A menu for every age
Needs change over time
Puppy : A growth diet for a medium-sized puppy helps support bone and muscle development without excess energy.
Adult : The ration must be adjusted to the actual activity level, particularly in dogs used for hunting or very athletic.
Senior : With age, a more digestible diet and careful monitoring of weight and joint comfort become priorities.
Which food?
Kibble, wet food, or home-cooked diet?
Premium complete kibble for an active medium-sized dog often provides a practical and consistent base, with a composition rich in quality animal proteins and well-balanced lipids. The exact choice must remain adjusted to the age, actual energy expenditure, possible neutering and the dog's digestive tolerance.
Amounts
How much should you give?
The daily quantity must be adjusted according to weight, activity, season and the type of food chosen, because needs vary greatly between a companion dog and a very active subject. A visual monitoring of the silhouette and stools helps to fine-tune the ration with the veterinarian if needed.
| Weight | Daily amount | Meals/day |
|---|---|---|
| 20 - 23 kg | 343 - 471 g | 2 |
| 23 - 27 kg | 390 - 535 g | 2 |
| 27 - 30 kg | 436 - 598 g | 2 |
Change
Managing the food transition
Any dietary transition must be done gradually over several days in order to limit digestive upsets. In an active dog like the Griffon Korthals, it is preferable to avoid sudden changes, especially during hunting periods, sustained exertion or stress.
Hydration
Water: do not overlook it
Clean, fresh water must remain available at all times, with increased vigilance after exercise, in hot weather and during prolonged outings. Good hydration contributes to recovery and to maintaining the performance of this hardy dog.
Little extras
Treats, in moderation
Treats can be useful for training and recall, provided they remain simple, digestible and counted in the daily intake. In this dynamic breed, they must not make up for a lack of activity or unbalance the main ration.
Good habits
For a top-notch bowl
- Split the daily ration into at least two meals.
- Avoid intense exertion just before and just after the meal.
- Adjust the ration to hunting periods or sustained activity.
- Regularly monitor the body shape rather than relying solely on appetite.
Never give
As with other dogs, you should avoid in particular chocolate, onion, garlic, grapes, avocado, alcohol, cooked bones, xylitol and very fatty or salty foods, as they can cause poisoning, severe digestive disorders or neurological and kidney damage.
