Hi my brother has a bull terrier, he lives in the state of South Carolina. His name is Biko. Biko has been experiencing constant vomiting over the last few months. Sometimes he can go a week or so and nothing happens. However recently he has vomited twice in a matter of a week. My brother has taken him to the emergency vet. he has had blood work done, x-rays, and some other procedure which involve drinking a white liquid to check for foreign objects. Biko is a well kept dog. So far noting has been found. Biko is such a get pet, he's a year old this week. Our family has grown to love him as if though he belonged to us. We are wondering if all else appears to be normal could it be his food, the environment, digestion ect. We are worried. I want Biko better. What advice can u give. I was told by the Wellness Pet food company to try spreading his food out on a cookie sheet to slow down the eating process. Going to the vet is getting quite expensive and we still don't have answers.
