They love children but they dont love hot weather. I live in bosnia on the sea and they don't enjoy the hot weather.
Tornjak don't support the heat so well. They love the snow, and are said to be able to sleep comfortably in the snow due to their thick fur. They are generally relatively calm and non aggressive, and suitable for children; they are very intelligent. However, they need enough space and outdoor exercise and some training by a qualified person will be most helpful, because they tend to be somewhat willful. For a smaller child they might be a little difficult to handle due to their size and strength.
