OK, I'm running into an issue with my bulldog and it's driving me crazy. He's an English bulldog and his lifespan is 8 -10 years. Mine just turned 12 but he has turned into an absolute disaster at night. As soon as it gets dark, he literally just starts barking, and I mean nonstop all night long until it's time for bed. I can give him a treat, or even a new chew toy, but the second he is done with it, he goes right back into a whine/bark that is extremely annoying. I love him but this has been going on for about six months now and it's driving me friggin' nuts. Any input or solutions??
