A 27-year-old driver has been arrested after allegedly 'doing donuts' on a frozen river until his pickup truck smashed through the ice - then saving his own life while leaving his pet dog behind to die. Andrew Mayer was traveling through New Jersey with his two-year-old boxer mix, Rolo, in the early hours of Sunday  when he reportedly drove onto the Toms River, which had completely frozen over. He then repeatedly drove his 1989 Mazda B2200  truck around in circles, causing it to plunge through the ice into the frigid water below, police said. Mayer escaped from the vehicle as it was sinking. However, he allegedly left Rolo inside the truck, which was quickly filling up with water. Divers later found the black pup lying dead on the backseat of the sunken vehicle after a passerby called 911. Scroll down for video .
