A man now faces charges of assault against a police officer after he allegedly bit an officer serving an arrest warrant for animal abuse stemming from reports that he threw three newborn puppies—umbilical cords still attached—over a six foot fence.

According to KRGV-TV, officers with the McAllen Police Department arrested the man—identified as 33-year-old Nedio Alaniz Jr.—on Sunday.

A judge had signed an arrest warrant for Alaniz in May but had not encountered him until they responded to a disturbance call.

The officer—whose identity has not been released—was transported to a nearby hospital for treatment.
