Welcome to the board, Nancy!
We often will flush our dogs' eyes with sterile saline if they're bloodshot. It soothes the eye and may clean out debris if that's the problem. If the redness doesn't resolve in a few days, it's time to see the vet. If she starts pawing at it or the third eyelid starts rolling up in the meanwhile, she'll need to have it looked at as soon as possible.
