My dog is vomiting, lethargic, shaking, not eating, and has diarrhea?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered | 20 lbs

Chihuahua-boxer mix: he vomited last night but was really energetic like normal. Today, he's lethargic and is shaking as if he's cold, yet his body feels really warm. His ears and paws are cooler. He's not eating much at all. All he wants to do is sleep. He wont even lick at my face like usual. He has really runny poop. Any idea what could be wrong?

It sounds as your pet 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 Buster to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.
