Wow that's great! I have done tons and tons of obedience training with Barney and Daisy over the years. Recently, they went back to puppy class at age 9 when Teddy joined us. They absolutely LOVE puppy classes. We've done advanced ones too with clicker training and stuff. Barney is very good at obedience (he even waves on command) as he is so food motivated. Daisy is good too but she gets bored. Teddy...well...he's another story LOL. He does know the COOKIE command very well LOL.
I should mention that we always did off-leash socialization and obedience training.
Well I hope you have a great time with Nick. Here is my secret for teaching your dog anything with reliability....forget treats like hard cookies and break out the tidbits of white meat chicken. I'm talking a tiny shred of chicken is a reward. I had all the puppies in class hanging out with me and all sitting and giving me their paws. All but my little Teddy Bumpkins who was too scared to eat his chicken in class
Oh this is making me want to join up again. Teddy is not too old mentally for puppy class so I think I will!!
