How often does your pup have to go pee? Buck is 4 months old now and when he is out of his crate he seems to want to be let out every 30-40 mins or so or maybe even more often than that...We were out this weekend riding around in the car and visiting places and he didnt go to the bathroom for 4 hours straight...he wasn't even confined to a crate during this time...so how come when he is out in the house and such he runs to the door to be let out to pee so often?
