Hello. I am sorry Zack is having trouble with his feces. Yellow poop is usually a sign of either diarrhea (gastric upset), mal-absorptive disease (German Shephards are prone to getting Exocrine Pancreatic Insufficency "EPI"), or worms. Also, poop colour changes with various diets. If your puppy is not dewormed and is still bright and happy and active, and eating/drinking well, I would start by deworming him. At one month of age he should be transitioning from milk from his mother to solid foods, and this may make the feces a less yellow colour as well. If the feces is very greasy and bad smelling, and if Zack is very thin, then I would be worried about EPI. If your puppy is bright and happy, and eating well, and the diarrhea is solid or soft/solid, then just deworm and start weaning Zack onto a good quality puppy food. If there is diarrhea present or Zack is lethargic I would have him seen by a veterinarian.

    Congrats on your new puppy! This yellow poop can be a sign of intestinal worms, which are very common in puppies. He will need a deworming treatment if he's not up to date on his treatments, and I recommend giving him Panacur. He will need one every two weeks until he is 12 weeks old. Then one every month until he is six months of age, and after that he should be dewormed once every three months.

    the food can be a cause depending on what type and color he is feed. This can also indicate a bacterial infection in the intestines. You can try changing foods or picking up a probiotic from the pet store or vet and add it to the food to see if that helps If it continues or has diarrhea, then he should be checked by your vet.

    Hello. Puppy poo can be a very different color as they age & develop different populations of bacteria in their gut, so the color you are seeing may not be too abnormal. Two weeks of age is also a good time to bring a sample of the poop to your vet for a fecal analysis & start deworming the puppy. As long as the puppy is eating & acting well, I would not be too concerned, but do have the puppy(s) checked for intestinal parasites. Thanks for using Petco Pet Education Center, formerly Petcoach.
