Ive been working with my pup as much as i can but its not every day due to school and work. He has basic obedience down and ive been wanting to move on to something new. I still throw him retrieves with the bumpers every night. But tonight he did the first couple retrieves like normal, but then after those, he didnt go pick them up. Ive always heard that you can bore the dog and i was thinking i might be doing that. Is there anything else i could do to help keep it fun?
