Today we picked up our wonderful 12-week beagle puppy, Rigby. He is such a joy and an affectionate pup. My wife and I thought we were doing a decent job taking him out to pee (about 2-3 times an hour). He barely pees outside. He started getting it towards the end of the day. However, once he gets in his crate, he pees inside of it. After he peed in the crate, we washed the mat that goes inside the crate, but it back in, and he peed in the crate again! What do you think we are doing wrong?
