A year later, Charlie's right eye was removed for the same reason.
Despite the expensive but necessary procedure, Chelsea Stipe said it was an easy decision. She told NBC.
"For us it was a no-brainer, empty our retirement plan to care for this dog because he makes us happy."
Thankfully, the Stipe's paired Charlie up with his own "seeing eye puppy" – a four-month old who is named Maverick.
The pair has established a very special bond that warrants their own Instagram page.
Meet Charlie and Maverick.
Charlie didn't take to the new family member at first, but in a matter of time, Maverick adopted his important role in helping Charlie "see" and won him over.
Chelsea Stipe told TODAY:
"When Maverick and Charlie play, it's definitely great to watch because Charlie turns into such a puppy. It's sweet to see them get along and enjoy each other."
Maverick is such a good doggo; he makes sure he walks close to his impaired companion so he doesn't bump into anything. "They almost turn into little sled dogs where they'll walk together," observed Chelsea.
Despite losing his vision, Chelsea said Charlie hasn't given up on having a good time, and Maverick is ensuring he won't miss a thing.
"When they would play, Maverick would realize that Charlie would lose the toy sometimes, so (Maverick) would pick it up and put it back in front of him to re-engage playtime," she told NBC Philadelphia.
It doesn't get any cuter than this.

Chelsea said the response to her pals's Instagram page has been overwhelming, and other owners whose dogs suffered from glaucoma reached out to the Stipes.
"We have definitely been overwhelmed with the response, but it's such a good thing. We love how positive the community is and how happy (the dogs) are making everyone."
