Don't you just love it when you're in the park with your 4yo, 2yo and dog (who is, as a dog should be, well trained and under control) and someone else's out of control dog comes charging over and starts jumping up and grabbing at your ball thrower while the owners do... absolutely nothing? And then when the dog finally goes they don't put it on lead, but let it do exactly the same thing again five mins later nearly knocking the kids over.
Owners finally ran down when I pushed the dog away. Apparently I'm in the wrong for moving their dog away and he's "scared" of the thrower (least scared dog I've ever seen, he was having a whale of a time grabbing, tugging and barking at me) and I'm a bad mum for hitting their dog. Mate, you'll know if I hit your dog and if you can't control it I'll control it for you and will absolutely push it away from me and my kids. For future reference, the correct response is to apologise profusely the first time, put your dog on lead and get some training.
