Sardius has such a fantastic personality and is so full of life. He loves to play and chase disks & tennis balls. He can jump straight up about 5 feet from a stand, but a 3-foot-high exercise pen will keep him in. Outside he never seems to need a rest but inside he is the first one to lay calmly at my feet while I work. He has sired 4 wonderful litters so far and we are very pleased.
