I was wondering if she meant a Canaan Dog!!
I have a wonderful Canaan Dog mix named Colby Cheeshead. Canaan Dogs come Israel, where they guard livestock. Canaan's come in black and white and tan and white. The ears are straight-up, the tail should curl at the tip. They weigh around 50 lbs..
The breed is very sweet and loving, very protective of their family. The breed does not get along well with strangers. Most Canaans get along well with other dogs, and they love small kids.
They are very agile and quick, most can clear anything. They are highly trainable, they are very intelligent. Canaans require lots of exercise, and lack of exercise will definitely show (probably on the new couch).
Here's the Cheesedog
. I'll see if I can get a full-body pic. This one looks kind of weird. If you have any more questions, just lemme know!
