The Port of Hood River is advising Waterfront visitors to keep their dogs on a leash after a dog was reportedly sickened by animal poison after being at the Event Site beach. Port maintenance crews did find animal poison in an isolated area of the beach Wednesday afternoon and cleaned it up. Two subsequent sweeps of the entire waterfront area did not find anymore of the product. Warning signs have been posted at the Event Site beach. The Port is urging all waterfront visitors to keep their pets on a leash at all times, and to notify them immediately if they see any other poison pellets in the area by calling 541-386-1645.
