Animal rights activists have turned their attention to an Iowa case of a man charged with causing the heat-related death of a German shepherd.

The Des Moines Register reports that about 20 animal rights activists rallied outside the Polk County Courthouse on Friday morning, pushing for the maximum jail sentence for an Urbandale man charged with animal abuse.

Urbandale police say 18-year-old Luis Angel Lara-Leyva failed to provide his dog with water on a 90-plus degree day in June, causing the dog's death.

The Des Moines-based St. Francis Foundation for Pets organized Friday's rally, collecting nearly 1,000 signatures in addition to 1,000 already collected for a petition demanding that Polk County Attorney John Sarcone seek the maximum of a year in jail.

Lara-Leyva's trial is set for Oct. 24.
