My dog is weak, lethargic, vomiting, not drinking, and eating less. What's wrong?

He should be examined by a vet to determine the cause, especially if he is lethargic. He could have an infection, parasite, pancreatitis, kidney disease, liver disease, endocrine disease, obstruction/foreign body. Your vet can run labwork and take xrays to help diagnose and prescibe medications to treat. He may need fluids to prevent dehydration and medications to control the vomiting.

Poor Logan. He sounds really sick and i am really worried he is getting dehydrated. There are so so many things that can causing the decrease drinking and lethargy like an infection, kidney or liver disease, a toxin, or even cancer and much more. Since he has been since for three days, I would strongly recommend to have your vet or a local emergency vet take a look at him. They will be able to run bloodwork and X-rays if needed to help determine why he isn’t feeling well. They will be able to get him on the appropriate meds to help him feel better. They will also be able to determine his hydration and give him fluids if needed. I hope this helps and he starts to feel better really soon.

Vomiting can be a sign of a number of different problems ranging from minor issues like eating a non-food item from the yard to more serious diseases. Sometimes after vomiting dogs can feel nauseous or weak, so I wouldn't be too concerned about Poochie not responding to his name unless he also seems disoriented or extremely lethargic. If the vomiting continues or he continues to act very abnormal you should see an emergency veterinarian. While it is probably okay to drink a little water I wouldn't encourage him to drink too much as this can sometimes trigger more vomiting.

Hi, and thanks for your question. This is a quite generic but concerning presentation. 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 lasts for more than 24hours.

Not eating, not drinking and being very quiet or lethargic are typical, if unspecific signs of illness. Since this obviously has started a few days ago and is not getting better, I strongly suggest you have Samantha examined by a veterinarian. She will likely need blood work in addition to a hands-on exam to find out what ails her. If she further deteriorates today, take her to a Pet ER today!

I'm sorry to hear that Twinkle hasn't been feeling well today. I would recommend that he is seen by his veterinarian. There may be something on the physical exam that will point to a diagnosis such as joint pain. He may also need laboratory work to determine the cause of this sudden change in him. Encourage him to continue drinking water so he does not become dehydrated. You can offer him food, but stay with his normal diet. Good luck!

Any continued abnormal symptoms (longer than 24 hours) warrants a vet exam. I cannot tell you what is wrong with her just by your description. There are many different things that could be causing her symptoms. Those symptoms are very vague and could be caused by any illness or disease process. I can tell you that you need to be diligent getting weird symptoms checked out especially with an older dog. Please get her a vet exam as soon as you can. They may recommend running some lab tests and/or x-rays.
