My active dog won't eat but seems fine. Should I get blood tests?

Updated On September 23rd, 2025

Pet's info: Dog | Maltese | Female | spayed | 10 months and 5 days old | 9 lbs

My dog is very lively, active and happy. She rolls into her back for tummy rubs and loves going for walks. BUT, she has all but given up eating. All her favourite foods are now being ignored. She is drinking fine and going to toilet. She chases her ball like crazy and gallops around the field. She just not eat. She has been like for 3 days. Went to the vet on Friday and they said she seemed fine. No temp and a nice soft tummy. Do I send her for blood tests? Could there be a serious issue? Thanks

Thank you for submitting your question regarding Frynse. Is she eating anything at all? For example, will she eat treats or people food, but just not her dog food? In this case, she could be getting picky and holding out for tastier treats. If she is not eating at all though, this is worrisome. She is a small dog and her blood sugar can drop too low of she goes extended periods without food. It is always a good idea to check blood work to ensure there is not an underlying disease causing her change in appetite. I hope this information helps!

    Hi and thanks for posting on Petco Pet Education Center, formerly Petcoach! It is always concerning when a pet stops eating or has a decreased appetite or interest in eating the foods and treats they normally enjoyed eating. There can be lots of causes for this- anything from dental problems to metabolic conditions can cause lack of appetite. A good oral exam can rule out potential dental problems (such as a tooth fracture). If the physical exam was normal, you may want to consider running a basic blood panel to look for other more systemic causes. I hope this helps!
