Definitely could be a reaction to the flea shampoo or contact dermatitis from a chemical he is being exposed to on your carpet, floors or grass.
If it is just the feet he is licking it is usually a food allergy. Does the food you are feeding contain corn? If so try switching to a food with no corn. Most food allergies are to the protein in their food so if your food has chicken, switch to a different protein source like lamb that he hasn't been fed and his body hasn't created an allergy against.
I would also put pure aloe vera on his feet to try to keep him from licking them. It is safe to lick, but has a bitter taste. |
