I just went to a groomer because we found ticks all over our little guy & he did NOT like us removing them & even wanted to bite us. When we went to the groomer & I told her he needed a muzzle, she did not want to remove the ticks because she was the only one working & wouldn't be able to hold him down alone. So...she had my buy the Vet-Kem Tickaway Tick Collar & said it would kill the ticks & make them fall off. It was only $5 so I just bought it, but wanted to know if anyone else had used it & what they thought about it.
