I read a long time ago take a bottle of hot water with you, a squirt type, and put cayenne pepper in it, because that will wear off eventually. Squirt him a good one when he gets close enough and that should take care of it. It is scary to get chased by a dog; I love them too but was chased home (about 1/5 mile) from a neighbors house by their GS that had pups, and she was just crazed when she had a litter. I ran through a corn field to keep her away from me. SCARY. I wasn't even near her pups either, she just thought I was a threat I guess. Be careful!!!!!
