My daughter plays quite roughly with Banjo. It's a bit of a pain sometimes, because clothes have been torn and sheets wrecked (she hides under MY doona and encourages the dog to "dig her out" - sigh). But it's great that they play nevertheless.
But recently Banjo has growled at her a couple of times. It is usually when she is sitting or lying on her.
I know you should never punish a dog for growling as that could make it more likely that they will bite without warning. But so what is the best way to react to it? Is just backing off enough, as clearly it is my daughter's fault for going too far?
