Types of dog bites
Since we as humans like to categorize, grade, classify, rank, and label, it should come as no surprise that there exists a scale for the severity of dog bites—the Dunbar Bite Scale to be precise. It divides dog bites into six levels:
LEVEL 1—AGGRESSIVE BUT NO SKIN CONTACT
The dog is aggressive, showing its teeth, snapping and growling, possibly snagging clothing, without actually making contact with the victim’s skin. In the case of Level 1, the dog may be showing fear or insecurity rather than true aggression.
LEVEL 2—TEETH MAKE CONTACT, BUT DO NOT BREAK SKIN
With a Level 2, the dog is sending a message that it is uncomfortable with a situation, that it is stressed. People who work with dogs intimately, like vets and groomers, sometimes experience this. The dog’s teeth may leave a mark, but don’t break skin.
LEVEL 3—A SINGLE BITE WITH SHALLOW WOUNDS
Whatever the reason for a Level 3 bite, whether rough play that escalates, fear, poor socialization, or something else, this level of aggression must be dealt with. The dog should be taken to a vet or trainer as soon as possible. This is generally a serious problem that needs attention.
LEVEL 4—A SINGLE BITE WITH DEEP WOUNDS
To be clinical, this is defined as a bite with one to four perforations deeper than half the length of the dog’s tooth. These bites may be caused by predatory behavior, poor bite inhibition, or fear. These are dangerous bites, as the dog may shake its head while biting, refusing to release.
LEVEL 5—MULTIPLE BITES WITH DEEP WOUNDS
Similar bites to Level 4, but in this case multiple bites occur during an attack. Dogs responsible for Level 5 bites are generally considered dangerous dogs. Rehabilitation may be possible with the help of a veterinary specialist or trainer, but it would require a dedicated professional and a great deal of work, with no guarantee of success.
LEVEL 6—DEATH OF THE VICTIM AND/OR FLESH CONSUMED
If reading those words sends a chill up your spine, that’s not surprising. Dogs who commit Level 6 bites are not safe to be around humans, or even other dogs. While authorities will determine the ultimate cause of death, chances are these dogs will be recommended for euthanasia.
