Zoi Has A Boyfriend

Zoi has been driving us crazy over the past week to go outside.  I looked out the window to check on her and saw this...

Who is this dog with Zoi?  I've never seen him/her before.  Bob took some food out for him (yes, he's a him), but he wasn't interested...

He's friendly, groomed, looks like he is definitely a pet, but has no tags.  Never took food, but did take a treat.

He has been coming to visit on a daily basis.  He even came to the back door to see if Zoi could come out and play...

No, don't even think it.  We are not taking him in.  We are not getting another dog.  Zoi will have to play with her new friend when he comes to visit.
