How Strong Are Tibetan Mastiffs?

Tibetan Mastiffs are strong enough to kill humans and other dogs. Their bite strength depends on the situation. When triggered, they can cause serious harm to their victim.

With a bite strength of over 500 psi, Tibetan Mastiffs can cause a lot of damage to their victims. A Tibetan Mastiff’s bite can reach all six levels of a canine bite.[1]

Level 1 (Non-Contact)

On the first level there is no contact between the dog’s teeth and its victim. Air biting is usually used by dogs as a self-defense mechanism. 

They use this gesture to scare their opponent, without getting violent.

Level 2 (Skin Contact)

Skin contact takes place on level two, but without teeth puncture. This is a way to warn someone that they’re willing to fight if needed. 

If this behavior occurs in your Tibetan Mastiff, look for fear triggers.

Level 3 (Puncture)

Level three is represented by one or more bites with shallow skin punctures. From this level on, it is vital to go to a doctor for treatment. 

Multiple bites usually mean that your Tibetan Mastiff isn’t fully conscious of its actions anymore. The less time between bites, the more dangerous it is.

Level 4 (Deep Wounds)

A level four bite is a single but deep wound. It can also be accompanied by slushes and bruising if the dog shook its head while attached.

At this point, your Tibetan Mastiff shouldn’t be let around strangers until coached by a professional. Bites at this level are fatal for children.

Level 5 (Serious Wounds)

Several dangerous bites occur on level five. The nature of the wound on this level is similar to the one in level four, but with multiple bites.

Depending on the number of bites, the victim can end up with serious damage or even lose a limb.

Level 6 (Fatal)

On the last level, the human or animal attacked is killed. The wounds on level six are either deadly or close to it. These kinds of bites are rarely seen exercised by domesticated dogs.
