Why is my GSD not eating? Is it the new puppy or being unneutered?

Sudden loss of appetite and weight loss in a puppy is very concerning and may be related to fever, infection or a bowel obstruction, particularly if accompanied with nausea or vomiting Please have her assessed urgently by a vet, reduced appetite is never normal in a growing pup

Thanks for using Petco Pet Education Center, formerly Petcoach! As GSDs get older they don't require the same amount of calories as they did when they were a puppy. When this happens, they tend not to eat as often. This breed does not need to eat every meal or even everyday. They usually only eat more when they are working. So if you have a GSD that isn't working (police dog, herding, agility, etc) then he probably won't need to eat as often. Dogs can go long periods of time without eating a meal, unlike humans. As long as Arjun isn't vomiting, having diarrhea, lethargic, or losing weight, I wouldn't worry. Continue to offer his usual food and limit treats to once-twice daily (because they contain more fat than dog food). Kisses to Arjun!

Not eating is typically one of the first signs of illness. It could be caused by a dental problem, systemic illness, infection, or injury. Without seeing Oggy in person, I can't say for certain why she is not eating much. Because this has been going on for 3-4 days, it's time to see the vet. I'd take her into a vet today. Best of luck.

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.

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.

Hello, and thanks for your question about Tyson. It is not normal for a puppy to become so ill and stop eating after a deworming treatment, so I'm concerned there's something else going on. If Tyson hasn't eaten anything in 2 days, he needs to be seen by a vet to determine what's going on.

Thanks for using Petco Pet Education Center, formerly Petcoach! He is adorable! It is not necessarily uncommon for a dog to not want to eat for 1-2 days when adjusting to a new environment. However, that should improve quickly. If he is otherwise fine with a normal activity level, you can continue to monitor for the next 24 hours. If no improvement, have him evaluated by your veterinarian. It could be that he is painful following his surgery. Theoretically, yes, there are things that can be transmitted to your other dogs. Good luck and have a good day!
