I hear you. My 90 pounds of Golden Retriever thinks he’s a lap dog :)
I have another dog who’s nearly as entitled as the Dane. The humane society I adopted him from said he was half black Lab and half Dane. Turned out differently. He’s actually half American Staffordshire Terrier, a quarter Lab, an eighth Golden, and an eighth Cocker Spaniel. Right now he weighs 90 lb.
