Hello,

I'm sorry to hear what your dog went through. It sounds likely that with the overload of food, he developed a food bloat. Basically, the stomach can fill up so much, it has nowhere to go but back up.

It is extremely important for you to do two things: keep him as rested as possible for the next 24 hours so that his stomach doesn't flip and twist on itself, causing a blockage in or out (which requires immediate surgery to save him), and NOT feeding him anything at all for the next 24 hours. We want him to vomit, and I'm glad he did- this got some out, and with the diarrhea, he should be ok to start small amounts of food at a time in a day.

You want to watch him closely the next 24 hours for signs of severe distress: excessive panting, enlarging abdomen (from the gas buildup), lethargy, and no longer able to vomit anything up (though possibly trying, getting saliva up). These are signs an emergency vet would be your best bet.

When you feed after 24 hours, start with only a couple of tsps of a bland diet, like boiled chicken and white rice, to help settle his stomach at that point, and firm up that stool. After a a few hours, offer another 2 tsp. Gradually you can increase the amount until the next day where he can have a normal serving of that bland diet only for 2 or 3 times a day only instead of tiny amts with a few hours in between.

After a couple of days of bland food, gradually switch back to normal diet.

If at any point he is distressed, he will need a vet, and DO keep him as calm and rested (crated if needed) as possible.

Best wishes!
