Facts and myths ![](https://bellywelly.eu/files/BW-ARTICLE-IMG/web/Kalorie%20zim%C4%85_web-1.jpg) During winter, many owners ask themselves the same question: should my dog ​​or cat eat more because it's cold? Many myths have arisen around this topic, often leading to overfeeding, and consequently, obesity and health problems. So let's examine what's true and what's just common opinion. **Myth 1: Every animal needs more calories in winter.** This is one of the most frequently repeated myths. Not every animal needs more energy in winter. Calorie requirements depend not on the season, but on activity level, living conditions (house, apartment, yard), age, health, breed, and body weight. An indoor dog that goes on shorter walks and exercises less in winter often needs fewer calories, not more. The same is true for an indoor cat that spends the winter months primarily napping. **Fact: Pets that are outside burn more energy.** The situation is completely different for animals living outdoors, working dogs, or very active dogs in winter (e.g., long walks, running, sports).  The body then uses more energy to maintain a constant body temperature, so in such cases, increasing the caloric content of the diet may be justified. However, it's important to do this wisely – through quality food, not just larger portions. **Myth 2: A thick layer of fat protects against cold.** Many owners believe that "a little more weight" will help their pets survive the winter. This is a misconception. Being overweight doesn't protect against the cold; instead, it puts strain on joints, weakens immunity, and increases the risk of metabolic diseases.  Natural protection against the cold comes from a coat and a well-balanced diet, not excess body fat. **Fact: The composition of your winter diet is more important than the number of calories.** In winter, the quality of food, not necessarily the quantity, is crucial. The diet should provide high-quality protein (for regeneration and immunity), contain an adequate amount of fat (for energy, skin and coat condition), and be rich in vitamins and trace elements.  In practice, it's often better to switch to a more nutritious food rather than increasing the current portion. **Cats in winter – a special case** Cats, especially indoor cats, tend to reduce their activity levels in winter. Shorter days and fewer stimuli contribute to weight gain. Calorie increases are rarely necessary, and portion control, hydration, and stimulating exercise through play are more common. **Dogs in winter – an individual approach** The differences in dogs are much greater. A small, couch potato and an active, large-breed dog have completely different needs. In winter, it's worth observing your dog rather than relying on a calendar. If your dog is losing weight despite eating normally, is freezing quickly, or is very active, then you might consider modifying its diet. However, if it's gaining weight, it's a clear sign that it's over-calorieing. **How can you tell if your pet needs more energy?** Instead of guessing, it's worth paying attention to changes in weight, coat condition, energy levels, and appetite. Regular monitoring and consultation with a veterinarian or animal nutritionist is the best approach, especially for older animals or those with chronic illnesses. Winter doesn't automatically mean your dog or cat should eat more. For most pets, the quality of their diet, not its calorie content, is key. Increasing energy intake only makes sense when the body's needs actually increase. Conscious winter feeding isn't about "filling the bowl," but rather adapting the diet to your pet's actual needs – and that's the best way to ensure year-round health.
