We keep the house @ 65 degrees. Usually during the day they're o.k. I check their ears and paws and if they seem cool I do put a tee shirt or Jammies on them on cold nights. When I take them out I always have a jacket or sweater on the Yorkie. Baron is only 7 pounds. My Papillion, Sammy is a teapot @ 15 pounds and does have more hair and insolation than Baron!! Hope this helps...
