Ok

Well, this product did keep fleas off my dogs back and tail end. Now he has a million covering his head, eyes, ears and it's bad. I scratch them off the best I can, rinse him with warm water and back they go on his head. Ok if you can't afford a Vet's once a month treatment. All flea medicine should be available without a prescription.Can't get rid of them otherwise.
