With the cold weather coming soon. I start looking at new foods. Foods that are high in fat and oils. This is for both me and my dogs.
We have seen that most dogs that live in very cold conditions have a very fatty and oily diet, this is because oils and fats hep keep the coat and skin well hydrated and insulated. It also stimulates new hair growth and a thicker coat for the winter will help your dogs more then you may think.
In the summer i feed a very large poultry diet and maybe some Dutch and lamb every now and then. Withthe winter coming i slowly increase the land and add fish to their diet. Salmon is a great prep for the winter and offers the dogs great support for the winter.
It is also very important to look after he joints as the temperature decreases, especially in older dogs or your working breeds.
Go to your food specialist and ask them what to do for your breed and how to look after them for the winter.
