1. I'd tell that owner the next time he loses control of his dog it's game on. What the fuck is a pit bull doing living in an apartment. Socks first then shoes. If you own a dog you need a yard. They're animals not substitute children.
so agree! you should see people here in manhattan. theres people who own labradors, german shepherds, huskys, even st bernards and keep them in their apartment, and just walk them 1-2 times a day. it's sad and cruel. imagine a big dog sharing a 500sqft space with a human 35 stories up. and unlike mini-dog owners, the people who own the big dogs tend to not pick up the dog's shit when they go on the sidewalk or park. i've seen a st. bernard take a shit on the path in strawberry fields in central park...and then the owner walked off like it's not her problem. big fucking 12"x3" turd right next to the john lennon memorial. i wanted to strangle her.
about the original problem......no dont call the cops. thats the sissy-nanny thing to do. get a taser, use it on the pitbull. and dont forget - dogs are not immune to kicks. next time that pitbull charges at you or your dog, imagine it's head is a soccer ball. it may try to bite your kicking foot...but if you hit it's face hard enough and you're wearing half-decent shoes, you'll be fine.
i've done it dozens of times. years ago i lived in a suburban area with a real nasty german shepherd who would chase me on my bike whenever i rode by. so one day, i took a walk, and as soon as it charged, i kicked it in the face as hard as i could. i knocked it down, and it looked like it just got angry. so i punched it in the nose, and immediately it started whimpering away, and then i kicked it between it's hind legs as it was going away. i was 12 at the time. the owner complained to the cops, the cops came to see me, and they were amazed and gave me kudos and told the complaining owner to shut up and train his dog to not attack people.
