history: I felt very happy last night when my new dog was running around playing. I didn't think she knew how to play and would always be stuck to my leg and worried. I felt very happy last night when my new dog was running around playing_comma_ I didn't think she knew how. Yeah_comma_ dogs have to learn how to play.  Kinda funny you don't always consider that.
current: I do, but she was really abused before and was so docile and quiet..some never do learn normal animal behavior..I have rehabilitated many.
next: It depends on how young they are.  I have a rescue that was abused but she was real young.  She snapped out of it.
