My family and I were hiking on the Deep Gap trail in Blueridge, and this crazy German shepherd mix came out of nowhere and started attacking our dog. I have no idea what provoked this dog to this level of viciousness, but it turned into an all out brawl Our dog is a pittbull mix, so she was luckily able to hold her own. We had to repeatedly kick the dog before it would back off, but it still followed us all the way back. We warned everyone in parking lot an then we called park services
