Hi,
Our four month old Chesapeake Bay Retriever is very inconsistent with his bladder control. I'm guessing he's just immature (had a Chessie years ago with similar problems), but thought someone would have advice. He keeps his crate dry about half the times he is in overnight. He is developing a few favorite pee spots outside (finally), but he still will not go to the door to try and get outside when he has to pee. He will also not squat to pee inside, but instead will just walk and pee at the same time - almost impossible to see until it's too late. He does the same thing on the outside deck and the patio around the pool. Only when he on grass or dirt will he squat and pee like a typical puppy.
My hunch is that he has developed this "talent" of walking & peeing to avoid getting scolded/caught peeing inside.
We do limit him to small areas of the house (always supervised and not carpeted) and he has had a through physical exam including a check for urinary infections.
Other than that, he is a well behaved puppy and is responding to training with flying colours!
