Authorities in Bandera County are trying to determine who attacked the Plott hound dubbed Ziggy by the Montes family. They run Mission: Miracle K9 Rescue.
The San Antonio Express-News reports Ziggy was rescued in September but got out of his enclosure Sunday near Bandera.
The dog later returned but Mary Montes and her son, Matt, were horrified to see an arrow through Ziggy's abdomen. The point and the feathers were cut from the ends.
A veterinarian in San Antonio euthanized the dog Monday.
Conviction for animal cruelty, a state jail felony, carries a maximum penalty of two years in jail and a $10,000 fine.
