Why is my 1-year-old GSD not eating his dog food but loves treats?

Updated On September 23rd, 2025

Pet's info: Dog | German Shepherd | Male

My one year old GSD is in his adolescence phase. He has suddenly lost interest in his food. He still loves to have his treats and stuff. He also loves eggs but has totally lost interest in his food food. Why so?

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!

    I would recommend offering a different food altogether and see if Arjun will eat a different food better. Sometimes taste or texture can cause animals to have a finicky appetite. You can also add chicken broth to the current food and see if he will eat the entire amount that way. Adding chicken breast is not a bad idea either but I would try and switch to a completely different dog food. If his appetite declines further, I would recommend having a veterinarian examine him so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
