I have a 10-month old male Golden. He's absolutely incredible - so fun, playful, and loving. We are still in the process of training him not to pull on walks - it's definitely a work in progress because of all that puppy energy. He has a normal collar, a chain collar, and a harness that we switch up walking him with. He's still pulling a lot on walks, but SLOWLY getting better. Therefore, I'm afraid of using any type of collar on longer walks because I don't want him constantly pulling with his neck and putting pressure on his throat and trachea. BUT, the current harness we have also seems to put a little bit of pressure on his throat/trachea area as well. I can tell his breathing is a bit more labored when he pulls even on the harness. I've tried having the harness very tight and snug, and that doesn't work. I've tried having the harness really loose, and that also doesn't work. So, I need some recommendations of harnesses and/or collars that are good for a Golden and don't put so much pressure on his throat or trachea. Thanks.
