Chihuahuas often have underbites due to their genetic makeup and the specific way their jaws and teeth are structured. This breed tends to have a short muzzle, which can contribute to misalignment between the upper and lower jaws. Additionally, selective breeding for certain traits, including size and appearance, has inadvertently reinforced this dental characteristic. Underbites can sometimes lead to dental issues, but they are generally considered a breed standard for Chihuahuas.
