My puppy is pooping blood but acting normal. What should I do?

Hi, my puppy has been bleeding when he poop. I haven’t change his food or give him new treats besides chewing bones to keep him busy. He’s acting normal, he’s eating normal and he’s sleeping normal. I wonder what this could be and how I can treat it? He is 3months old and got all his vaccines up to date.

Wow, that is quite a bit of blood. I suggest you have Elijah examined by a vet. Here are some things that can cause bloody stools: 1. Parvovirus 2. Parasites: the most common parasites that cause blood in the stool are hookworms, whipworms, and roundworms 3. Dietary Indiscretions 4. Hemorrhagic Gastroenteritis 5. Rectal Injuries 6. Rectal polyps 7. Stress Since he is doing otherwise well, my best guess is that he has parasites; even if he has been dewormed. I suggest you have your vet test his feces for parasites. Best wishes.

    Yes, I would be concerned in that blood in the feces isn't normal. Bailey is a young puppy, and the most common cause of blood in the feces at his age is intestinal worms. I would get him a deworming treatment from the vet if he isn't up to date on those treatments. He will need to get a deworming treatment every two weeks until he is three months old, then monthly until he is six months old, and then should get one every three months thereafter.
