On September 5, 2014 the WooFDriver took the WooFPAK for a Free Ranging run in the Shenandoah Valley. Here they got on the scent of this little groundhog. Luckily for him groundhogs are very capable tree climbers! Did you know that groundhogs are on of the few species that enter a true hibernation? In most areas they hibernate from October until March or even April! That’s a long slumber!!
