Petallus I love dogs, and cats, and most animals come to that.
I grew up with dogs and when my children were young we had a lovely lady Dobermann, Elsa. So I'm definitely not anti-dog.
But I don't think it matters if I like dogs or not, I'm just commenting that the dog has previous.
As for 'went for' I take that to mean that the dog attacked, whether it sank its teeth in is not the point. It's splitting hairs to try to differentiate between going for and actually making contact - the urge was there.
The OP said in the older thread that the dog had been growling at the children, so there was plenty of warning before this incident.
