From One Green Planet: "The ad, for Skechers’ GORun line of shoes, reportedly features a French bulldog wearing the company’s shoes to race against a pack of greyhounds. Dog Racing is banned in 38 states and is frequently the subject of cruelty and neglect allegations.
According to PETA Greyhounds used as racers typically live their entire lives in cramped cages and are kept muzzled by their trainers at all times. These gentle dogs are extremely sensitive, yet they rarely know the comfort of a kind word or a gentle touch. When too old, injured, or tired to continue racing, the dogs are often discarded like garbage."
