My vaccinated dog is vomiting, not eating. Can he get sick from another dog?
As long as your dog has all his vaccines and they are kept up to date, he won't get deadly diseases such as parvo, distemper, or rabies from your mother's dog. There could be another reason why your dog isn't eating or drinking, and has thrown up. He could have a GI illness, may have eaten something rotten, could have a foreign body, or could have pancreatitis among other causes. Given that he has drank water and if it's stayed down, I can give you a home remedy to try to see if that helps. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the vomiting continues in the absence of food, he vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away. Best of luck, I hope this helps!
