thanks and i know...i found it so weird when i heard this scary barking and saw a golden. i was like, "huh?"

okay, yesterday i took mickey for a walk and naturally passed by the neighbors house again. i checked out the body language. his ears were down and tail was wagging. but he was smiling, which i read is like growling because they are baring teeth. they were kinda playing a game or something. mickey and him would bark at eachother and run along the fence. the golden would hide somewhere and mickey would sniff it out. i'm guessing they are playing but then, the golden barks like crazy to get mickey off his territory. *sigh* and what are hackles? lol
