Well, we caved on crating our labradear Sadie, who is 9 years old, when she was a cute little puppy. She ended up keeping me up all night, so I slept during the day. Husband took her to work in the AM with him so I could get some sleep. Now I'm a permanent night owl. The dog interrupts our sleep nightly in a king sized bed by kicking us out of her way, and by dreaming with her legs. This is something I should have been smart enough to avoid, especially with a big dog. We had yorkies before and crated them well. Little dogs are sneaky peeing little basterds, however, and are not to be trusted. Sadie has never gone in the house, not once. A lot of housebreaking success has to do with the season. Summer dogs are easier to house break than winter puppies, IMO. Some people swear "hurry up" holds new meaning when housebreaking a winter puppy, IDK.
All I know is my kids slept in our beds and were OUT by the time they hit 4 years of age, by their choice. This GD dog will be sleeping with us for the rest of her natural life, which will probably end up being 18 years, if our dog history is any indication. My cats lived 18 and 22 years, the yorkies lived 16.5 and 14.5 years each.
