It's an emergency
Immediate veterinary attention can mean the difference between life and death for an injured dog after all but the most minor of accidents. Getting your dog to the vet's clinic (where all the necessary equipment is on hand) is quicker and gives the dog a better chance than calling the vet out to the scene of the accident. The most important thing to remember in an emergency is - don't panic! - this could cause further anxiety for an already frightened animal and it wastes valuable time.
