This collar gets an extremely rare 5 Hank heads just for coming up with a great idea...
The check choke is similar to a martingale collar in that it is a limited choke BUT, when you want to give the dog or pup a correction, the chain part makes an aversive noise. Just great. I mean that. Check chokes are good for young puppies because they are less harsh, and besides that, you shouldn't put a regular choke chain on a puppy that's less than 4 months old. Lastly, THEY ARE CHEAP! By cheap I mean inexpensive. thedogsoutfitter.com has them for, like, $3. If you get one of these, make sure you take it off your dog when you are no able to supervise, and never allow the dog to wear it in his crate. They can catch onto something and panick, ending up hurting themselves. This holds true with any collar.
