My 1-month-old German Shepherd puppy has yellow poop. Is this normal?
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.
