I have a 8 month old puppy. at night, when it's time to sleep, i have him go into his kennel. eventually, i would like form him to be able to sleep on his cushioned bed and not in the kennel. he is house trained at this point. he knows that he needs to go outside for potty. i am curious to know at what age did the readers of this question were able to let their dog sleep without being caged.
