My 1 yr old red heeler loves playing fetch more than I love anything. I've seen those automated ball tossing toys for dogs (e.g., iFetch, GoDoGo) and wonder if he'd enjoy one. Does anyone's heeler enjoy playing with these sorts of toys? They can be a little pricey, so my only concern is that he'll only want to play fetch with me (which on one level is endearing) and ignore the ball launching toy. I'd appreciate any insights others can offer. Thanks in advance!
