Suggestions on How to Administer Angels’ Eyes®
Most of our customers have told us the easiest way to administer Angels’ Eyes is to add the recommended weight dosage directly into their pet’s food once daily. Some people use it as a treat and mix it with some baby food, cottage cheese, yogurt, peanut butter, etc. Another suggestion is to add water to the recommended dosage and use a syringe slowly directly into their mouth.

From what I know, you put a couple drops in the water bowl.  Did you put it in his eyes?   I didn’t know that there was an angel eyes product that you put in the eyes.
