Yes, This happened to me aswell, My dog buck came home and my other dog Jefe wouldnt hang around anyone else, But the reason he does this is, Well, You know how popular it is where Kids get sad because a new Baby came home. Its just like that matter, Leave the dog be for awhile and he'll start to act like his normal self.

Yeah i love Pet talk, Ive gotten so much help from it now, And so much help from it on my previous pet talk name that i dont have anymore Anyway, Good luck.

Hopefully your doggy feels better soon!
