hi my name is sheila.I have a 4 year half Pomeranian and half Chihuahua and it has been sneezing a lot and today when i walked him he vomited some yellow vomit that looks like foam and it smelt bad and when i came home, he started vomting agin but this time it was white...what should i do....
He has probably just come down with the flu. I would suggest just keep an eye on him, make sure he is drinking water and see how he is eating. If he isn't acting better within 24 hours I would call your vet and get him in to see the Dr.
As a small dog, any persisten vomiting is dangerous as it can rapidly lead to dehydration - take your dog straight to the vets to have him checked out.
