Why is my dog peeing blood if her urine tests are normal?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 10 months and 6 days old | 45 lbs

My dog has been peeing drops of blood inconsistently. At times she pees a lot. For a while she was drinking a ton of water but not so much anymore. Once and a while she will pee with drops of blood. Sometimes she will attempt to pee more than once outside. I have gotten her urine tested and it all came back normal twice. The vet has done a vaginal check and has checked her anal glands. She said it was all normal but her female anatomy is lower than most dogs. What else can I ask the vet to look?

Blood in the urine is never normal, even if it only occurs intermittently. Likewise, it’s unusual for Tilly to experience so much inconsistency in her urination habits. Some young female dogs can have recessed or hooded vulvas, which can make them more prone to developing urinary tract infections. However, since Tilly’s urine has twice not shown evidence of infection, it sounds as though it’s time to look in a different direction. I would start by asking your vet if they can take x-rays of her abdomen to check for evidence of bladder stones. The crystals associated with bladder stones often show up on a urinalysis (I’m assuming that’s what was done with her urine samples), but not always. If the X-rays are clear, your next step may be an ultrasound of her bladder with a veterinary radiologist to check for any other abnormalities. Bladder tumors can also cause similar signs, although that would be highly unlikely given how young Tilly is. I hope this helps and that you can find some answers soon!

    Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Winnie. Sounds like she needs some imaging studies such as x-ray or ultrasound to try to determine where the bleeding is coming from and what is causing it. Sometimes dogs have occult urinary tract infections meaning their tests look normal but they have the signs of an infection. Maybe she just needs to be treated for a suspected urinary tract infection. Good luck
