I own a 50lb greyhound/boxer mix who is fairly well behaved and in training to conquer the few things she struggles with (greeting people calmly). However, one issue we can’t seem to conquer is what seems to be her boredom. During the day she just lays around and sleeps a lot, but around 7:00pm she tends to get very wound up. Whines a lot, obviously wants us to play, and barks at us if we won’t play with her. However, when we play catch or anything else she gets quickly bored with it and wants something else. By the time she wants to move around (evening) we’re already exhauseted from the day. Any ideas on what we can do around the house to keep her occupied, or on how to make her more active during the day when we can play?
