Have owned a dozen dogs of different breeds over the last 30 years.
Crate training is, to me, an essential part of dog ownership. I see that some folks are very cautious about time in crate when young. Probably too conservative, but better that than to crate too long. We never had much of an issue, because we've always had multiple dogs. When the new pup comes home, he's got the pack all day, then he goes in the crate at midnight. Most make it through the night pretty soon after. Maybe having other dogs around made a difference. Don't know. Regarding dogs in bed . . . eh. We've had Great Danes and Chihuahuas in bed. Don't really like it. Never lasted more than a few days.
My wife was an ER nurse. Had one man come in with a broken femur. They had a female GSD that slept with them. Guy came back from the bathroom one night and the dog had the wife pinned down and was growling at her neck. Broke his femur tackling the dog off.
Of about 12 dogs, only had 1 that we could never crate train. A reverse brindle boxer. Great looking dog. Great family dog. But had MASSIVE separation anxiety and absolutely loathed his crate. He was born with hyperactive personality. Hard to describe how high strung Chief was. The dog got out one night when my FIL was watching the house. Ended up shot with bird shot through the back of the legs because the local cops thought he was a pit bull. That dog ended up with no teeth because he would chew at the crate or kennel wire when he was in. Hated to see it, but he would wreck the house if he was out. Once, when we let him out, he got into the bathroom where the kitty liter was. Got home, couldn't find him. Turned out he accidentally locked himself in the bathroom trying to get to the kitty treats behind the door. No lights on. In his panic he broke the toilet off the floor and ripped all the clam shell trim off of the door jam. When I opened the door, his entire frothy head was coated with clumping cat liter and he looked like some sort of oatmeal monster dog.
