Humans aren't the only ones fighting obesity.
A British charity called the People's Dispensary for Sick Animals aims to help pets slim down.

Veterinarians are also working with the pet owners on a new regimen to get their furry friends in a healthier state.
The winner of the competition will be announced in September, and the owner will receiving a year's worth of pet food, and a pet-friendly holiday at a Four Seasons hotel.
