Always remember: When providing first aid, the most serious threats to life are treated first.
Emergencies that may require first aid would generally be the result of an automobile accident, cuts, burns, animal or snake bites, electric shock, heat stroke, poisoning, or insect bites and stings. First aid measures are to be used only to keep the dog alive and relieve pain for the amount of time it takes to get to a veterinarian.
In an emergency keep calm and keep a level head. Appraise the dog's situation then call your veterinarian or the local pet hospital for advice.
Keep emergency phone numbers near your telephone.
Try to keep your dog's body warm (but not hot) and to restrict his movements by placing a blanket, your coat, or a thick towel over him in order to let his own body heat warm him up. Keep him as quiet as possible, and keep movement to a minimum.
Try to avoid changing your dog's position when he must be moved.
If your dog is young or small he should be carried in your arms, a box, or basket. Larger or adult dogs he should be carried by two people using a blanket as a stretcher. Gently place the dog into your car.
Give no food or liquids because emergency surgery might be necessary.
Get to a veterinary hospital as soon as possible, but drive carefully!
The bottom line – In all cases get him to the veterinarian because even small cuts can become big problems due to infection, and there can be internal injuries you can't see and your dog can't tell you about.
