I love the versatility of this comb. I can use it for fleas, dirt, hair, all of it goes bye. The dog loves me combing him out as it isnt sharp and it doesnt pull. It is comfortable to hold. There is two different sizes. I like to use the smaller one for my cat. He gets lots of bells and this combs them out and what cant be it pulls out easily without irritating him. A definite must have for any pet owner.
