RE: wat type of dog
You know, any dog with a good prey drive will tree squirrels. Two of my sled dogs are two of the best squirrel dogs I've ever used. I have a buddy who's Heeler X Border Collie will tree squirrels all day long if you let her. A fiesty mutt will get the job done. I bet if you went to the shelter you will find some terrier or cowdog mix that will be a best pal and great squirrel dog. Be patient on gun breaking. With my two guy's I started taking them out with an air rifle, then the .22 and finally a .410. No problems.
