The San Francisco SPCA is advising pet guardians to take precautions to prevent their animals from being injured on escalators. The two SF SPCA hospitals, in the Mission and Pacific Heights, regularly receive emergency visits for escalator-related injuries. Dogs' paws can get caught between the moving escalator steps, leading to severe wounds.

"Every month we see far too many escalator-related emergencies," said Dr. Jennifer Scarlett, SF SPCA co-president. "Most of these cases involve small dogs riding escalators at BART stations or shopping malls, but dogs of all sizes are vulnerable. These injuries are very painful and expensive to treat, but the good news is that they're completely preventable."

Dogs who suffer from escalator-related injuries will often lose parts of their toes, and will sometimes need amputation to facilitate healing.

To prevent these injuries, the SF SPCA is advising all pet guardians to carry their dogs on escalators, or use the stairs or elevator. Alternatively, booties should be used to protect your dog's paws. Dog booties can be purchased online or at most pet supply stores.
