How do dogs' energy requirements change in winter?

When temperatures drop, our dogs' metabolism also changes. While we bundle up in warm clothes, a dog's body has to work to stay warm – and that takes energy. Many owners underestimate just how much their dog's energy needs can increase in winter.

Why dogs need more energy in winter

Thermoregulation, the maintenance of body temperature, is one of the body's biggest energy consumers. If the outside temperature drops, the calorie requirement automatically increases.

• Heat retention: Dogs with little undercoat, in particular, need energy to keep their bodies warm.
• Cold resistance: Nordic dogs have good insulation, but they also burn more calories in winter.
• Exercise: Snow and cold stimulate many dogs – and exercise consumes additional energy.
• Muscle work: Cold weather challenges the metabolism, the muscles work harder.

On average, energy requirements increase by 5–20% , and even more in very active dogs.

Which dogs are particularly affected

• Short-haired breeds (e.g. Dalmatian, Whippet, Doberman)
• Small breeds that cool down faster
• Senior dogs , whose metabolism is less flexible
• Young, very active dogs who play outside a lot.
• Underweight dogs that have less energy stored

How owners can support winter needs

• Adjust portion size moderately
• Choose high-quality, easily digestible energy sources
• Provide additional energy through functional snacks
• Keep an eye on the dog's weight (ribs should remain palpable)
