Poor Jasper! He could have a GI illness, may have eaten something rotten, could have a foreign body, or playing so soon after eating may have upset his stomach and caused him to vomit. He's likely lethargic from feeling poorly. I would try a home remedy to see if that helps him before having to take him into the vet. 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.

    Withhold food for 8 hours and then put him on boiled chicken and rice in small portions every 4 hours. If he keeps vomiting please bring him to the vet in order to get treatment as it might be a gastrointestinal infection that will require medical treatment.

    Poor Chief may have a stomach illness. I can give you a home remedy for him to see if that helps. Withhold food tonight, 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 refuses to eat the bland diet, 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.

    Poor Chance! There could be a couple of reasons why he vomited including a GI illness, eating something rotten, a foreign body, or pancreatitis. I can give you a home remedy for him 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.

    It may be Joy overdid it causing the vomiting. Feed him 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 he refuses to eat the bland diet, 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. I hope this helps!
