What is comfortis? I have three small dogs and the stuff you put on the back of their necks makes them sick for 3 or 4 days. My vet said it is poisoning them and not use it on a dog under 16 lbs. I am using flea collars and they are working. We don't have fleas, never have, but ticks are very bad this year.
