Dogs can be prone to urinary problems, and it's essential to understand what's normal and what's not.

The pH level of dog urine can affect their health, with an ideal pH range of 6.5 to 7.5.

Many dogs will have some degree of ketones in their urine, especially if they're not eating enough.

Dogs with kidney disease may have a high concentration of protein in their urine.

Causes and Risk Factors

Urinary issues in dogs are common and can affect dogs of all ages, breeds, and sizes, as well as both male and female dogs.

Some breeds, such as the Shih Tzu, Bichon Frise, and Yorkshire Terrier, are predisposed to urinary stones, which can be complicated by having a urinary tract infection.

Dogs with redundant or excess vulvar tissue may have trapped bacteria near the urethra that can travel upwards and cause an infection.

Female dogs are more susceptible to UTIs due to the shorter length of their urethra, making it easier for bacteria to ascend into their bladder.

Male dogs exhibiting signs of a UTI are more likely to be suffering from another condition, though UTIs are possible.

Here is a list of factors that can increase a dog's risk of developing a urinary tract infection:

  • Female dogs
  • Dogs with redundant or excess vulvar tissue
  • Male dogs with underlying conditions such as chronic kidney disease, neurologic disease, or hormonal diseases
  • Breeds prone to urinary stones, such as the Shih Tzu, Bichon Frise, and Yorkshire Terrier

Who's Most at Risk?

Female dogs are more susceptible to UTIs due to the shorter length of their urethra, allowing bacteria to ascend into their bladder more easily.

Male dogs are less likely to develop a UTI, but if they do, it's often a sign of another underlying condition, such as chronic kidney disease or hormonal diseases.

Dogs with redundant or excess vulvar tissue may have trapped bacteria near the urethra, increasing their risk of developing a UTI.

Breeds like the Shih Tzu, Bichon Frise, and Yorkshire Terrier are predisposed to urinary stones, which can complicate UTIs in these dogs.

Upper Causes

Blood in dog urine can be a concerning sign, but understanding the possible causes can help you feel more in control. Blood in the upper urinary tract is often related to kidney issues.

The kidneys are a vital part of the upper urinary tract, and problems here can cause blood to appear in your dog's urine. Kidney infections are a common cause of blood in the upper urinary tract.

Kidney stones are another possible cause, although they're not as common in dogs as they are in humans. Kidney stones can cause significant pain and discomfort for your dog.

The exact cause of blood in the upper urinary tract often can't be pinpointed, which is why it's called idiopathic renal hematuria. This means that the blood is coming from the kidneys, but no underlying cause can be identified.

Here are some possible causes of blood in the upper urinary tract:

  • Idiopathic renal hematuria
  • Renal telangiectasia (a condition where blood vessels in the kidney widen)
  • Kidney infection
  • Kidney stones
  • Kidney cancer (although this is a rare possibility)

Causes of Issues

Urinary issues in dogs can be caused by a variety of factors, including genetics, diet, and lifestyle. Many urinary issues can be prevented with proper hygiene and weight management.

Infections are a common cause of urinary issues, and can be caused by bacteria, viruses, or other diseases. In fact, bladder infections, or UTIs, are the most common cause of blood in a dog's urine.

Other causes of urinary issues include bladder stones, which can be caused by nutrition, genetics, or persistent infection. Bladder cancer is also a possible cause, although it's not something to jump to conclusions about.

Problems with the bladder and/or urethra can also be a cause of urinary issues. This can include infection, inflammation without infection, and other issues. Some dogs may experience symptoms such as straining to urinate, passing blood in their urine, or having accidents in the house.

Some breeds are more prone to certain urinary issues. For example, Corgis are genetically prone to renal telangiectasia, a condition that can cause blood in their urine.

In addition to these causes, other factors can contribute to urinary issues. These can include long hair or mats around the urogenital area, which can contribute to urinary problems. Diarrhea can also lead to urinary issues, as the rectum and vulva in females are near each other.

Here are some possible causes of urinary issues in dogs:

  • Infection (bacterial, viral, or other)
  • Bladder stones
  • Bladder cancer
  • Problems with the bladder and/or urethra (infection, inflammation, etc.)
  • Genetic predisposition (such as renal telangiectasia in Corgis)
  • Long hair or mats around the urogenital area
  • Diarrhea

It's worth noting that many urinary issues can be resolved with therapy, and your dog can get back to its normal activities.

Symptoms and Diagnosis

If you notice your dog is urinating more frequently or having accidents in the house, it could be a sign of a urinary issue.

Symptoms of urinary issues in dogs can include straining to urinate, urinating small or large volumes, or having blood present in the urine. These symptoms can be tricky to spot, especially in multi-pet households where pets share the same water bowl.

A urinalysis test is often the first step in diagnosing urinary issues in dogs. This test examines your pet's urine, and it's essential to provide a fresh sample.

Other diagnostic tests may include bloodwork, urine culturing, X-rays, or an ultrasound to better evaluate your pet's urinary problem. In some cases, your veterinarian may refer you to an internal medicine specialist for more advanced testing.

Here are some common symptoms of UTIs in dogs:

  • Bloody or cloudy urine
  • Straining or whimpering during urination
  • Accidents in the house
  • Wanting to be let outside more frequently
  • Dribbling urine
  • Licking around the urinary opening
  • Fever

If you suspect your dog has a UTI or is experiencing other urinary issues, it's essential to contact your veterinarian immediately.

If your dog has a UTI, you might notice that they seem uncomfortable trying to relieve themselves or that their urine has a strong smell.

Typically, dogs with a UTI will posture to urinate multiple times, with little to no urine passing.

Bloody or cloudy urine, straining or whimpering during urination, accidents in the house, wanting to be let outside more frequently, dribbling urine, licking around the urinary opening, and fever are all signs of a UTI in dogs.

Here are some common symptoms of a UTI in dogs:

  • Bloody or cloudy urine
  • Straining or whimpering during urination
  • Accidents in the house
  • Wanting to be let outside more frequently
  • Dribbling urine
  • Licking around the urinary opening
  • Fever

These symptoms can vary in severity and may come and go, but if you notice any of these signs, it's essential to take your dog to the vet for proper diagnosis and treatment.

Symptoms and Diagnosis

Symptoms of urinary issues in dogs can be tricky to identify, but there are some common signs to look out for. Dark yellow or amber-colored urine is a clear indication that your dog needs to drink more water or is dehydrated.

Many types of urinary problems have similar symptoms, making it crucial to get a proper diagnosis from your veterinarian. They'll likely order some tests to determine the cause of the issue.

A urinalysis test is usually the first step in diagnosing urinary problems. This test examines your pet's urine for its appearance, concentration, pH, and chemical composition. Fresh urine samples are essential for accurate results.

Your veterinarian may also analyze bloodwork, submit urine for culturing, take X-rays, or use an ultrasound to better evaluate your pet's urinary problem. In some cases, pets may need to be referred to an internal medicine specialist for more advanced testing.

Here are the four main parts of a urinalysis:

  • Assess appearance: color and turbidity (cloudiness).
  • Measure the concentration of the urine.
  • Measure pH (acidity) and analyze the chemical composition of the urine.
  • Examine the cells and solid material present in the urine using a microscope.

Urine samples should be read within 30 minutes of collection. If you collect a urine sample at home, please return it as soon as possible to your veterinary clinic.

Some common issues that can be detected through urinalysis include the presence of sugar in the urine, which may signal diabetes mellitus, and increased turbidity or cloudiness, which can indicate the presence of cells or other solid materials.

Chemical Composition

The chemical composition of urine is a crucial aspect of a pet's overall health. The pH level of urine indicates its acidity, and in healthy pets, it's usually between 6.5 and 7.0.

A pH level that's too acidic (less than 6) or alkaline (greater than 7) can create an environment where bacteria thrive and crystals or stones can form. This can lead to a range of issues, including infections and kidney stones.

Infections

Urinary tract infections are a common cause of blood in dog urine, affecting 14% of dogs and being more frequent in senior dogs, particularly those aged 7 and older.

UTIs can be caused by many different types of bacteria, with E. coli being the most common cause.

Female dogs are more susceptible to UTIs, and underlying health problems can make a dog more prone to recurring infections.

If your dog has a weakened immune system due to illness or a lack of proper nutrition, bacteria are more likely to reproduce and cause infection.

UTIs can be painful and require a prescription medication to resolve, and some dogs may drink more water as a result of the infection.

In some cases, UTIs can be caused by underlying problems such as urinary crystals, stones, or cancers, which may require surgery to resolve.

Antibiotics are often prescribed to treat UTIs, but the specific treatment will depend on the underlying cause of the infection.

If your dog has a UTI, it's essential to monitor their drinking and urinary habits, as some dogs may drink more water or experience straining to urinate.
