Dog is nearly 3. She has never growled at anyone before, although sometimes she growls at things (eg a big snowball in a field). DS(10) and her were just sitting in an armchair together. She was not asleep. He moved to stroke her chest and she growled loudly. He immediately moved away from her and she jumped down from the chair and onto my lap. She is now happily asleep on my lap. DS is upset because it's not really clear why she reacted like this. Obviously I didn't tell her off, as I know that growling means "I don't like this". DS also knows this but he's not entirely sure what it is he did wrong 😞
I know none of you can actually know why she did this, but what is our best strategy going forward, other than ensuring DS is not alone with the dog?
