Keep your pet at a healthy weight throughout the winter. Some pet owners feel
that a little extra weight gives their pet some extra protection from cold, but
the health risks associated with that extra weight don’t make it worth doing.
Watch your pet’s body condition and keep them in the healthy range. Outdoor pets
will require more calories in the winter to generate enough body heat and energy
to keep them warm – talk to your veterinarian about your pet’s nutritional needs
during cold weather.
