What causes dog peeing blood?

The scientific term of a dog peeing blood is Hematuria, and it can be caused by several different things. Noticing the blood in dog urine is not always easy. After all, we don’t really stare at our dogs while they are doing their business. However, keeping a close eye on your dog’s urine and feces is somewhat necessary. It can be a clear indication something is wrong with them.

There are situations when noticing blood in dog urine is easier. The dog can pee on a lighter surface like a wall or snow. You can notice urine discoloration, and bloody dog urine can come in different colors. It is usually red, amber, orange, brown, or even normal.

The tricky thing about blood in your dog’s urine is that the urine can sometimes seem completely normal. It can be clear, and the vet will not notice it until they perform a special test. The vet should do a diagnostics test to determine the presence of red blood cells in your dog’s urine. Other health issues can also cause urine discoloration. Make sure you call your vet if you notice anything funny about your dog’s urine.

Most common causes

A dog peeing blood is a broad symptom, and it can indicate a wide range of potential problems your dog can experience. Like diarrhea or vomiting, it can be hard to pinpoint the exact cause based on a single symptom - a dog peeing blood or having bloody urine.

How is the problem diagnosed?

Most dogs are brought to the vet clinic after their owners notice the color of the dog’s urine has changed, and it looks like their dog is peeing blood. That is when vets step in. They are armed with extensive knowledge and experience that helps them diagnose what is exactly bugging the dog.

However, there are some things we as owners can do to help vets in their process. We can take a urine sample and bring it to the vet. If you cannot take it to the vet immediately, store it in the fridge until you can. The other thing we can do is place a white paper towel underneath the dog to make sure there is some urine discoloration.
