Sorry your quote didn't post last time.
As I said I'm really uneasy about trying new things on him, I've heard they can get immune or more appropriately the local flea population because the dog's body processes it more flushing it more.
My Scoobers has taken it for over 4 years and Elvis only 2 it is still working for Scoobers though.
