I have an 8 yr old neutered male who weighs 22 lbs. For a while he decided to pee on my couch. I used natures miracle on it and he doesn't do that any more. However, he has blood in his stool. Could this be from his weight? He also is active and playful but lays around a lot.
The blood in the stool is not related to your pets weight. You should have your vet examine your pet and don't forget to bring a stool sample. It may be an intestinal parasite, colitis, dietary, or a mass in the colon or rectum. Good luck, vetcare
