I recommend a nylon collar that will grow with your puppy. Once your dog is full grown I recommend a one inch nylon collar with either a buckle or a clip depending how you will be using it. If you will be tying/chaining your dog and they will be close to a fence that they could jump or an object they can get wrapped around I recommend a collar with a clip that can break if they get tangled and they wont strangle themselves.
