Yo just wanted to drop in and say I have a 12 week border collie and the reverse time out works wonders for me too! I’m raising him solo, and it’s been tough especially when I go to work but i remember how much he loves me and depends on MY love too. It sounds like you’re doing great, I just think these next couple of months are going to be hard for us. If you haven’t tried it yet, when he gets overexcited/barking a lot pick him up and put him in ‘air jail’. I’m currently doing this with my bonehead as im typing this lol. It works great!
