Well, he's almost 7 months old and he is a big dog. It's not like he is a 15 pound puppy that can easily be picked up when I don't want him heading towards something. He is over 60 pounds and very powerful not to mention he is 30 pounds less than what I weigh. He easily pulls me if he is focused on something such as a flying ball or a kid. I just wanted to know what size to get. I wasn't really asking for advice on whether to get one or not. I understand these collars require training just like anything, it can be abused. I wasn't asking about that either. Everyone will have their opinions about what does and does not work but in the end, I am the owner of this dog and I work with him daily. No one else on this board knows how my dog does and does not act or if I work with him or not. I do work with him on walks daily. He is good for the most part but just needs some added correction. Training a dog is not one size fits all. You have to adapt to works best for you and your dog. I am doing this. Trial and error. The Freedom No-Pull Harness worked until he hit 60 pounds, now not so much so on to the next thing. Maybe I won't even like the pinch collar but how will I know until I try it? I appreciate everyone's input but I really wasn't seeking advice on if I should get one or not. I was just asking about the correct size of the collar I should get.
