I had a German Shepherd that was afraid of cattle.He'd jump out of the truck and wait at the gate for us to come back..My dad asked me to lead the milkcow to the pasture,so a made him come along..He hung back behind the cow,which made her lead better,as she didn't like dogs. We got to the pasture,Phil (the dog) stayed outside the fence..I let the cow go,and walked off to see what was what... Suddenly,there was a moo in front of me,a moo behind me,and the cow was chargeing directly at me!! There was a blurr of black and tan,and Phil was at the cows nose snapping and snarling..He turned her away from me,then ran for the fence..The next time we visited the pasture,he waited at the gate,like always..
At least your dog didn't hide behind you with a cow chargeing..
