It is a 5 star rating as far as I'm concerned...the dog next door is a very aggressive husky..he has tried biting me numerous times,,and has bitten many neighbors...he I'd always penned up, and never gets walked...I go out with the special treat, (JUMBO BONE), and now he sees me coming with one, and is leary,.. but I tell him "EASY, NICEEEE, and he gently takes it from me...the neighbors are stunned,,,and I tell them he absolutely "melts", when he sees me coming with one!!! They are THAT GOOD!!!
