Physical Danger
Pet sitters enjoy (or endure, depending on their desire to live on the edge) some rather diverse physical dangers. Obviously, they risk being bitten by a pet on any given day. They might be the victim of Georgey the Cat's foul mood and razor-sharp teeth, or they might find that Mr. Figgles chomps on their fingers when they slide his food bowl in front of him. Maybe it wasn't such a bad idea to stick that first aid kit in the car after all.

You might have thought the next physical hazard only happens on cutesy commercials or in Disney movies, but think again.
You know that retractable leash that allows Sir Woofs-a-lot to explore all the peed-on trees within thirty feet? Well, watch out for the crafty dog who, while his sitter absent-mindedly strolls down the sidewalk, wraps the leash around a tree and through legs, improvising an ankle-twisting snare of leash line. He'll just watch with supreme satisfaction as the sitter loses balance and pitches headfirst into a rosebush.
