with his health,' Mr May wrote.

'He developed diabetes and lost his eyesight. 
With medication we got his diabetes stable and he qualified for eye surgery to give 
him back his sight. Here is seeing my parents afterwards.'

'It broke my heart seeing this dog I grew up with, who I see as a very good friend…
running into things, not being able to recognize me……just struggling,' Mr May wrote on Reddit.

'It literally brings tears to my eyes every time I watch it, 
as much as I love it I just wish I could have been there. I’m just so thankful 
for my parents for taking care of him like this.

I can only imagine what went through his mind that one day it went black…..
and then suddenly he can see everyone again….. 
I can’t wait to get home over Christmas so my dog can see me 
for the first time in two years,' May wrote.

The surgery to repair the dog’s eyesight cost $5,000.

'I know most people will that that was a waste of money but whatever. 
He’s happy and he makes us happy, he’s family to us, you can’t put a price on family,' 
Mr May said.
