Faster than Snyder's hound

there is an old phrase, common in SW Virginia, that something is "faster than Snyder's hound." Does anyone know the origin of that phrase, or who was Snyder, etc. Thanks.

I found the phrase in a regional English dictionary. But it doesn't tell who Snyder was.

Snyder's hound/house cat/pup -- as fast/peart/quick/smart as. The earliest citation is: 1937 Hall Coll. Emerts Cove TN: That plane went over here fast as Snyder's pup.
