We have a new family who just moved in over the road, nice enough looking guy, corporate type with a young kid, oh and then there's Charlie, his lab mix from the pound. Just went over to pick up my mail from the box directly opposite his house, and he's out spraying his yard with Charlie in tow. I hear him trying to get the dog in the house, and suddenly I'm thinking about pepper spray, next thing Charlie ambles over to me all friendly like, and when he gets to about 10 feet he turns into Cujo, all raised hackles and teeth, but no bite. I stand my ground and the owner comes running over. "He's never done THAT before" he says, and delivers a very un-corporate open hand slap across the dogs face causing it to cower in the street. Five minutes later I'm back out to put the outgoing mail back in the box, this time with a can of Fox Five Three and a .380 - just in case things get REALLY out of hand. Dog is still out and he blocks it from leaving his driveway shouting apologies again, but this time his elderly female next door neighbor comes out of her side gate, and Charlie makes a body swerve towards her - exactly the same M.O., approaches her slowly and friendly and then goes Cujo at about 10 feet. She doesn't take it so well, and turns a little Cujo herself, first she screams, then yells "GET THIS F'IN DOG OFF ME" and this time the dog is right up in her face and looks ready to bite. Bottom line, just how is it best to deal with this, it didn't seem bad enough to call the Rozzers, but something seems approporiate. Advice/suggestions appreciated.
