My chi has been eating Wellness food for 2 years with no problems. Today though, after she has eaten about 30 minutes to an hour she has been throwing up her food. My first thought is maybe it's a bad bag of food, but she's been eating this bag of food for about 2 weeks with no problems. She is acting very normal. She's not sluggish at all. In fact as I'm typing this she is running around chewing her toy! She has also drinking water with no problems. I don't know what's going on. Maybe her stomach is upset and the food is aggravating it? Any suggestions to what's causing vomitting after eating ? I would like to add that Buttercup only eats Wellness food and carrots for treats I do plan on calling the vet tomorrow.
