into the urinary tract; and recent urinary tract surgery.

Bacterial infections

While Escherichia coli (E. coli) is the most common cause of UTIs in dogs, other bacteria can also lead to infection. These include Mycoplasma spp., Proteus spp., Pseudomonas spp., Staphylococcus spp., Klebsiella spp., and Enterococcus spp., which can enter and infect the urinary tract.

Anatomical or structural issues

The most common anatomical issues leading to UTIs in dogs include a narrowed or blocked urethra, which restricts urine flow and increases the risk of infection, and ectopic ureters, which, due to their abnormal positioning, can make a dog more susceptible to infections. 

In female dogs, skin infections around the vulva, such as perivulvar dermatitis, can allow bacteria to enter the urinary tract.

Underlying health conditions

A dog's UTI may indicate an underlying health condition. Potential causes include bladder stones (urolithiasis), kidney disease, diabetes mellitus, Cushing’s disease (hyperadrenocorticism), urinary incontinence, and, in male dogs, prostate disease.

Environmental or behavioral factors

Common risk factors for UTIs in dogs include exposure to dirty living conditions and inadequate grooming. Holding urine for too long and swimming in contaminated water can also increase the risk.

How is Canine UTI Diagnosed?

Diagnosing a UTI in dogs is typically straightforward. If a vet suspects a UTI in a patient, they first perform a full physical examination. Dogs with urinary tract issues often tense their abdomen during bladder palpation, which is a sign of discomfort.

Symptoms like frequent urination, bloody urine, or crying during urination may prompt this examination. After the exam, veterinarians typically recommend a urinalysis to confirm the infection. Early diagnosis and treatment help prevent complications and protect the pet’s well-being.

Urinalysis

Microscopic analysis of a urine sample is essential for diagnosing UTIs in dogs and cats. Urinalysis detects bacteria, confirming an infection. Additionally, blood in the urine may indicate inflammation or urinary tract injury, while crystal formation can suggest metabolic issues or the potential for bladder stones.

By recognizing these signs, veterinarians can make an accurate diagnosis and prescribe the most effective treatment. Addressing the infection promptly is vital to ensuring the pet’s health and well-being.

Culture and sensitivity testing

When UTIs recur, a veterinarian may conduct a urine culture and sensitivity test to pinpoint the bacteria causing the infection. Repeated infections often signal incomplete treatment or an underlying medical condition.

A sterile urine sample is collected during this test to identify the bacteria present and assess their resistance to antibiotics. This essential analysis helps veterinarians select the most effective treatment, improving the chances of a full recovery.

When Should You See a Vet for a Dog’s UTI?

Take your pet to a veterinarian immediately if you notice any of the following signs:

• Blood in the stool or urine
• Significant loss of appetite
• Vomiting
• Yellow or green discharge from the nose or eyes
• Straining to urinate
• Inability to urinate for 12 hours or more

These symptoms could signal a serious health issue, and delaying treatment may result in life-threatening consequences. Acting quickly by seeking veterinary care can help protect your pet’s health and improve their chances of a full recovery.
