My dog hasn't eaten all day. Should I be worried if my dog won't eat?

This is a quite generic but concerning sign. 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 inappetence last for more than 24hours. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! His current anorexia is likely why he has not been defecating. Anorexia for 3 days is concerning given the possible diseases that could be causing it such as pancreatitis, foreign body ingestion, inflammatory diseases, infectious diseases and even cancer, especially in an older dog. I highly recommend that you have Batista evaluated by your veterinarian for further assessment of this. Diagnostic tests are likely to include bloodwork and abdominal radiographs though other tests may be recommended based on the physical examination findings. You may try to offer Batista a palatable diet including things like boiled chicken, ground beef and white rice to entice his appetite though it is extremely important to figure out what is causing it to be able to help him. Keep water available at all times to prevent dehydration. Good luck with your boy! Will keep my fingers crossed for a speedy recovery!

Not eating or more than just a day is definitely concerning, particularly if this is highly unusual and she's turning away things like chicken. I would be concerned about some sort of infectious or inflammatory process going on, a primary or secondary gastrointestinal issue, or one of her organ systems (liver or kidney) acting up in some fashion. If she also isn't taking anything to drink, I would definitely be worrying about dehydration setting in. If she hasn't taken anything for you by the morning, get her into the veterinarian for a check up. Unless they are able to make a determination which is obvious based on physical exam, they will want to likely run some diagnostic blood work and perhaps imaging. Hope this makes sense.

Unfortunately, those are very general signs of illness that can be a part of a lot of different issues. Parasites, illness, obstructions, infections, etc can all be potential causes behind vomiting and refusal to eat. If she's only vomited once or twice, you can try a bland meal of boiled rice and chicken to try and settle her stomach, however if she keeps vomiting, is refusing all food, is very lethargic, or seems painful or in distress, it is best to seek veterinary care ASAP.
