You will want to have some idea how to administer emergency first aid to your dog, even as you get her to the veterinarian as quickly as possible.
Things to consider: How to care for the dog and get to the vet, use of a muzzle, and how to relieve some of the dog's pain.
Transportation Plan - First aid for dogs should not replace an immediate trip to your vet, for sure. However, neither should that imminent trip to the vet replace your responsibility to administer emergency first aid on the spot. The best way to handle any dog first aid emergency is to get the dog into the car as quickly as you can, and climb in the backseat with her to administer first aid and any dog medicines you might already know would be appropriate while you have someone else drive you to the vet. In addition, before you get in the car (if neither of you have a cell phone on you) have someone call the vet to inform them of your impending arrival.
Prepared with a Muzzle - A muzzle is rarely thought of as a key component in a dog first aid kit, but even the most placid of dogs could snap or bite at anyone, even her owner, if she's in enough pain and shock. In addition, she may start obsessively biting, licking, and/or chewing at her own wound too. Help your dog from making an impulsive mistake you will both regret. For your peace of mind if nothing else, have a muzzle in your dog's first aid kit, and then just hope you will never need it.
Emergency Medications - However much you are able to handle your dog's first aid emergency on the way to the vet, you can certainly do what you can to make your dog more comfortable and relieve his immediate pain. You can find a number of dog medicines that you spray on a wound to alleviate itching and pain. From Allercaine to Cortisone to Witch Hazel, there are a number of topical pain relievers that will make the dog calmer while you or the vet administer first aid.
