I never thought about giving oral flea products that way, but reply 66233 from Milissaandcrew is right. “Running pesticides through the bloodstream to get to the skin” does sound dangerous. I always used Frontline Plus before until my dog got Cushings and began losing her hair right where I put it between her shoulder blades. That scared me away from the liquid. Now I’m nervous about the chew. Seems everything we do for our dogs turns out to be against our dogs.
