RE: squirrel dogs
My Arkansas cousin uses Rat Terriers that he raises for "fun". He does not have what some might call high-dollar blood line stiff, but everyone I have ever hunted behind will absolutely wear us out. He has two now . "Girl" and "Bosco" that hunt great.
Don't laugh ... my squirrel do is a Dachshund ... named Tex! He's a superb treeing dog (and a better blood trailer) and a slow walker, like me !! Problem is he is 13 and I'm guessing not many season, if even this next one left.
