She is really too old to be living outside. She is a senior dog and living outside could help shorten her life span. It is a lot of work for a dog to keep warm in the winter, extra calories are needed not to mention proper shelter. And if she does not use a dog house or shelter for some reason, depending on how cold it gets there (my conversions from Farenheit to Celcius is not that great) she could freeze to death. I live in Virginia, USA and though considered MidAtalntic to Southern region, we have been averaging about 25 – 29 F at night. Anyhow, your dog needs several things: 1) A weather proof shelter. No leaks, no drafts and raised a few inches off the ground. It should be facing away from prevailing winds, have a door flap and ideally, the best dog houses for outside I have seen are L-shaped or U-shaped inside so the dog can get around a corner and away from door drafts. 2) Bedding that is changed at least once a day. Damp bedding (even those outdoor mats can get damp) holds no heat and can make the dog have to work harder to keep warm. The bedding should be thick and heavy so the dog can snuggle down. Just a blanket will not be enough. Straw covered with a couple heavy blankets will help. Or you can actually buy heated dog beds for use in outdoors shelters. But the dog needs something it can snuggle down into that will help hold body heat. Just a blanket will not do that. 3) Feed a perfromance level food and give two meals a day. A dog will need the extra energy and calories, etc in this food for winter life. 4) Water freezing and dehydration are serious concerns in the winter. The air tends to be drier and dry air can lead to increased risk of dehydration just as heat can. So you will need to ensure that the water does not freeze (there are heated outdoor water buckets you can buy) or make sure you go out three or four times a day and offer fresh water. Also, add warm water to her kibble at meal times and this will get more fliud into her. 5) Health, the cold and cold and damp will have an affect on aging joint, can worsed the effects of arthitis, etc. Also, you have to watch for weight loss, underweight dogs have a harder time staying warm. Dogs with matts or tangles do not stay as warm as they do not hold heat. Also, your dog is a breed not really bred for total life outside. Hope this helps.
