Dog bit DS this morning.

[whatstepNext]

I am not an experienced dog owner and I need some help over what to do next. I've NC for this.

Our dog is pretty new, a rehomed pointer, only had her 4 months. She lived with a family previously, who had young children, so had a good history of being ok with them. Her age is unknown but thought to be over 8. She is the sweetest, loveliest and most affectionate girl, we all love her and she's settling in well (bit of separation anxiety but getting better).

DC1 is 5 and very gentle and calm. No issues at all there. DC2 is 3 and a very different personality, loud and boisterous. We have worked hard to teach him how to touch the dog appropriately, feed her treats, not shout near her, away from her bed, when sleeping etc and he's improved massively. Obviously I try never to leave them together unsupervised but today I went back to the bathroom to get something and was gone for about a mintue, no more. According to DC1, DC2 put his shoe on the dog's head, she growled and then bit his wrist. He was crying and it's bruised but the skin isn't broken.

I'm pretty upset by this- and unsure what to do next. Our lives are full of our and visiting children. I can't see shutting her away all the time as a workable option, will it not just make her more anxious? I haven't told any friends/family in RL as I know most will be of the 'get rid' mentality. A friend of a friend's little girl was very badly bitten by a family dog recently (requring multiple facial surgeries and she has some palsy) and this is just haunting me. Will her tolerance be reduced now as she's already bitten? I cannot be a physical barrier between them all the time.

I've got a vet appt tomorrow to discuss another issue (crusty bit on her ear, doesn't seem to be itchy or painful but getting it checked out anyway) so I will discuss it with them.

Just let me add I do not blame the dog for this at all, she obviously felt fearful and provoked. I only blame myself for not protecting her from the child and my child from the dog.
Any advice appreciated.

Thanks mummylion. I've been reading a lot about teaching children to ignore dogs and basically find them totally uninteresting, so that's my tact, rather than trying to teach him how to interact appropriately, which is easier for him to get wrong

The vet was very lovely, she checked the dog out and couldn't find anything that might have caused pain. Her ear scabs aren't anything to be concerned about either.

She recommended a dap diffuser which I'll get.

This morning I crated her with some treats while we got
ready, and put a blanket over it too which she liked and meant ds can't see her.

I'm going to give the behaviourist a call tomorrow. Thanks again for all the advice and support, I feel a lot calmer!
