I have two German Shorthaired Pointers 21 months old dogs.
They are both trained to sleep in their crate at night.
I put them in their crates at about midnight and I take them out at about 6:30 AM. The male urinate in his crate everynight, the female once in awhile.
They are both very educated in the house and in the backyard during the day.
Any suggestion to prevent this bad habit?
