When Charlie the golden retriever lost his sight to glaucoma (he is 11, or 77 in people years), his humans were worried about how he would get along. They came up with a plan--and it is a 4-month old golden retriever puppy named Maverick--who will be Charlie's seeing eye puppy.
They have their own Instagram page: https://www.instagram.com/charlieandmav/
"Charlie had glaucoma which led to his having his eyes removed. Now, Maverick is here to help Charlie around and Charlie is trying to teach Maverick manners," the post said, adding that the manners part was a work in progress.
Even though Maverick is supposed to be helping Charlie, they seem to be helping each other.
