So as many of you know since I got kai as a pup I have been very open to learning anything I can about dogs, bully breeds, health, and training. He is now 3 years old and although I'm proud of the commands he knows I know he can do better. He knows the commands focus, sit, down, leave it, speak, stay, and kiss (he will jump up a plant a closed mouth kiss lol). He listens great indoors and his attention is always on me. My biggest room for improvement is his recall. He does great at home but the second we are somewhere and he wants to sniff and pee anywhere his hearing is off even ON leash. On leash he will respond but he will push his limits. Off leash is a different story and his recall is never consistent. I will admit, being my first dogand being that I trained him on my own I didn't work on this as much as I should have.
What can I do to work on his recall and his attention outdoors? I've tried treats but this never worked. Maybe I'm using the wrong kind of treats. I've done research on it and so far I've come across using a long lead and I've also read that an e collar is another method (long lead, low level ecollar. Pressing the button while calling his name and stopping the shock when he responds). I'm not sure how I feel with the ecollar but from the videos I've seen it can work well.
Anyways, any advice is appreciated on how I can work with his recall and focus outdoors.
