If your dog is fat, you're not getting enough exercise.
It is known that Beagles in general are high energy dogs. Not yippy-yappy high energy but rather need to get lots of exercise.
I take Winnie on a good morning walk everyday and she also gets a walk in the afternoon/evening most days too. After the walks or whenever I think she needs a little fresh air, she also has a tie-out in the back yard that lets her sniff to her heart's content. She really is better behaved during the day and sleeps better at night with regular exercise. Isn't that true for most of us?
Anyway, Nick's new purpose in life is Operation Wear Out Winnie. He is great about talking her on long walks especially on his days off. His newest technique only takes a few laps around the block and is very effective in resulting in a dog snoring on the couch by 7 p.m.
