Where are the venom-delivering fangs located in the mildly venomous Western Hognose Snake?

Toward the back of the upper jaw (rear-fanged)

The Western Hognose Snake possesses a rear-fanged dentition system, meaning that the structures capable of injecting venom are situated towards the posterior end of the maxilla, or upper jawbone. This anatomical arrangement contrasts significantly with the front-fanged systems found in groups like elapids or pit vipers. Because of this posterior positioning, the snake must often position its mouth in a specific way, or engage the prey deeply, to successfully deliver venom. Consequently, delivering a medically significant dose to a larger animal, such as a human, is difficult for the Hognose, leading to bites that typically only result in minor localized reactions like slight pain, itching, or minimal swelling.
