What to give a dog before a competition? A guide for sporting and working dogs

The hours leading up to a competition or a demanding working day are usually filled with routines: checking the equipment, making sure everything is ready, warming up the dog… and yet the question of what to feed the dog or which supplement to give before exercise is often answered almost intuitively, without much thought behind it. It is a topic that deserves more attention than it usually receives, because what a dog has available in its body immediately before competing can make a real difference to its performance.

The goal: full reserves, not a full stomach

First of all, it is worth clarifying a common misconception: feeding a large meal before competing is not the same as nutritionally preparing a dog for exercise. A substantial meal immediately before physical activity can cause digestive discomfort, heaviness or even more serious problems depending on the type of activity and the breed. What really matters is ensuring that the body has the nutrients it will need during exercise, without placing a heavy digestive load on the dog immediately beforehand.

This means thinking of nutritional preparation not as something that happens only in the hours before an event, but as a process that starts days or weeks in advance, with a diet adapted to the dog’s physical demands, and is completed in the final hours with a targeted nutritional boost designed to maximise nutrient availability at the key moment.

What does the body need immediately before exercise?

During intense exercise, the body draws on several resources at once: it needs readily available energy, good muscle oxygenation and systems that help counteract the physiological stress caused by exercise. This is where several nutrients with specific roles come into play.

Iron and copper are key to red blood cell production and to ensuring that oxygen is transported efficiently to the muscles. B vitamins, particularly B1, B2, B6 and B12, are directly involved in cellular energy metabolism, helping convert available energy into actual physical performance. Vitamin C helps improve iron absorption and also provides relevant antioxidant support against the oxidative stress generated by intense exercise. Minerals such as zinc and manganese, together with L-carnitine, complete a nutritional profile designed to support muscular effort in the short term.

Targeted support for the right moment

To address this specific window — the hours immediately before competition — there are formulas designed to be administered at a very precise point in the process. This is the case with MEGATOP™ Event (product page link), a multivitamin and multimineral oral paste rich in iron, copper and vitamins B2, B6 and B12, designed as targeted support for sporting and working dogs. Its recommended use is specifically designed for this purpose: it is administered the night before the event and, for additional support, the dose can be repeated two hours before the competition.

It is a product designed for this very specific moment immediately before physical exertion, rather than for continuous daily use, unlike other supplements intended to provide nutritional support throughout the season. It is therefore important to understand that its role is targeted support, as part of a nutritional preparation strategy that should begin well in advance.

Hydration: the often-overlooked factor

No matter how well planned the nutritional strategy is, it will be of limited benefit if the dog is not properly hydrated before competing. Even mild dehydration reduces the body’s ability to regulate temperature and directly affects muscular and cardiovascular performance. Ensuring that the dog has access to fresh water in the hours before the event, and that water remains available during competition breaks whenever the discipline allows it, is just as important as any supplement.

Every dog and every discipline is different

There is no single formula that works for every dog. An agility dog, a long-distance canicross dog and a hunting dog spending the day working in the field have different needs, both in terms of energy requirements and the timing of any additional nutritional support. Therefore, beyond general recommendations, the most sensible approach is to adapt the strategy to the specific discipline, the dog’s history and, when in doubt, the advice of the veterinarian or physical trainer who knows the animal best.

Being well prepared for a competition does not depend on a single last-minute action, but on a series of decisions made well in advance: appropriate training, a diet adapted to the demands and, when necessary, targeted nutritional support at the right moment.
