A sequence of action shots is easy with most cell phones by simply dragging down as your taking a photo. As an example, here I was below the dog's eye level, and took a sequence of 20 photos as the retriever retrieved a greenhead I just shot. Then I picked out my favorite action shot from the sequence of 20 photos. Since the dog is moving right to left, top to bottom, I try to have "negative space" in the photo for the dog to move into.
My dog is 4 and she became gun shy at about 1 year old. Took me a couple years to work it out of her. She loves hanging with me now for waterfowl field hunts but had never retrieved a duck or goose. Loves fetch with a ball, would run up to the downed duck or goose but just wouldn't pick it up.
This was her first ever retrieve a couple weeks ago. Pheasant landed in tall grass nearby in field hunt, she saw bird and looked interested. So we walked over, she kicked it up, I winged it and she was on it like white on rice. First ever retrieve and I was a proud dad and on cloud 9!!
