My dog is lethargic and won't eat for days. What could be wrong?

It sounds as Julie is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking her to the vet the first chance you get, she will need to be checked first, if the vet thinks it's a simple gastrointestinal infection she will need an anti nausea injection, antibiotics and a special food for a few days in order to get better. if the vet thinks it is more serious she will need a blood test and possibly an ultrasound in order to find out what is wrong.

I would be concerned that Bell hasn't returned to normal after 12-24 hours. While heat injury is possible usually dogs have issues sooner than now such as seizures, diarrhea, bruising and/or collapse. She could have a problem with her GI tract, something stuck in her esophagus or even a respiratory issues causing her changes. If she continues to cough, seems lethargic/lack of energy, or has any vomiting, diarrhea or continues to have a decreased appetite today she needs to be seen by a veterinarian. I would try calling your veterinarian today as they sometimes have an oncall service or an emergency veterinarian on call to answer questions as well.

Poor Zoey. There are so many things that can cause weight loss, lack of appetite and lethragy like an infection, parasites, liver or kidney disease, a pyometra (infection if the uterus), cancer, and much more. I would have you vet take a look at her. Your vet will be able to do blood work and possible x-rays if needed. They will be able to get her started on the proper treatment plan to help her feel better. I hope this helps!

From the sign you are describing it is quite difficult to determine the underlying problem. General signs of lethargy could be commonly due to high temperature which may be related to an infection. In puppies gastrointestinal and urinary tract infections are by far the most common type of infections. If the signs do not resolve in the next 24hours or if Luna is showing any inappetence, more evident lethargy or any other signs (vomiting and diarrhoea for example) I would strongly advice a veterinary check up.

Poor Mazy! It definitely sounds like something isn't right. There are many different things that could cause decreased appetite and lethargy, so it's hard to say what might be wrong without being able to examine her and run some tests. She could have anything from liver or kidney disease, to heart disease, arthritis pain, a GI problem of some kind, or even some type of cancer. I would recommend taking Mazy to the vet for an exam when you are able to. He/she can do blood work and x-rays if needed to help diagnose the problem and get her started on appropriate treatment depending on what is found.

This is abnormal behavior for sure. If you are worried you should have to the vet for an exam. If you don't think your vet is helpful there is no issue with you getting a second opinion elsewhere. Arthritis, even very advanced, is not likely to cause inappetence. Something else must be underlying. I would suggest a thorough vet exam, some blood testing and some x-rays.

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. It is not possible to help her at home without knowing what she has. I recommend that you have Loki 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!
