Bobby does this when I put advantage on him. I am not sure what is the problem. the vet said that it may be irritating him. He said to check the skin where you applied to see if it was red. It wasn't. I switched to Frontline for his last dose and it didnt seem to bother him as much. The vet also said that some babies don't like the smell or possibly they have fleas on them that are now moving and dying. |
