Maybe a volley ball. Kavi is about 80 lbs I think. He#27&18;s very trim. He was the biggest dog in the pack for a while but his son Remus is much taller and will be much bigger when full grown. Two of his other sons are also bigger than he is now. Two of his ancestors were up in the 160 lb range as adults – that was all muscle and bone. Hagrid, one of them. Was as tall as me when he stood on his hind legs. Kavi is much smaller.
