I don't care for flowermummies. :P
The fact is - as far you don't beat the dog hard - i never said to beat them til they poop themself. Hm the fact; dogs tell dogs of with nipping/biting and sound. Standing there for hours trying to do the doggie cutie want a treat thing is just not the best way to make 2 big strong dogs not pull. What i did with my dog (it was pulling like a madman when seeing a dog or cat) was simply a (not screaming) no and a light slap on its ass. (fyi im italian, my english stink).
Now she only pull out of happyness the first half km of every walk.

But in the line were walking, not risking to get us both killed under a car.
