My neighbor had a 200 lbs one named king the other neighbors hated him but I made friends with him and found him to be one of the smartest dogs I've known he guarded my house ...and was fun to play with if you like playing with a polerbear
Funny you said that, when my kids first saw him they both said he looked like a polar bear! He is awesome, we have had several people over today and he loved them all! Have yet to hear him bark, but I bet it will get someone's attention.
