A menu for every age
Their needs change as they grow
Puppy: A large-breed or giant-breed puppy diet is essential to support slow, steady growth without excess energy.
Adult: The adult needs a ration adapted to its actual weight, its activity, and its body condition, ideally split into two meals.
Senior: In older dogs, a more digestible diet better adjusted to activity helps preserve muscle mass without overloading the joints.
Which food?
Kibble, wet food, or homemade meals?
Premium kibble formulated for large or very large dogs generally suits well, with a moderate energy density and a good mineral balance. A home-prepared ration can also be considered if it is formulated with a professional to properly cover its needs.
Portion sizes
How much should you feed?
Quantities vary greatly depending on age, sex, weight, sterilization, activity level and the type of food chosen. In the Leonberger, it is particularly important to adjust the ration during growth to protect the skeleton and avoid excesses.
| Weight | Daily amount | Meals per day |
|---|---|---|
| 55 - 65 kg | 600 - 750 g | 2 |
| 65 - 80 kg | 750 - 900 g | 2 |
Changing food
How to switch foods successfully
Any dietary change must be made gradually over several days in order to limit digestive upsets. In a giant dog, a gentle transition also helps to preserve intestinal comfort and appetite.
Hydration
Don't overlook water
Clean, fresh water must remain available at all times. Good hydration is essential, especially in hot weather, after walks and for dogs fed mainly with dry food.
A little extra
Treats in moderation
Treats should remain occasional and included in the calculation of the daily ration. It is better to favor simple, digestible rewards to avoid an unnecessary caloric overload in this large dog.
Good habits
Make mealtimes count
- Split the daily ration into at least two meals.
- Avoid exercise before and after meals.
- Weigh the rations regularly to limit excess.
- Closely monitor growth during the first two years.
Never feed these foods
As with other dogs, it is necessary to avoid in particular chocolate, onion, garlic, grapes, avocado, cooked bones, alcohol, xylitol and very fatty foods, as they can cause digestive, neurological, hematological disorders or severe poisoning.
