My 3-month GSD puppy won't eat and is losing weight. What's wrong?

It is possible that Cookie has not hit a growth spurt yet and will increase her growth rate in another month or so. I would recommend a good deworming to make sure parasites are not a reason for slow growth. Also, I would make sure she has a good balanced puppy food. If she does not seem to like the puppy food you can always change the brand or even mix in wet food to help stimulate her appetite. Some shepherds are born with congenital defects but these are pretty rare. IF you feel she is not improving I would recommend taking her to your vet for a good exam.

Losing weight fast is usually a sign of a serious medical condition, unfortunately this is also a very general symptom, you will need to take him to the vet to get it checked first, he will need to have a blood test and xray/ultrasound done to start with.

Dogs are carnivores and therefore should eat non-veg food, preferably commercial complete puppy food for large dogs or specifically for German Shepherd dogs. Try a proper dog food. If he still does not eat you need to schedule an appointment with your veterinarian for an exam as he may be getting ill.

German Shepherds are lanky dogs, especially when they are puppies. Make sure you are feeding him enough and that he is dewormed regularly. If Boe is still abnormaly thin as an adult, then I would worry about something else going on. I would recommend to feed the Royal Canin German Shepherd Puppy Formula. This is a nice diet with the right calories for a growing puppy. Please post again if you have any further questions!

It is normal for dogs to lose their puppy teeth and only see half of the tooth because the root will be gone when the tooth falls out. The canine teeth are the last teeth to be lost and normally should fall out by around 6 months of age in a GSD, so it sounds like Sweety is right on schedule. However, loss of appetite and diarrhea are not normal signs when they are losing teeth, so I would recommend having a veterinarian examine her to determine what might be going on with that. Good luck! I hope that was helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.

I am sorry to hear that your dog isn’t feeling well. Many different problems can cause the signs your are seeing. These include Addison’s disease, kidney disease, inflammatory bowel disease, and exocrine pancreatic Insufficiency , and even cancer. EPI is common in shepherds and this could certainly happen in young dogs. Ideally an examination and blood work should be done by a veterinarian for a diagnosis. If that is the problem then adding pancreatic enzymes such as Prozyme and feeding a bland diet such as hills i/d can make a big difference. Best of luck and I hope you get an answer soon.

Hi, and thanks for your question. This is a quite generic but concerning presentation. Differentials are many, from gastrointestinal diseases (infection/inflammations often dietary related) to any disease that can spread systemically (causing lethargy for example) like infection, and anything that can cause pain/discomfort. The approach must be logic, starting from offering different kind of food. A check up is needed if complete inappetence lasts for more than 24hours.
