What is underbite and overbite in dogs?

In dogs, an underbite and an overbite refer to two different types of misalignments between the upper and lower jaws:

Underbite (prognathism): An underbite occurs when the lower jaw protrudes beyond the upper jaw, resulting in the lower teeth overlapping or extending in front of the upper teeth. In severe cases, the lower teeth may even be visible when the dog’s mouth is closed.

Breeds like Bulldogs, Boxers, and Shih Tzus are more prone to developing underbites. While a slight underbite might not cause any problems, severe cases can lead to dental issues, difficulty in picking up food, or potential jaw misalignment.

Overbite (brachygnathism): An overbite refers to a condition where the upper jaw extends further forward than the lower jaw. This results in the upper teeth overlapping the lower teeth, and in more severe cases, the lower teeth may not even make contact with the upper teeth. Many dog breeds can have a slight overbite, and it is generally not a cause for concern unless it is excessive. Breeds like Dachshunds, Greyhounds, and Collies may be more susceptible to overbites. However, severe overbites can lead to dental problems, difficulties in chewing, and potential injuries to the gums and palate

Both underbites and overbites can vary in severity, and the consequences depend on the degree of misalignment. If you have concerns about your dog’s bite, it’s best to consult with a veterinarian or a veterinary dentist who can evaluate the situation and provide appropriate guidance.
