I bought a Buddy Belt for Hulk originally. We did puppy obedience with that, but when we moved into intermediate and started working more on leash work, my trainer suggessted the sense-ation harness for Hulk. She said that the Buddy Belt was challenging for him because it "pulls" in all kinds of places, and mainly under the "armpit" so it can be confusing for the dog. Hulk's focus is not the greatest (work in progress), so I figured anything could help with that. So many harnesses..ha!
Anyhow, we bought the mini size of the sense-ation and have been using it for a few weeks now. He walks really well beside us, very little pulling ahead. Mind you, if he sees birds etc etc, he will go ahead, but I find it's much easier to teach the concept of heeling and loose leash walking. It's also easier to get him to focus on us as well.
She suggested the Sense-ation over other similar concepts because of his size....he's just about 3lbs now. I'm very happy with it, so I'd recommend it as a useful training tool
