In his younger days our golden retriever, Catcher, often ran away when he had the chance. His veterinarian's office was about a mile down the road and Catcher would usually go there. The office staff knew him and would call me to come pick him up.
One day I called the vet to make an appointment for Catcher's yearly vaccine.
"Will you be bringing him in yourself," asked the receptionist, "or will he come on his own?"
