If you're on the fence about the Lyme vaccination, so was I, until our border collie got Lyme disease for the third time in her 8 years. We then vaccinated her, and our corgi too when she was a year. Fast forward a year, and the border collie was clear (Hallelujah!) The corgi had a "lesser version" of Lyme's we were told, and must've been because the medication for it was less than half the price.
