Well for my Bentley he has a kennel in the bedroom. Of course he's only about 10 weeks and he just came home with me on Saturday morning so roaming is just not an option. His breeder said she had been kennel training him before I got him. First night he protested for about 5-10 minutes(I know he was missing mommy) but then settled into his bed for the night. Last night he whimpered for less than a minute and then settled down and watched me get ready for bed and even talk on the phone without making a peep. I do keep a furry pal in his bed. When he gets bored during the night he plays for a little and then off to sleep again. As a matter of fact I woke up around 1 this morning to his little play growls. Was so cute. The off to sleep again he went. He is learning when the bedroom light is out it's time for bed and he won't be let out again until the bedroom light turns on in the morning. I figure my girls and I don't roam at night so he needs to learn the same habit.
