by training, what do you mean exactly? i just bought the premier gentle leader in the petite size ($19.99 at petsmart)... it's a collar that goes around the head to prevent pulling on the leash, jumping on people or other dogs, and more control over your pup. the dog can still open his mouth to pant, eat/drink, etc. it is not a muzzle.
Kash is about 3 -3.5 lbs and it fits him perfectly... and i'm sure it could go smaller... the only thing is that Kash continuously tries to get it off when i put it on him. i know it's not hurting him... i just think he's not used to having something wrapped around his nose. i'm hoping he'll get used to it. he's about 6.5 months old and never had anything around his head, so it'll take some repitition to get him used to it... otherwise, i'll just return it to the store...
anyway, i hope that's the kind of product you were talking about.
