This is Alvin not sure what breed he is possibly border collie or healer mix. he is about 50lbs he is good with small children and other dogs not sure on cats but probably not. Not good for livestock or other farm animals he keeps chasing and trying to attack my childrens mini pony. He usually roams free on our farm but lately he has started chasing vehicles going by our house. We havent had the mini pony long but he wont leave her alone hate to keep him chained up all the time. He has just been fixed he is about 1 yr old. He stays outside most of the day unless Im home and its hot he comes in the house at night and sleeps in my room not good to be penned up or left in the house he busted out of our dog kennel and broke it and ate the flooring in the room it was in. He is a good guard dog will alert to anyone or anything in the yard even frogs. We are located in Rolla Kansas he is up to date on shots and just wormed.
