After watching all 3 of Yogi's videos I just have to say that my girls are still retarded puppies. And mine do not sit so quietly in their crate while I work with the other one.
Lillie is super mellow and sweet, I got lucky with that one for sure!
Yogi and I, though, have worked so much together it's hardly a fair comparison to your pups, and he's 3 years old... Since I adopted him in March 2014, we've taken obedience 1-3, a therapy dog class, beginners and advanced rally, an acting class, 5 sessions of nosework, a trieball class and a shed hunting class. There might have been a couple weeks here and there between sessions when we didn't have a class, but other than that we have never stopped working since I brought him home.
You and the pups will get there, it just takes time!
