We had a nightmare story with Wag. My sister's dog was being walked by a new walker through Wag. The sitter brought our dog to a nearby fenced-in handball court and let him off leash, which he was not supposed to do. Her dog went to retrieve a ball that was stuck between the concrete padding and a chain link fence and in so doing severed several arteries in his paw.<p>The handball court looked, no joke, like a multiple murder scene. Dogs have 7 arteries iirc through their paws and so there was blood - everywhere.<p>I know this because I happened to have left work early and was eating dinner with my family nearby when my sister, away at work, gave me a frantic phone call that the walker called, freaking out, that her dog hurt himself and 911 refused to pick him up.<p>I ran to my car as far as I could, drove down to this park, wrapped up his paw, carried him into the car, and drove, breaking every light to the animal hospital. Along the way NYPD pulled me over and upon finding out what was going on, proceeded to escort us to the hospital, clearing the way (shout out to the 88th).<p>If I wasn't home, I'm not sure her dog would have lived. He needed several days in the hospital, blood transfusions and minor surgery. The walker could not have handled it poorer, he was hyperventiliating, completely freaking out, and couldn't get control of himself. I was nice to him, gave him water, calmed him down, but jeez he was a mess. No training, no proper incident response.<p>Don't use Wag.
