Dachshunds getting exercise on a cold wintry day

It was a very cold and windy day, and young dogs needed exercise. With the wind chill of -3F (-19.5C) I was not willing to take multiple trips so I let Paika, Bella (first row) and Summer and Sky (second row) go together. The picture was taken just after I had let them out of our gated yard to the field. They were crowded by the gate waiting for me to open it and when I did it, they ran in one direction (where usually rabbits are). This is why they are so close together, and obviously Paika and Bella took the lead (as they are older, bigger and faster).
