Bright Eyes

I am looking for a solution to treat dog cataracts. Can you recommend any eye drops which would be suitable?

I know there are many on the market, and I have heard of Ethos Bright Eyes, but I am unsure how effective they are as a treatment. I am sceptical of reviews online, as the drops could be an expensive con.

Thanks for your help.

Behind blue eyes

I have picked a male blue merle collie puppy out of a litter; they are currently five and half weeks old, and he has two bright blue eyes. Here is a photo of him:

I already have a blue merle dog who is two years old, and he has one blue and one brown eye. I have never seen a blue merle with two blue eyes; will they stay blue or will they go brown or wall eyed?
