Yes most definitely. I have noticed that since i put the harness on my dog she is much more calm. She doesn't pull as much as she did with a standard collar. She likes the confront of it. When i take it off of her she tugs at it until i put it back on her lol.
I notice my dog does like it better. He doesn'nt really pull a lot unless he see's a a goose or cat when we're out for walks. So I'm guessing its less strain on his neck, which I'm sure he appreciates.
