I phoned a breeder about a puppy but it had been sold, she has offered me a 7yr old black and tan female who has always been an outdoor dog. She said she has never gotten pregnant when they tried to mate her in the past, she now wants to cut back on her numbers. She says that she is a friendly, happy girl that loves to give kisses. My main worry would be house training a 7yr old, has anyone here done this? Is it near impossible to train a dog of this age?
