Wait, hode up, hode up, hode up. It's not a choke collar. It's a training collar. Why would you wanna choke the dog? HelloOo.
Here's how you do it. If you walk your dog on your left side, then the training collar should look like a P when you put it on the dog. If you walk your dog on your right side, then, the training collar should look like a q when you put it on. That way it can never bind up and choke him. Really, you should always walk him on your left knee with the P in the front. And just little pops if he gets out front too far, really he shouldn't leave your left knee. Or right knee if you walk him on the right side. When you pop the collar, just a real fast pop, the collar loosens again and gives itself slack, you just want to get his attention to get him back in his spot, not choke him. Walk around the block practicing that one time and he'll never leave your knee again, you'll never even have to pop it. If you;re choking him with the collar, you have it on him backward.
