I just want to thank everyone for their suggestions.
We keep our 4 month old puppy in a crate by our bed,
but he kept waking us up at 4 AM in order to
attempt to come on our bed - he wasn't vewry interested
in peeing or pooping at 4AM.
We tried ignoring him, but that didn't work.
The 2 things that worked are: covering the crate
but not completely covered (making sure that there is air getting in)
and shaking an empty Coke can with 7 pennies inside. The Coke can
really did the trick - covering the crate adds about an extra hour of sleep.
We talked to our vet about this and he endorsed the Coke can method
as well as covering the crate.
Tiny now sleeps till 6:30 - 7:00 AM. :-) :-)
