Dogs that spend extended periods of time outside are also susceptible to frostbite – and even hypothermia.
Dog owners should check frequently on their four-legged friends.
"They need to have adequate food sources in order to continue to generate heat," said Dr. Tim Fouts, of Hillside Small Animal Hospital.
"They need to be fed regularly and they need adequate shelter – especially from the wind when the windchill drops down – because that makes the hypothermia even more of a problem," said Dr. Fouts. "Most of the time, that means shelter on at least three sides.
Dogs' ears, noses and feet are most vulnerable to frostbite.
A dog suffering from hypothermia may stop shivering and become lethargic as it's body core temperature takes a dangerous plunge.
