A border collie herding sheep all day, a Labrador on a weekend of hunting and a terrier who walks around the block twice a day can all weigh about the same, yet their energy needs are very different. Fresh food plans portion packs from quiz answers about activity, but "very active" covers a huge range. This guide explains how to think about fresh food for active and working dogs, how to adjust portions as activity changes, and when to bring in your vet. It is general information, not veterinary advice; performance and working dogs in particular benefit from a vet who knows their workload.
What "active" really means
Fresh food quizzes usually ask you to choose an activity level such as low, moderate or high. Be honest and specific. A useful way to describe your dog to a vet or a food company:
- How many minutes of exercise per day, and what kind (walking, running, swimming, retrieving, agility).
- How intense it is: steady trotting or repeated sprints.
- Whether it changes by season, such as hunting season or summer hiking.
- Whether the dog works outdoors in cold weather, which adds energy needs for staying warm.
Many dogs described as "very active" by owners are actually moderately active. Truly working dogs, such as herding or sled dogs in season, can need far more calories than a typical pet.
Adjusting portions with activity
Calorie estimates start from resting energy needs and multiply by a factor for activity; see measuring resting energy needs basics. In practice:
- Start with the brand's suggested portion for the activity level you selected.
- Monitor body condition every couple of weeks rather than relying on the scale alone. Active dogs may gain muscle and lose fat at the same weight. See checking body condition on fresh food.
- Adjust portions gradually, often in small steps such as 5 to 10 percent, and reassess.
- Plan seasonal changes. A dog that hikes every weekend in summer and naps through winter may need different portions by season.
Ask the fresh food company how to change portions; many let you update activity level or adjust pack sizes in your account.
Calorie density and volume
Fresh food is high in moisture, so a dog with very high energy needs may need a large volume of food. Some very active dogs struggle to eat enough by volume, especially if they are excited or tired after work. If your dog is losing condition despite eating everything offered, talk to your vet. Options can include more meals per day, a more calorie-dense recipe or a different diet altogether. Our guide to reading calorie content explains how to compare density across foods.
Meal timing around exercise
Many vets and trainers recommend avoiding a large meal immediately before strenuous exercise, and waiting a while after hard exercise before a big meal. This is partly comfort and partly because of the risk of bloat (gastric dilatation-volvulus) in large, deep-chested breeds, which is a life-threatening emergency. Common practical habits:
- Feed the main meal a few hours before or after hard activity rather than right before.
- Split daily food into two or more meals on heavy activity days.
- Offer water regularly, but avoid huge gulps right after intense exercise.
Ask your vet for advice specific to your dog's breed and history, especially for breeds at higher bloat risk.
Long days in the field
On long hikes, hunts or competition days, you may need to carry food. Fresh food needs to stay cold, which is harder than carrying kibble or treats:
- Use an insulated bag with ice packs for a midday meal; see packing fresh dog food for day trips.
- Some owners carry a small amount of a shelf-stable food or approved treats for energy during the day, and feed the fresh meal at home or camp.
- Bring a collapsible bowl and enough water for the dog as well as yourself.
Hydration
Active dogs lose water through panting and, in hot weather, can overheat quickly. Offer water frequently in small amounts, rest in the shade and avoid heavy exercise in the hottest part of the day. Fresh food adds some water to the diet, but it does not replace drinking. Signs of overheating include heavy panting, drooling, weakness, stumbling, bright red gums or collapse. Heatstroke is an emergency; cool the dog and get to a vet immediately.
Tracking activity
A GPS collar with activity tracking can help you see how much exercise your dog actually gets across the week, which is useful when discussing portions with your vet. See using GPS collar activity tracking and GPS collars for hiking and rural areas.
Rest days and off-season
When activity drops, during injury recovery, after a season ends or in bad weather, reduce portions to match. Many active dogs gain weight in the off-season simply because portions stayed at work-season levels. Updating your plan when activity changes is one of the easiest ways to keep condition steady.
Signs to discuss with your vet
- Weight loss or visible ribs and hip bones despite eating well.
- Lack of stamina or slow recovery after exercise.
- Changes in stool quality during heavy activity.
- Limping, stiffness or reluctance to work.
- Any digestive upset around exercise.
Keeping a simple log
For dogs whose activity swings a lot, a log makes portion decisions easier. Each week, note total exercise (or the weekly figure from a GPS collar), the daily portion fed, weight if you weighed, and a quick body condition note. After a few months you will see how your dog responds to changes in workload, which helps you adjust the plan before the next season rather than after condition has already changed.
Common questions
Should active dogs eat a "performance" recipe?
Some foods are formulated for high activity or all life stages, which may suit active dogs. Whether a specific recipe suits your dog is a question for your vet. Look for the nutritional adequacy statement; see the AAFCO statement explained.
Can I feed extra treats on workout days?
Training treats on active days are common, but count them toward daily calories, and keep them in proportion.
Do active dogs need supplements?
A complete and balanced diet is formulated to meet nutrient needs without supplements. Some working-dog owners use joint or other supplements; ask your vet before adding anything, since extras can unbalance a diet or interact with medications.
