Puppy is leaking urine.

Dr. Marie replied:

There are a few things that can cause a puppy to not be able to hold her pee like you have described.

She may have an ectopic ureter. I drew a picture to help explain what an ectopic ureter is:



The normal side is labelled as Kidney #1. The ureter is the tube that takes urine from the kidney to the bladder. Note how on the side of Kidney #1 the ureter empties into the bladder.

But, on Kidney #2, the ureter goes past the bladder and empties into the vagina. If this happens the vagina can't hold urine like the bladder can and so it empties out which results in a dog that leaks urine.

The way that a vet tests for an ectopic ureter is by doing an xray using medication that is injected that allows them to see urine pass from the kidneys, through the ureters and then see where it goes.

Some dogs with an ectopic ureter can be fixed with surgery.

It is also possible that she has a medical problem such as a urinary tract infection or crystals in her urine. Both of these cause inflammation that makes her feel like she has to pee all the time. Your vet can determine this with a urine test.

I hope she is ok!
