You've every reason to feel upset - so would I be. If you have any ripped clothes, or your dogs need treatment at the vets, then there's the chance that the owners of the attacking dogs could be made to pay, but if they can fulfil the criteria that the police'd ask them, then I'm afraid you might just have to accept that what's done's done. I was mortified when ours got out. It was through someone leaving our gates open, but fortunately the damage to the other dog and its owner was negligible. Even so, we offered to pay any vet's fees, etc. The police came to check our dog out. Daft as a brush - as they could see - but we have ours chipped, collared and tagged, and everything in order. Nothing more was done about it, but had the dog been allowed to roam, and hurt another animal or person, then he would've probably been put down.
