I think the problem is your greed as regards use of the bed. LOL
The one that sleeps with me, when my daughter visits with her two, is glued to me. Then if I get up to go to the bathroom, she slides over and gets dead center of the area I just vacated. She is 67 pounds. When I get back and try to move her, she goes completely limp, dead weight. It would be pretty funny were it not the middle of the night. /chuckle
This one is only 85 pounds, half Pit and half Black Lab. Worst of all, when he finally passes, there’s a 110 lb. Great Dane anxiously waiting to take his place. Pray for me. They’re both horribly spoiled.
