... full of energy with very alert ears. He seemed fine this morning when I went to work. I didn't get home until 8:00 p.m. due to places i had to be. The puppy was acting scared to death. At first I thought it might be the heavy storms that went through. I don't think so. He had little piles of spit throw up all over the house. His little legs are giving a constant shakey jerk all over. He looks very sad. His ears are laid back. Not normal behavior at all. I fixed him a wiener, but he wouldn't even touch it. There is an emergency vet I could take him to tonight for a high price, or is this a normal reaction to the comfortis and i should just wait and take him to his regular vet in the morning? I read some horrifying stories online about deaths after comfortis. What should i do? He's about 1 and a half years old. D. Stanley
