We see a lot of eye injuries and one of the main reasons for treatment success is how quickly the dog is brought in to see a vet. If you have a dog that is holding its eye closed or has a cloudy looking eye or something protruding from its eye, bring it in asap. We are entering grass seed season as well and a dog that suddenly is squinting is highly likely to have a grass seed in its eye. Waiting to see if it will come right increases the chances of blindness or the dog losing the eye altogether.
