Firefighters in Reading rescued two dogs that went through the ice Sunday.

Reading Fire Department and Hillsdale County Sheriff’s Department were dispatched to Sunset Dr on Round Lake. Two dogs had fallen through the ice.

One of the dogs died from exposure to the cold water, and the other was rushed to a local vet.

The Michigan DNR says you can’t always tell the strength of ice simply by its look, its thickness, the temperature or whether or not it is covered with snow.

The DNR does not recommend the standard “inch-thickness” guide used by many anglers and snowmobilers to determine ice safety. A minimum of four inches of clear ice is required to support an average person’s weight on the ice, but since ice seldom forms at a uniform rate it is important to check ice thickness with a spud and ruler every few steps.
