The Nebraska Humane Society is offering reward money for information about two dogs they suspect were poisoned.

Humane officials announced Wednesday a $1,000 reward for information leading to the arrest and conviction of anyone responsible for the dogs’ deaths.

The dogs became ill in mid-November after being kept in their fenced-in backyard. They died a short time later.

Humane officials say a light-colored meat found in the backyard tested positive for a poisonous substance. They suspect someone may have thrown the tainted meat into the owners’ backyard.

Humane officials also say they’re investigating reports of contaminated cat food found on sidewalks in the area.
