Why is my new puppy pooping green? Is green puppy stool normal?

These signs could be compatible with an infective gastroenteritis and, considering his very young age, I would recommend to have him checked as diet correction and specific treatment based on antibiotics may be needed.

It could be due to the change in diet. If he otherwise seems fine than continue with the milk replacer and monitor him. Have him examined by a vet if you have any concerns. He will need to be dewormed with a broad spectrum dewormer and vaccinated once he is old enough.

At five weeks you can start transitioning to a puppy food that is moistened with some KMR or other replacer milk, or look for puppy mousse (Royal Canin and a few other companies carry it) that is designed for transition from milk to solid foods. Otherwise, keeping him eating and drinking can also help, as can testing for parasites or other illness and deworming if the stool does not return to normal.

It is most likely due to the food change. Puppies can also have intestinal parasites, so it is always recommended to have a stool sample checked on Kylo. Your veterinarian can also give medication to help resolve the stool quicker and easier. They also can dispense a bland diet to help resolve it. Then you can gradually transfer her back onto the food she did well with. Thank you for using Petco Pet Education Center, formerly Petcoach.

Stool can change color based on what a dog has eaten. Button may have gotten into something in the yard or snatched some people food or had his diet changed. There are some less likely metabolic issues that can cause very green stool but in the absence of other signs I would not be too worried about this. As long as Buttons is acting normal and his stools are formed (not runny or soft) I would not worry.

Unfortunately a diagnosis can’t be made on stool color alone. Testing for intestinal parasite, liver disease, and issues with intestinal absorption would be warranted. Barley and cottage cheese don’t make up a completely balanced diet, and the lack of certain minerals in the diet can lead to stool color changes. Once your vet has a better idea of what may be going in internally, they can recommend a special diet or have you consult a nutritionist to formulate a balanced homemade diet.

From the photo you provided, it looks like Mishti has quite a bit of grass and plant material in her stool, causing a greenish color. As long as Mishti is acting normal with no sign of vomiting or decreased appetite, this is within the range of normal. Many dogs like to eat grass, and it's only a sign of a problem if there are other GI symptoms present, such as vomiting, weight loss, or decreased appetite.
