I have lived in a warm country all my life and had my pets here. I currently have 2 pomeranians (5yo, 4kg and 4yo, 6kg). By warm I mean: In summer, around 30 degrees Celsius, up to 40. In winter, around 10 degrees, minimum of 5, no snow, usually sunny sometimes with some rain. No snow at all.
Now I am moving to Stockholm, with its harsh (to my standards) winters and I have no idea how to deal with winter.
They will be inside during the vast majority of their days, but what are the most important things to have (I saw some dogs wearing boots during my research), notice and do so my dogs have a comfortable winter while still playing outside and having their daily walks? How long can we take them for a walk in cold days? (can we take them to a walk around the city center, for instance?)
