One day the dogs will make us pay for this.
Slightly off topic, but folks with pets may appreciate PetEdge for their pet-related needs. My mother-in-law turned us on to them. They are a wholesaler that will sell online to individuals. Pretty hefty delivery fees, but if one buys a lot of stuff the price breaks are worth it. I do not work for PetEdge, and have no interest in them other than my wife and I are fond of their service.
BTW, I have to agree with JG. Many small dogs, especially those with short hair, should NOT be outside in cold weather for very long. While the products in the posted link are silly beyond belief, short-haired dogs should always have some sort of warm cover for cold weather. I am reminded of my neighbour recently as he walked his short-haired dog in front of our house with a jacket on. We told him Pete (the dog) looked quite nice in his jacket and he replied, "My dog has fleece." Bad pun, but we laughed in spite of ourselves.
Just let the dog tell you if he/she is cold or not.
