pardon my stupidness. but why do people need this. Are you asking because
of what it does. I dont know about this. i guess people dont like the barking so they silents a dog??? Isnt it like declawing a cat. it takes away its little defence? I hate that my dog barks sometimes un -controllable. But I figure its my fault for not knowing how to train him . not his...and we now have a trainer.he also likes to bite(that really pisses me off). does that mean people think his teeth should come out. he also poops in the house sometimes.So we should sew up his little whole? I dont get the fact that dogs are the problem and should be quiet. I think may be people are the problem. I know i'm one of them

sorry
