Tips for a healthy diet

The table gives a starting estimate, calculated with the formula from the Merck Veterinary Manual. The first two calorie columns show the calories per day for a healthy adult dog. The last column shows what this means in dry food with 3,500–4,000 kcal per kilogram.

Dog's weight Calories per day (neutered) Calories per day (not neutered) Dry food per day (approximate)
20 kg 1,060 kcal 1,190 kcal 260–340 g
27 kg 1,330 kcal 1,490 kcal 330–430 g
35 kg 1,610 kcal 1,810 kcal 400–520 g
  • Split the food into two meals a day.
  • Do not let it run right after a meal.

Foods to avoid

Some human foods are dangerous for dogs: chocolate, coffee, grapes and raisins, onions, garlic, xylitol (a sweetener used in chewing gum), macadamia nuts and alcohol.

Reproduction and development

Physical and emotional maturity

In dogs, sexual maturity usually comes between 6 and 12 months. Most breeds become adults at around 13–15 months.

Mating and pregnancy

Pregnancy lasts about 63 days, counted from ovulation. Mating a female on her first heat is not recommended. The FCI standard requires that only healthy dogs of typical breed appearance are used for breeding.
