How to help a dog with cataracts
Know the signs of cataract growth.
Cataracts develop over time and the key is to treat them early. As a dog owner, make sure to inspect your dog's eyes on a regular basis.
Look for any indications of a cloudy appearance or a color change. If your dog already has cataracts, watch to see if the impacted area grows or changes in shape.
