Charlie was an urban hunter who specialized in hunting tennis balls. I'd take him to the old orchards, fields and woodlands that surround our neighbourhood as well as to the community tennis courts.
"Where's the ball" would lock Charlie into hunting mode. He'd blindly follows his sensitive nose which would be about an inch off the ground while. His tail's wagging speed told me how close he was to his little round quarry. I wsa always amazed at where he'd find a ball, how many he found and how fast he found them.
When we worked as a team we find even more balls + faster because I am taller, hunt by sight and can retrieve balls that he finds but can't get at.
Charlie and I employ the same basic complimentary hunting skills that Charlie's and my ancestor's used when they first met at the dawn of time.
Sometimes it's hard to trust someone who is very different from who you are, how you are, or how you think. But . . . the rewards can be incredible!
