Your pup is definitely having a reaction to the Frontline. Do you have fleas and ticks in your area or are you being super preventive?
I do not give my girls flea protection at all. The shampoos I use for weekly grooming contail essential oils that are natural flea/tick repellents, as are our conditioning spray we use daily. We haven't had any issues at all.
