A javelina attacked a woman who was walking a dog near Snyder and Sabino Canyon, Arizona Game and Fish officials say.
The department is warning the public to be cautious around the animals.
The attack happened at 8:30 a.m. Monday. The javelina left the woman with two-inch gashes on her knee.
There was also a javelina attack March 25 in Oro Valley.
"We don’t blame the victims, but we do want pet owners to know that if they see javelina while walking they’re dog, they you should go in the opposite direction. Javelina can’t tell the difference between a dog and a coyote, which prey on javelina, so javelina react instinctively to dogs," said Regional Supervisor Raul Vega of Game and Fish in Tucson, in a statement. "The presence of dogs is the second leading cause of injuries to humans by javelina, which are rare but can be serious. The leading cause of such injuries is feeding javelina, which is illegal."
