Note that Sammy has full beagle ears, is much whiter than Sass, and tail is not as fluffy. He's also male. Sass is a 4 year old brown/white/black beagle mix with a distinctive white tipped tail that curls back towards her head and ears more erect and smaller than a typical beagle.
Of course, some folks are asking if the tracking dog could be mistaking Sammy for Sass. When we have a positive track, the tracking dog is able to distinguish between dogs based on smell, not appearance, so the tracks in the neighborhood should be of Sassafras. (We had another sighting of a beagle in Glenwood cemetery where we used the tracking dog to confirm that it wasn't Sass.)
