Dog Booties are rubber, fabric or plastic coverings for dog's paws, used to protect the animal from cold weather or injury.
They are analogues to human shoes and are most common in sled dog races. The Yukon Quest Sled Dog Race for example requires mushers to carry no fewer than eight booties per dog.
Many dogs are resistant to wearing booties and the velcro straps typically used to secure booties often are inadequate on active dogs.
Changing booties is necessary when they become wet or fly off a dog's paws.
Like shoes booties wear out with use.
Over an extended period of time they need to be replace.
