So upset and shocked for you all Maddy.
I really understand your dilemma though, as it s not easy to share land with a neighbour, and to have a fallout!
My worry is that if this dog is a friend of your neighbour it is probable that it will be back again. This time Willow wasn't seriously hurt, but next time the dog might get a stronger hold of her.
If you feel reluctant to report it this time Maddy.......tell your neighbour how you feel, and that there will be no hesitation in contacting the dog warden if it comes anywhere near your dog again. Stress, too, that OH was hurt. I would also say there were witnesses who saw the whole thing from their windows, and although you are not reporting it this time.....ONE of them MIGHT
.
I hope you are all going to be ok Maddy. These attacks unnerve us badly.
Sending you all love and healing thoughts. Xxxxx
