It's still important for dogs to get fresh air and exercise, but limit exposure time, San Filippo said. Small games of inside fetch, for example, could help offset less outdoor activity. And when out in the cold, if pets are comfortable wearing them, coats and boots are a boon. (Your vet can help you make sure booties are properly fitted, according to the AVMA.) Pay special attention to pets near slippery ice, and be sure to leash dogs near frozen lakes or ponds.
Check tires, too, for sleeping cats:
On the way inside, San Filippo recommended examining unbootied paws for antifreeze irritation or rock salt caught between pads. Indoors, warm spots, perhaps augmented by space heaters (provided the devices are out of reach of a wagging tail or inquisitive paw) can help ensure dogs, cats and other pets aren't too cold. And, per the ASPCA's advice, even the toughest tomcats should be kept indoors during the winter.
