I have a 1 year 4 month old Morkiepoo. I've been trying to train him on my own but I think we might benefit from a class. I have trained him to sit, stay, shake when a treat is involved but I can't seem to transition him into being motivated without seeing the treat. His leash behavior use to be good but now he's back slid (trying to chase birds, pulling, not listening to me.) He's pushing his limits. His potty training has also suffered. He asks to go outside to pee but not poop. I keep an eye on him but accidents happen. We have a Petsmart and Feeders Supply that I know do classes (in southern indiana). What's your opinion on those, other trainers or should I just continue on my own.
