Classic Jack! The 3 we have now are not classic. Two are long haired, one is longer than your average broken coat, the other one has hair so long that no one thinks he is a JRT. I had him DNA tested and he came out Fox Terrier and Australian Terrier. Both of those were what I expected. The 3rd one looks like a JR in size, body conformation and short hair but his ears stick up like a Fox Terrier. The long haired/broken coat Jacks are not as hyper active as the short haired ones and I should know, we have had about 10 of them in the last 15 years. Four were long haired and 6 were short haired. About half we took as rescues and half we bought.The longer haired variety is definitely my favorite of the two.
