Brachygnathism

Brachygnathism, or colloquially parrot mouth, is the uneven alignment of the upper and lower teeth in animals.

Horses with parrot mouth often require dental treatment at least every six months to remove the hooks and maintain alignment.

[1] The equivalent conditions in humans are termed retrognathism or prognathism depending on whether the lower jaw is too far back or too far forward respectively.
