No, as eye problems can go bad fast. Waiting in this instance is the one time being patient may not be to your horse‚Äôs advantage and veterinarian assistance will most likely be required. Once an infection gets established in the eye, it gets difficult to treat and the danger of losing site or the eye is very real. The time frame can be short and hours can make the difference. If you notice your horse squinting, we wouldn‚Äôt recommend even wait until morning to seek help.
