My friend has two new puppies. The first is Copper who is only about 4 weeks old. The other one is Trapper who is a little over 3 months. Trapper is to rough to play with Copper right now but they should be good playmates when Copper gets the age Trapper is now. Both are Heelers or Cattle Dogs. Trapper might have something else in him and has a tail. Copper is the tailless kind of Heeler. Trapper and my dog Ziva play well together, chasing each other and playing in the small pool.
