My dog felt sick and his
tummy got red. His mouth
also got red and really big. I want to know if this
is something dogs get because they are sick or is there something wrong with him. Also, what can I do when my dog throws up.
This is an unusual symptom. It may be an allergic reaction??? A vet visit will not hurt. If your pet vomits one time, you do not have to worry so much. If your vet continues to vomit then a vet visit is warranted. vetcare
