any collar used incorrectly can hurt a dog, dosen't matter how the quality of it is. harness are the worst things to teach a dog not to pull on a leash. they will pull even harder.
I have to say I agree with you 100%.
Prong collars are a very effective training tool when used properly. I have one for my Siberian bitch Luna. She doesn't need it much these days, I usually walk her in a martingale collar.
Anyhow, they are not huge dogs but I think they are feeling a bit left out so here are some pics regardless :lol:
She was yawning in this pic :lol:
Pic overload... sorry.
