Diagnosing Canine Hematuria

Since many reasons could be the reason why your dog has blood in their pee, it pays to take them to the local vet to let them handle the situation. While the possible causes are plenty, your vet should have the necessary knowledge and experience to pinpoint the main cause of your dogs’ hematuria. But how can you help check if your dog’s pee indeed has blood in it?

You can do this by placing a piece of white cloth or paper beneath your dog as they start to urinate. This way, you check if their urine is indeed discolorated. However, the best way is to collect urine samples of your dog’s pee in a clean container and take it immediately to your dog’s vet.

When you’re able to acquire a urine sample, your dog’s vet will start examining the urine. He will also check your dog for other signs and symptoms present. They will inspect your dog’s genitalia as part of the physical exam. 

As for the urine sample, they will use it for urinalysis. Your dog’s vet may order a series of other tests including blood chemistry workup ultrasound, dipstick colorimetric test, and blood pressure measurement. Once they get the results, it will be easier for them to diagnose the reason why your dog’s pee has blood on it. 

Treating Hematuria In Dogs

In order to treat your dog’s hematuria, your dog’s vet will have to check the main cause first. After that, they can start prescribing the best ways to treat hematuria. Usually, you can expect your dog’s vet to advise the following.

  • Prescribe Medication. Depending on your dog’s medical condition, the vet will prescribe a series of medication your dog will have to take to treat hematuria.
  • Special Diet. While under treatment, the vet may advise a new diet to help with the management of the symptoms. 
  • Lifestyle Changes. In some cases, vets will allow and restrict certain activities that your dog can engage in to help with the recovery.
  • Surgery. In extreme cases, your fur baby may need to undergo surgery to treat the cause of your dog’s hematuria.

As a dog owner, it is one of our responsibilities to know the medical history of our fur babies. This will make it easier for veterinarians in diagnosing our pets. If you’re able to acquire the medical history of your dog from its breeder, the shelter, or any previous owner, make sure to bring them along with you at every checkup. This should include your dog’s past medical conditions, diagnostic results, and prescribed medications.

When dogs pee blood, we dog owners can’t help but worry. However, what your dog needs are your empathy and understanding. Along with blood in urine, you may find your dog peeing in places they are not supposed to pee in. What matters the most is you get to understand the main reason behind your dog’s current situation. This way, you can address the issue and help them treat whatever the underlying condition may be.
