The first few days I was in Pittsburgh I saw several greyhounds, which piqued my curiosity.

I met Andy Callaghan at a A Fair in the Park in the Shadyside area and found out why.

Turns out there are a couple tracks nearby and also rescue organizations that help rehome dogs who would otherwise be killed after their racing days are over.

Callaghan rescued Monty (left) and Skye from Pittsburgh-based Steel City Greyhounds.The dogs are pretty well adjusted and let lots of strangers pet them. Both have raced at one of the area tracks. Skye tore her cruciate ligament at some point, but it was never mended.

Callaghan disagrees with the way the dogs are considered disposable in the racing industry and are routinely killed once their 'career' is over.

Though racing is what they are bred for, they are fundamentally hunting dogs and could be happy serving other purposes, he believes. He says its amazing to watch them run for the fun of it.

There were lots of interesting dogs running around at the craft fair. Monty made friends with a pit bull named Fig.
