[QUOTE=Britster;3741892]Midnight-7:45 is not too long. If he is not waking you up, and his crate is dry, then he is telling you he is fine and can hold it!
That's less than 8 hours. Pretty normal night for most pups, though some will take longer and need every 6 hours through the night.

I agree with Brit, if he isn't waking you up and he is dry, he is probably fine. Cody is my big boy, and like Brit's Jackson, he started sleeping all night by 4-5 months. But he was a larger Yorkie, i.e. larger bladder.
Cailee, our newest baby, is 6 months (and 4 pounds) and can make it 6-7 hours (which is great now because she was waking us every 2 hours when we first got her).
So my suggestion is don't worry and enjoy the sleep!
