We have 3 month old Basenji puppy ( jasper). We've only had him for 3 weeks. The first week, he was really great in in crate at night. It's gotten worse and worse. We always take him out before bed around 11. He started howling at 3:40 am, so I took him out and he did his business. I put him back in his crate and he was howling on and off for the next few hours!!! Help.. We need our sleep.
