Why is my unspayed female dog peeing blood, possibly bladder stones?

Updated On September 23rd, 2025

Pet's info: Dog | Pomeranian | Female | unspayed | 9 years and 11 months old | 6.4 lbs

I have a female pomeranian that hasn’t been spayed. She is 8 years old and a bit overweight at 2.9kg (our vet advises that her ideal weight is 2.5kg). She has recently been having small amounts of blood in her urine. She’s done 4 ultrasounds with 4 different doctors and only 1 of them has said that she has bladder stones, and the others said nothing was wrong. She urinates frequently in small amounts and recently peed a deep red pee that smells like blood. Does anyone know what’s wrong?

Thanks for using Petco Pet Education Center, formerly Petcoach! If she has bladder stones, she needs to have them removed because they will irritate the lining of the bladder causing bleeding and other complications. Once the stones are removed, they can have them tested to determine what kind of stones they are and can put Puffy on a special diet to help prevent them from forming again. I would also recommend having her spayed at the same time to prevent a life-threatening infection that can occur within the uterus causing her to need emergency surgery. There is a chance the blood in the urine is coming from her uterus but if a vet saw stones in the bladder, that is more likely. Good luck and kisses to Puffy!
