...my comet will be 6 months tommorow, and he gets his last Bordatella booster shot on Saturday. I have yet to take him to the groomers for fear of him developing this virus. Even though groomers say that dogs need to have the bordatella vaccine, I doubt if they really screen people by asking for the dogs vaccination records. Vaccinating and using all precautionary measures will keep your dog healthier and happier in the long run. This has been my experience with my yorkie.
