So, Sonny is doing okay. Sort of. He's starting to adjust. He's less panicked than he was on Sunday night. He's still jumping at unexpected noises and movements, which we're not expecting to change for a long time; but he's walking closer by me, and allowing me to move about without bolting.
We're still working on the routine, but I think he's house trained. Which, honestly, breaks my heart the most. This poor dog has probably been through hell and back, yet he's house trained. Someone took the time and energy to teach him to do his business outside, but couldn't just plain be nice to him? And, although he's house trained, he's still terrified to go. When he's going, he looks up at me, as if to check to make sure I'm not going to do anything. If I move while he's going, he freezes, stops mid "go." He's been here 3.5 days and has only pooped twice and peed 3 times. He didn't poop for the first day and a half, despite eating all his meals (only when there's no one there to see him or hear him).
He's definitely more scared of Rob than me. It's no fault of Rob's, but he's much taller than I am, has broader shoulders, a deeper voice, and he walks with more purpose than I do. Plus, I'm the one feeding Sonny and taking him for walks, potty breaks, etc.
He absolutely adores Buster. We found out he has giardia, so I'm trying to keep him separate from Roxy and Buster, but sometimes he will just freeze and won't move. I've got a leash on him so I don't have to get close and freak him out, but sometimes it's not enough. So I call Buster over and Sonny immediately perks up, and is likely to follow him. And Buster will go wherever I ask, for the most part. He's been a great helper.
Roxy is none-to-pleased with the whole situation. She's doing okay... the first day was fine, but the last couple of days (prior to knowing about the giardia), Roxy has been raising her hackles when he gets close. He likes to run up to Roxy's face and kiss her, and Roxy's not a fan of that. So I've been doing some body blocking to prevent him from getting too close to her face, and doing a lot of marking and treating for her. She seems to like him, but just not like that he's a total mess.
He's still a huge flight risk, so we are on leash, even in the yard. I think we'll be that way for a long time. He does, however, seem to really enjoy taking walks.
