The Animal Rescue League of Berks County has issued a Code Red for Reading beginning Tuesday and continuing through Saturday due to a sustained heat index of over 95 degrees forecasted for Berks County. It will be in effect Tuesday, 1 p.m. to 6 p.m.; Wednesday, 2 p.m. to 5 p.m.; Thursday, 1 p.m. to 7 p.m.; Friday, 11 a.m. to 8 p.m. and Saturday, 11 a.m. to 7 p.m.

Owners and caretakers of dogs within Reading must keep them indoors except for supervised bathroom breaks and exercise because of the temperatures that are forecast. The measure was added to the city code in 2015.

Noncompliance can result in the animal being removed by an animal control officer from the property and impounded at the ARL in Cumru Township.

Owners would have 48 hours after the Code Red has been lifted to pick up their dogs, and will be subject to applicable boarding fees.

Anyone witnessing an unsupervised dog left outside in Reading during those hours should call the ARL at 610-373-8830.
