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 bring him," asked the receptionist, "or will he come on his own?"
