aww, he's still a beauty, and it's amazing at how well they adapt, he's a lucky boy to have a devoted family!
I had a one-eyed-wonder-pug, he was a rescue, and if I (or someone else) didn't take him, he would most likely have lost his other eye, and then have been put down. His "family" wouldn't give him his medicine regularly and he would get out all the time and had been hit by a car... I had just moved to the area and had brought my pug to the vet to start a relationship for care, and he practically begged me to take this poor dog, so... I did. his meds were so harsh on his gut (eyedrops eventually run down the throat after all) and were giving him all kinds of other problems, so I put him on herbs. His tear production was well within normal range within 2 months and all his other problems cleared up. he was happy and eager to please, so he trained really easily... my neighbors who had 4 little kids, fell in love with him, so I gave him to them, he lived a great life...
all of my animals (except for my current Pug) are rescues, even my chickens. (someone ran over my previous Pug... driving like a bat outta hell on my backwoods dirt road... I was so heartbroken and there were no Pugs at the Pug Rescue Society within 150 miles, so my Dad got Ruby for me from a Nebraska breeder... when I went to Denver to visit for Easter, she was in my basket...)
