My dog is vomiting and sleeping a lot. Why is she so sick?
There are many causes for [vomiting](https://www.petcoach.co/dog/condition/vomiting-1/) and lethargy in dogs. Your dog could have a severe GI illness, [pancreatitis](https://www.petcoach.co/dog/condition/canine-pancreatitis), a foreign body causing an [obstruction](https://www.petcoach.co/dog/condition/bowel-obstruction-in-dogs), or may have eaten something rotten. I recommend withhold food for 12-24 hours, and then feeding her a bland diet of boiled white meat chicken and white rice in small amounts for several times a day. After a couple of days of the bland diet, you can slowly add back in her normal diet. If she continues to vomit in the absence of food, vomits the bland diet, stops drinking water and vomiting water, has diarrhea, and/or becomes very lethargic, you need to take her into your vet immediately.
