Dak Prescott's pit bull is possibly facing the death penalty after attacking a neighbor in Frisco, Texas last week ... TMZ Sports has learned.
Prescott's dog was quarantined last Monday after it escaped from Dak's home and attacked a woman who was transported to a nearby hospital to be treated for her injuries.
The dog was supposed to be held in quarantine for 10 days -- which means it was scheduled to be released today -- but there's been a change of plans due to the seriousness of the incident.
