I am a retired canine control officer.. In my State, this is completely against the law. Not only is this woman in line for a summons for allowing her dog off leash, but she is responisble for your vet bill costs!! Do not hesitate to call animal control and report this.. her dog was out of the owner's control, and she is liable for the damages incurred to your precious baby. Although large dogs need a dog park too, I know there are times specified in other States, where large dogs can play, and small dogs too but not at the same time, to prevent this sort of thing from happening. Why not suggest this to your town, so smaller dogs can be protected from this horror happening again. If I were you, I would be at City Hall, tomorrow, and making a complaint, then a suggestion for times for big and small dogs to enjoy the parks set aside for our loved fur ones. I have a big Doberman, and would never allow him to run free in a park with small dogs.. Heck, he cant run free in my home with my zenji puppy he would kill her..I am a very responsible owner, and accidents happen to all of us, but you have the right to enjoy the parks with your babies…without fear of being attacked. If the dog had bitten you, the owner could be sued and fined, and God knows you would win. Not sure how the law works there, but here, she is liable for your vet costs as well. I hope you get her big time, and the umbrella thing, is a great idea but a long riding crop is smart, too.Your poor little zenji is probably traumatized now, and just give her lots of love and huggs and keep her warm .. Give her kisses from Zaharah and Dale.. they send you all their love too. Janice
