My first dog was a full size Dachshund, Gus, was free, his family had too many allergies.
My Beagle was from a higher up hunting line, went for 53 bucks in 1965.
His daughter was free
My next dog, a good purebred Lab, was 300 bucks in 1977, and was without a doubt, the unhealthiest one I have ever had.
My Pit/Golden Ret/??? Mix Gus, was free, he was supposed to be $30, but I never paid my vet for him.
Present dogs, Lab/Dobe/Husky? mixes, King and Molly were free.
