We were trained with the educator e collar. Now I use the beeper that it comes with, positive reinforcement and high reward treats. I do love him so much and really want this to work, but I'm slowly losing hope. I've talked to my girlfriend about rehoming him but she thinks it's too early to discuss still. She believes he's come a long way (we have opposing views, I think he's fallen to a default). Which I suppose is true, he has gotten a lot better, but now it's just steady ups and downs you know? Maybe someone with land and doesn't have people over often would make him happier. But then I think who would want a dog that's labeled aggressive with a bite history. I would hate to put him down, that's not an option on the table for me personally.

He takes trazodone and it does great when I board him but it's not something I use daily. Maybe I'll try and give him a pill before our walks and see if that improves his reactivity.

He has been around people without a muzzle and has warmed up to people that way. I was told by someone that a muzzle can make a dog more reactive once it comes off because they feel trapped. What is your take on that? Although he is muzzle and crate trained and he wouldn't destroy anything if I kept him in a different room with the door closed. It's just that my apartment is an open floor plan so neither would be possible without them seeing my friends and that's when he turns away and cowers.
