I honestly can't recommend Shoe Lab any higher than what I'm going to try to do here. They are, much like Scotty from "Star Trek", "Miracle Workers".
They've helped me out twice through dog related damages. One of my pups clawed up an antique chair that was my Dad's, and I was devastated. I sent it to them before I went on a vacation, only to come back to it looking brand new, better than it had in the first place. Four years later, it still looks great.
A few weeks ago, another one of my pups thought it would be HILARIOUS to chew one of my favorite belts I've had for years. It's not an amazing belt, but it's sentimental, and I didn't want to admit its end as becoming a chew toy.
Thing was, I forgot about Shoe Lab, and looked for a good leather repair place. When I pulled up, I remembered this place from the last time, and felt better about my belt's fate. The next day, it was back. There's a tiny, minor indication of where it got damaged, but I would have to really point it out to someone in order to see where it took the original damage.
Shoe Lab is great. They have come through twice when I've really needed them too, and the work has looked good, and held up. A little pricey, but they give you an estimate, and the work makes up for the value.
The next dog crisis or general refurbishment, I'll be coming back here without hesitation.
