Some people say that my dog is over weight. But she isn't it is just her body type because she is a chiwawa beagle mix! Anyways my dog Lucy has the acceleration of a lawn mower, a squirl with 3 legs could probably out run her. I believe that gravity is what is weighing down on Lucy not the extra cookies. The force of gravity weighing down on Lucy is roughly 10 newtons (Dan Duguay told me). Gravity is not Lucy's friend. Her little legs have a hard time moving on there own. The photo attached is a very slimming photo of Lucy!
