mac08 - He is unsure. Gus is following him around and getting in his space, which he isn't a big fan of, but he's tolerating it pretty well so far. Plus, Gus gets to go outside so much more often than he does, which he doesn't like.
katespade I hope the transition is smooth! It's a big adjustment for an older dog, I know our first dog had no idea what to think when we got the second one. He tolerates him fine now though!
mac08 - Did it get better or worse after the first few days? Bowser seems to be hesitant, but okay right now. I'm just worried that he's going to act out in a few days, once he realizes that Gus is here to stay.
katespade I guess better? He really just acted jealous when the other dog got attention, like trying to get in between me and him when I was petting him, lol. Maybe some growling if the new dog had a toy he wanted or something. But mostly he ignored him.
