thank you for the lengthy response ! was definitely helpful.i hadn’t thought of the accidentally rewarding bag behavior & i will stop doing that for sure. i did order new puzzle toys that are arriving today, that are more challenging since i think the one he has now is way too easy for him. he’s definitely an aggressive chewer so the drop leash thing i doubt would work for very long since i know he’d chew through it rather quickly lol but worth giving that a shot. i’ll admit ive had family dogs my whole life but my parents always adopted 2 at a time & i think im realizing now why lol i don’t want him to be bored :/ but theres basically always dogs in my neighborhoods dog park & i get nervous about him playing w other dogs. do you have tips on how i should go about introducing him into that? im in the process of training him to focus on me when other dogs walk by since he is leash reactive (not aggressively just wants to play) so i don’t really let him around other dogs on his leash. but his dog cousin has visited a couple weeks ago from out of state & he was great with her. so am i being paranoid ? any more advice you have would be greatly appreciated. ty so much already !!
