If he is sleeping iduring the night, then do a dance :dance: and jump for joy that you arent being woken up for that midnight potty break As long as he isnt going in the crate then you should have no issues.
maverick took to his crate easy too and sleeps through the night but we got him at 14 weeks old. Maverick is quiet in general tho so I still worry about him not going during the nite. maybe were just lucky!
Tyson also sleeps through the night...sometimes we have to wake him up in the morning!! I consider myself lucky. Tyson took to his crate the first night we brought him home, and we have not had one problem yet...keeping fingers crossed!
