my 3yr old boxer

Question
my boyfriend has moved in with me and suddenly my 3 yr old boxer acts scared of him when he try to take him out to potty, but other wise loves him plays with him whines for him.... scared to the point that he urinates.... this only happens when im away.... and we just moved to a new place... but he has taken him to potty before we moved and he was fine... and i know my boyfriend has never hurt him in any way!

Answer
It's because of a new place and the change. Dogs have to have routine and security. When amajor change occurs they become anxious and insecure.

He moved in suddenly and you moved-- that's major.

Both practice taking him out to potty together to show him it is alright- then gradually whean him off to just your boyfriend taking him out.
