Thanks for the replies. We have had warmer than thought temperatures, so he as been doing good. Good call on the flap marmilla, I will make one for his house, at least it will keep the dirt out while he is digging. I plan on making a floor for his kennel, maybe he won't find another water line... One good thing about the digging and play time when I get home, he gets tired and is sleeping by 8:00 at night. I have thought about the gates for the kitchen, but they wouldn't hold him, he's got a lot of energy, imagine that from a Heeler, LOL. Any other help about this breed is welcome.
