Diet and nutrition
An active working dog needs good-quality food suited to its workload.
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.
- A dog is at the right weight when you can feel its ribs without pressing hard.
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.
