As a behaviour professional that often deals with aggressive and dangerous dogs, understanding the severity of any dog bite is critical.
This updated graphic and the related "Putting Dog Bites Into Perspective" are fantastic resources for anyone wanting to understand dog bites in more detail.
If you have a dog that has bitten, it is important to understand not only the context and situation that led to the bite, but also the NATURE of the bite.
Have a read, and feel free to reach out if you need help or have any questions.
Have you heard of Dr. Dunbar's Bite Scale? Have you ever used it?
It's Dog Bite Prevention Week (April 13-19) and any time you're talking about a dog bite you need to start with an objective assessment of the severity and danger, because a "dog bite" can mean a lot of different things to different people, and it can be hard to separate the emotion and subjective experience from the facts of the matter.
Dr. Dunbar's Bite Scale has long been used to evaluate the severity of dog bites objectively by looking at measurable characteristics of the resulting wound. You can download our latest printer-friendly PDF version of The Bite Scale from Dunbar Academy: https://dunbar.info/bite-scale-dadd
This system ranks dog bites on a scale of 1-6, with Level 1 being a "bite" where the dog's teeth don't actually touch the victim's skin, and Level 6 being a bite, or series of bites, that leaves the victim dead.
The difference between rehabilitating a dog that has bitten at a Level 1 or 2, vs. a dog that has bitten at a Level 3 or above is enormous.
Often, dogs that bite at Level 1 or 2 can be rehabilitated quite quickly and safely, because the risk that they will cause a serious injury is so low, so classical conditioning and lure reward training can proceed unencumbered.
Check out the Biting section in the Top Dog Academy for all the tips, tricks, and training techniques you need to start rehabilitating your dog, if they bite at Level 1 or 2.

On the other hand, if you have a dog that has bitten a person hard enough to puncture the skin (Level 3), or worse, you have an altogether different problem on your hands. There is a very real chance this dog will bite someone again, and when they do, there is a good chance they will break the skin again. Rehabilitation is much harder now because of the danger posed to everyone who comes into contact with the dog. The resources in the Top Dog Academy can still be incredibly valuable, but you really need help from a professional dog trainer who can work with you and your dog in person, to see the dog's behavior first hand and help you adopt a strict safety management program to ensure that no one else gets bitten, especially anyone who is unaware of the dog's history.
We suggest you start by looking for a certified dog trainer, either using the database search feature available on either the CCPDT's or IAABC's website. You can find links to both here: https://dunbar.info/dangerous_dogs
If you can't find a certified dog trainer, you may need to work with someone else, but you should review the content in the Top Dog Academy to get a feel for the sort of techniques that we recommend. You certainly don't want to work with any trainer who asks you to use aversive techniques as those will be counterproductive. They may mask the biting problem in certain situations but they will ultimately make the underlying cause of the problem worse, creating an even more dangerous situation!
But if your dog bites at Level 1 or 2, it's time to do something about it. This problem won't get better on it's own, it will take proactive classical conditioning and training. With the right methods, this training can be enjoyable, for you and your dog, and remarkably effective. You should see improvement in a single sessions, and over the course of a few days, the changes should be incredibly obvious. Stick with it and in a few weeks you can transform your dog and get back to enjoying life together, without the stress and worry that you and your dog have been living with.
