The working relationship between the Marin Humane Society and the county, which has been in place for over four decades, was extended for another three years by the Board of Supervisors last week, allowing the organization to continue its mission to provide animal control services throughout the county. The agreement terms remain about the same as before, save for a few amendments to the county’s animal control ordinance. The amendments were made to keep the county’s edict on par with state regulations. Veterinarians previously had a 10-day window to report required vaccination records for dogs and cats to Marin Humane; now they have 30 days to help catalog the county’s data on diseases like rabies. Another revision enables dogs involved in organized dog fighting to have a hearing to determine if they’re vicious and require euthanizing. (Captain Cindy Machado, Marin Humane’s director of animal services, said dog fighting cases have never been an issue in the county.) The final amendment adds several more exotic animals to the list of species that require a permit from Marin Humane before entering the county. If a traveling animal show includes kangaroos, wallabies, seals, sea lions, walruses, sloths or sharks, the operators must first obtain a special permit. The changes have no effect on organizations like the Marine Mammal Center that are already qualified to handle wildlife.
