Hello I am Devin McAfee and I have a german shepherd and a golden retriever. We walk our dogs together. (So one won't miss the other wile we are walking the other) But are dogs are kind of competitive they both want to be in the front so they pull alot if we don't take the german shepherd the golden retriever is perfect. But are german shepherd wimpers alot without his alpha jaida are golden retriever. So they have to go together jaida it trained enough were she doesn't need any special collar. But are german shepherd is not that trained yet. We tried a gentle leader on him but he wouldn't even move with it on so we had to take it off. I checked other people questions and the answers and all of them said that a harness is not good for a dog. That is what are mom it going to buy but i keep trying to convince here that it does not work. So what collar should i use for my german shepherd.
