and I'm afraid he's going to pull out of his collar.
If he refuses to budge so what! He will eventually budge and when he does, you just praise the heck out of him and give him a treat! He will think he did the greatest thing on earth (and for you he just did!). In positive training you only reward the behavior you want and just ignore the behavior you don't. Later you will learn to associate a sound that ques the dog he just did what you wanted.

Food for thought! Why choke the dog if you can accomplish the same result without it? Don't worry about doing everything because of class. Just do the best you can, have fun and everything else will fall in place. Just enjoy your pup and this time together. They grow soooooo fast and are only puppies once!
