Saline Eye wash? • Health and Nutrition : Gun Dog Forum 2013
To prevent dry, irritated eyes, you can wash your dog’s eyes on a regular basis (e.g. once per week) with a saline eye wash and an eye dropper. This solution cannot be used instead of a treatment for an infection, but may moisturize the eyes.
Homemade eyewash solution for dogs is a good thing to keep on hand. It is useful if your dog gets chemicals or debris in her eyes. Dripping flea dips and sprays are common eye irritants that trouble dogs. A good saline eyewash will bring soothing relief to your pet and help prevent further damage to the eye.As many dogs are skittish when someone tries to administer eyedrops, it is important to remain calm. After washing your hands and shaking the saline solution, sit down and put your dog between your legs with its back to you. Tilt your dog's head back and hold its eyelid open. (Alternatively, make a pouch of your dog's lower lid by slightly squeezing it together.) Place the eyedropper or bottle close to the outside of your dog's eye. Quickly squeeze the drops into the eye. Allow your dog to blink, which will help spread the solution over the eye. Also, administer the saline solution several times throughout the day, as it is washed away by tears.Nope, not safe.
Dog eyes and human eyes are different. A simple saline wash might be ok, but if the dog has any kind of injury to the eye (which cannot be seen with the naked eye and needs a vet's diagnosis) even that can cause swelling or enough irritation to blind a dog in certain circumstances.
So, no. Don't use over the counter human drops. Go to the vet and have them check out the eyes for any kind of scratches or injuries and infection and get the proper drops that are needed for his particular condition.
