i was always told its their age in months +1 hour. i read it in a little puppy book i got a few weeks ago when i got my puppy. but i have had dogs in the past so im not new to this and my g/f is a vet-tech

is the puppy crate trained? are you pulling her water? is the crate too big?

if the crate is too big, the puppy will pee in one corner and lay in another.
