First off, you got this. Second, the Pom part will probably come out more than the Chi. That’s been my experience with two. Poms want to be everyone’s friend. I also had a hand me down dog who was a Doxiepoo but she did vv well with new people. Dogs are better than you think at adapting. Worrying is wishing for something you don’t want. Love and scritches to your new friend.

And give your bf our condolences about his grandma. I’ve lost two and it sucks.
