BJ is 6 months old, we went to the dog park today that we had been there once already, he walked good by my side and sniffed the surroundings, but he pull my leash when I try to get close to the 1 feet tall dog water fountain. I called him to come towards me at the fountain, he suddenly stop and back off 3 feet away and sit still, I try to call & pull him couple time, but he refused and pull my leash very hard and firm and stay in that position untill I walk away from that area.
How does the dog react when they frightened ? Cause' BJ will first back off and try to walk far way from it, and sometimes he start barking when he scare of an object, sometime he doesn't.
Such as a toy( a plastic ball can run by itself , can get it at walmart) i bought for him, I thought he would love it because his Herding Instinct, but he seemed so scare very time I put it on the floor, when he saw the ball moves, first he back-off and he barks. weird thing is he play fetch and tennis ball. why he so sensitive to that?
Also some objects that are not usually in the kitchen Floor, etc a broom, mop, a big cooking pot, a Jar, black garbage bag, supermarket bag, something about 1to2' in height. he will react the something, but he don't do that to humans or other dogs.
It is the react of aggression or fear or something else? How should I help him to overcome this issue?..
