This is due to the breed’s natural prognathism, where the jaw grows forward. It clarifies that this forward growth tends to continue until Shih Tzus reach one year of age. Even though some increase in prognathism is expected during the formation stage up to a year old, we assure readers that Shih Tzus with minimal prognathism at 60 days are likely to have beautiful alignments with closed jaws.
Shih Tzus should never display prognathism, attributing such beliefs to the breed’s characteristic short snout. It advises potential Shih Tzu owners to understand these details before making a purchase to avoid misunderstandings.
Emphasizing that mild prognathism is common in short-nosed breeds, including Shih Tzus, the appearance of slightly crooked teeth in these dogs is normalized. It dismisses anecdotes about people wanting to return Shih Tzu puppies due to perceived “crooked mouths” or “defects,” emphasizing that such characteristics are entirely normal in breeds with short noses.
While acknowledging that all breeds with short snouts exhibit prognathism and stating that it typically does not affect Shih Tzus’ health, we highlight the importance of avoiding severe prognathism. Where prognathism is visible with a closed mouth or the tongue hangs out, extreme cases are considered genetic and unacceptable in Shih Tzus according to breed standards.
We encourage Shih Tzu owners to cherish their companions and offer plenty of love and care. We remind readers that one of the distinctive features of the breed is the projection of lower teeth in front of the upper ones, considered a standard. However, we advise against excessive prognathism and advises consulting a professional for any significant dental concerns related to their Shih Tzus’ oral health.
