More: We got Wolfie 9 months ago from a rescue in the Southern California desert. He was ~8 weeks old. Wolfie is very high energy as most Heelers are - but he is the sweetest and smartest dog I've ever had! He is protective of his house and family, but when someone comes home, he shakes his tail so hard it seems like it'll fall off! Wolfie loves to herd our cats into the house if they sneak out. He really does have the heeler instincts. Wolfie loves riding in the car with the window down and of course he can't wait for an occasional Puppacino!
