Don't leave home without it
Please, take your phone with you, when you walk your dog. Three weeks ago, 5.45am one morning, I tripped on some old fencing wire and broke my arm (fractured head of radius), while walking Nitro. I made it back to my car, but couldn't drive my stick shift (manual) car home due to the injury. My neighbour rescued us and took me to hospital, my adult kids slept through me trying to contact them. Always take your phone.
