My german shepard/ blue heeler mix does this all the time! Lol glad to know I'm not the only one! I always have to bring him in because if not he's like a turkey and sits outside staring up at the lightning and doesn't come in.
It must be! Haha yeah our lab who's supposed to be a water dog hates anything to do with rain, baths, pools or mud puddles but is perfectly content to jump in a dirty river or sewage pipe. Our blue heeler mix adores water and has no problems with baths! I have a question for you: does yours eat EVERYTHING and ANYTHING in its path?
