Like most pack animals beagles love to sleep in a den where they can burrow. The one on the right has a "roof" over its head and is blissfully asleep. The one on the left is grumbling because he got the short straw.
My mom is definetily (not sure if I spelt that right) an expert beagle mom. (I'm a beagle mom in training!) Beagles are tough and people who don't have a beagle (or a hound in general) just DO not understand!
