First some background: Riley got badly scared by a German Shepard (GSD) about six months ago, so has decided that ALL GSDs must be evil and barked/growled at....at all times. He HATES GSD puppies also (they may bite
). We had a Rally class where he was the only small dog with all GSDs!! Let's just say he stayed in a corner away from them and he would snap at them if they tried to come in for a sniff (we're working on that). We've been doing a lot of work with him with his fears. Anyway.....my upstairs neighbor is watching their friends 7 month old HUGE GSD until Sunday. Now Sasha is super sweet, loves people, loves dogs, and is pretty good with little dogs (neighbors have a puggle). Well....Riley HATES her. He's completely turned into a nervous barking growling twit!! We live in an apartment, so there is not too much room to isolate Riley. Except he can hear her from any room in the house, so there is no place to work on a threshold like I usually do.
If sasha goes up/down the stairs (past our door), Riley freaks, running and barking all over the place. He is no better behaved on leash inside, since he is on high alert every second, so paces and woofs and growls. He also is the same (minus the pacing) when being held, and in any room in the house. The same goes for even hearin the GSD bark in her own apartment!!! This has also effected how he is reacting to normal noises since he is on high alert every second now. He woke us up Three times last night going crazy barking at the tiniest things even fans and air purifiers blasting to help keep him calm (and all doors closed).
Any suggestions how to deal with my nervous twit of a dog until Sunday so I don't end up in the looney bin??!! We're trying to manage it (or train, but he's very stressed....). It won't be so bad if I could find a room in the house that he won't react in.

the only other tool (gimmick) I saw was a contraption that dispenses treats to reactive pets. I think I saw it here on this forum. In my world Danny Boy still hates dogs. He acts like he likes them at the vets, doesn't mind seeing them at holidays, but otherwise he barks and goes crazy when he sees them next door or walking down the street or in a car next to his. I would love to know if you find a way to fix this.
I think Danny is getting a bad reputation.
