Why is my senior dog peeing blood and has bloody facial bumps?

Updated On September 23rd, 2025

Hello, this is our 13 year old dog. She’s a mix. She’s been having these small bumps on her face for a little while. We’ve took her to the vet to see what’s going on, but they said it’s no big deal. However, when i got her back from a pet hotel(my parents have been out of town for a week), the bumps were bigger and one of them had blood on. Also, she urinates tiny drops of blood-mixed pee. I’m not sure what exactly is going on. Are these part of aging? Or from temporary stress?

I would recommend to take your pup in for a visit with her veterinarian. The blood in the urine is concerning for a urinary tract infection or crystals in the urine. Other things that are less common but can cause blood in the urine are bladder stones, masses in the bladder, vaginitis or a bleeding disorder. Stress will not cause blood in the urine. While she is there, make sure to point out the changes in the masses. Sometimes benign masses can become infected or inflamed, especially if she was rubbing at them. If the doctor is concerned with a more sinister cause, she may recommend sampling the masses to determine what exactly they are. She may also recommend treatment to decrease inflammation. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach.
