Greyhounds have been clocked at 35 mph!  Our chocolate lab loves to get out of the truck at the beginning of the dirt road that leads to the lake.  He then runs to the lake.  He is so excited that he usually runs at 20 mph for almost a mile.

Note that your dog just doesn’t have to be predisposed to being fast, he also needs to be in good shape in order to run fast!
