Improving response time
So Echo is very good with his obedience; sit, down, heel, heel/finish, come, place, up, lengthy stays, stays from another room, etc, on leash and off...however...he does it all SO slowly. I can't tell if it's because he's unsure of himself, which I really doubt-- I praise the heck out of him, it's stuff he knows well and we've worked extensively with the trainer on, and he doesn't show any signs of anxiety-- or if he's testing me, or what. How can I get him to respond in a more timely manner? He doesn't hesitate, he just...ambles. Any ideas on what I may be doing wrong/how to encourage a little bit of speed?
