My dog won't eat her new food, is picky, and looks weak. What's wrong?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Causes of a decrease in appetite are: intestinal parasites, viral or bacterial infection, he ate something gross that is upsetting his stomach, he ate something that is stuck, food allergy/intolerance, Inflammatory Bowel disease, Addison's disease, new treat/food/table food. Sometimes this can be behavioral as well, he is waiting for something better like the Pedigree. If there is not other symptoms like vomiting, diarrhea, or lethargy then that is likely the problem. If you recently got a new bag of his food the company may have changed the formula or there is a issue with that bag of food. If you really don't want to feed him Pedigree then hold your ground. Offer his normal food, you can add water to it to make it more tempting, and if he doesn't eat it then pick it up. Do not offer treats or any other food and then he is not fed again until his next meal time. You can also consider feeding him once daily. If he is otherwise sick, please repost with his symptoms and we will provide advice. I hope this helps and I wish you and Puku the best!

Have her seen by your veterinarian. The odor may be due to periodontal disease that needs to be addressed she may need her teeth cleaned and/or may lose teeth. Severe periodontal disease can be painful which could affect the appetite. Discontinue feeding milk as it can lead to an upset stomach. You can feed her Pedigree if that is all she will eat. Try soaking it with warm water to stimulate the appetite. The "best" food in the world is useless if a pet won't eat it.

Poor girl. I would try some wet food such as Hill's Science diet or Eukanuba as an alternative. You can try mixing it first to try to avoid stomach upset. If she is also acting ill however, she needs to be seen by your vet to have her checked out to determine the underlying issue there. Try giving her some treats for now to make sure her glucose levels stay up. Small soft puppy treats are advised so that she can easily eat them. Best of luck with your fur baby Ruby and I hope she feels better soon! Take care.

Thanks for using Petco Pet Education Center, formerly Petcoach! Loss of appetite can be observed with many conditions such as gastroenteritis, dietary indiscretion, kidney disease, pancreatitis, among many other possibilities. This could also be due to the recent passing of her housemate. I recommend that you continue to monitor Zen for now. If her appetite has not improved in the next 72 hours, I recommend that you have Zen evaluated by your veterinarian for further assessment and treatment. They would be able to check for these possibilities and others depending on the findings on exam. Treatment would be based on findings. Good luck and have a great day! Hoping for a speedy recovery!

Loss of appetite can be observed with many conditions such as gastroenteritis, dietary indiscretion, kidney disease, pancreatitis, among many other possibilities. Her legs may be hurting as well from something like a soft tissue injury or back pain for example which may be causing her to not eat well. I recommend that you have Zoey evaluated by your veterinarian for further assessment and treatment. They would be able to check for these possibilities and others depending on the findings on exam. Treatment would be based on findings. Good luck and have a great day! Hoping for a speedy recovery!

Sometimes puppies can have a slight decrease in appetite when they first come home since it is a big adjustment, however it sounds like you've had her a few days. Given her age and her breed I'd recommend seeing a veterinarian to make sure she doesn't have low blood sugar, parasites, or another medical problem affecting her appetite. If she also seems weak, lethargic or disoriented you should see an emergency veterinarian as soon as possible. She is adorable!

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Koala. It may be she does not like the new food, and that's why she isn't eating it. I would slowly transition her back to her normal food and see if her appetite improves. If it does, then you know it's due to the food. If it doesn't, then it may be a medical illness and I would have her seen by a vet. I hope this helps!
