vomits after eating

Question
I have a 6 1/2 month old Chihuahua. Everyday for the last week about 4 hours or so after he eats his meal he starts vomiting.What could be causing this and what can I do to stop it???  

Answer
Hi Frank,

Because your puppy has been vomiting consistently for about a month, it's time to have him examined by your vet.

It's impossible to guess at the cause, because there are many causes of chronic vomiting. The problem may be anything from a food allergy or food intolerance, to a serious condition such as kidney disease.

It would be helpful to the vet if you could report if your puppy was vomiting or regurgitating, they're different actions with different causes. Vomiting is an active process. The pet is apprehensive and heaves and retches to vomit. If food is present in vomit, it is partially digested and a yellow fluid, bile may be present. Regurgitation is fairly passive. The animal lowers its head and food is expelled without effort. The food brought up by regurgitation is usually undigested, may have a tubular shape, and is often covered with a slimy mucus.
Knowing if your puppy is vomiting or regurgitating will help your vet come to a diagnosis.

I hope I've been a help.
Best of luck,

Patti
