Was walking home with our dog last weekend when spotted a dog coming out of the side road who I know our dog doesn't get on with (our dog can be reactive to other dogs when on the lead and they have growled at each other in the past). Crossed over to avoid them, they crossed too. Stopped and waited til they went past. They walked off up the road but their dog somehow wriggled out of its harness/ collar, ran back up the road and attacked our dog. He's walked in a muzzle and was on the lead so couldn't react. He's been left with three bite wounds on his leg. An emergency trip to the vet's has cost £200! I've been over to the owner's house and given them a copy of the vet's bill and (very politely) said given the circumstances we feel you should really pay it. They said 'leave it with us'... Then nothing since. How long do we leave it? Should we go back over this weekend? Contact a solicitor? Police?
Advice appreciated!
