My dog, Merlin, has learned that when the low battery warning starts I bring my drone in close and I guess his herding instinct kicks in. My vet had commented that he was becoming overweight so when I realised he liked chasing my drone I let him. I have to tie him up to take off and land which is a pain. One day he and I were so carried away doing this that RTH kicked in and it landed before I got him tied up. He grabbed it but did no damage.
