Why is my new 5-month-old puppy having diarrhea and accidents?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Female | unspayed | 20 lbs

Hello I got my 5 month old lab mix puppy yesterday and since the beginning he has had diarrhea. So far it's happened inside 3 times and in his crate once. I take him outside and he pees but doesn't poop. Then we come inside and he does. He is eating pretty good. I don't know if it's the food or nervous I feed him purina puppy chow

We can have diarrhea due to stress (of a move to new home) or diet changes, however in young dogs we also worry about intestinal parasites (both worms and Protozoa that aren't killed by deworming) and in some cases depending on vaccine status parvovirus. For this reason it is best to have your pup checked at the vet and bring a stool sample for them to test. Until then you can pick up a probiotic for dogs at the vet or pet store and try feeding plain cooked white rice and boiled shredded chicken breast for a day or two.

    Hudson is most likely having a combination of issues. She could be stressed/nervous due to being with a new family. If you have switched her food that can cause diarrhea and parasites can too! I recommend deworming her and starting a probiotic if the diarrhea is not resolving I would take her to a vet.
