Which, I assume, is why marialh said she does intervene if the other dog is on-lead....

I 100% agree with what Livercake said earlier.
In general dogs are very much the best teachers, and people really shouldn't intervene unless it is absolutely necessary... the best way to intervene is to just walk away... normally this helps to diffuse the situation.
By the owners pulling their dog away when they tell your pup off, he isn't learning that his behaviour is inappropriate. Dogs are far better at reading dog body language than people are...
We often meet 2 gorgeous chocolate labs on our walks....

they are litter brothers and are about 9 months old now. One is very much bouncier than the other, and I was talking to the owner the other day about them losing their puppy licence.... we saw him again after that and he said how true it was - the bouncier one especially was getting told off loads... (He only needs to look at Honey, and she gives him a warning bark, before she then plays... whereas the other, who is still very confident, Honey has never needed to tell off at all!)... he said the bouncier one had even been pinned to the ground by a dog who'd had enough of his rudeness... but it's the way he will learn...
There are some times when you have to intervene in doggie interactions.... is a bouncy puppy is pestering a very old dog, if either dog is becoming stressed or anxious by the interaction... or if one (or more) dogs seem to be bullying another.... but generally dogs do best when left to police their own interactions...
