A friend of mine has one.He is a cool little dog with some heart,my apbt was about 3months or so at the time,and the jack Russell was 1 year old and man they got the fur flying ...lol my pup always slept well after a day with that jack. He is was a ball of fire ,unfortunately I had to stop bringing him over for fear of my dog getting a little rough. I wouldn't want anything to happen to the little russell.
