(Hillsboro, OR)  --  Washington County Animal Services officials are urging pet owners to plan now to keep their pets safe on the upcoming Fourth of July holiday.  They say you should verify that your pets' tags and microchips are updated, and that your dog is licensed.  Check fences for loose boards or other places where a frightened dog could escape, and make sure gates are latched.  Ask your vet about medications to reduce your pet's fear.  Have a "safe room" in your home for pets during the fireworks, and turn on a TV or radio to help muffle outside noises.
