Breezy,

I am sorry of the loss of your brother. Your dog can sense that you are upset and this may be a part of the vomiting. Are you giving your dog the coated aspirin? I would stop that first and see what happens. Is your dog eating while all of this confusion is going on at your house? If not, that could be a part of the problem too. If the vomiting does not stop in the next day or two at the most, I'd take it to the vet.
