Exercise & training
Exercise. Energetic: needs real exercise every day, such as long walks, hikes or running games. Puppies do better with several short sessions than one long walk, and older dogs need gentler outings.
Training. Eager and responsive. Picks up basic manners quickly and enjoys learning tricks.
Grooming
Short, smooth coat: a weekly once-over with a rubber curry mitt or bristle brush and an occasional bath. Light shedding.
For every dog: trim nails when you can hear them click on the floor, brush teeth daily if you can (a few times a week still helps), and clean ears about once a month, drying them well after baths and swims.
Diet & feeding
- Daily calories
- About 1,310–1,770 kcal for a healthy adult
- Dry food
- Roughly 3.25–4.5 cups a day at ~400 kcal per cup
Puppies eat four small meals a day at 6 to 12 weeks, drop to three somewhere between 3 and 6 months, and move to two meals a day from about 6 months.
Large-breed puppies can take 15 to 24 months to finish growing. Ask your vet about a large-breed puppy food, and check before adding any supplements.
Deep-chested dogs are at higher risk of bloat (GDV). Feed two meals a day rather than one, use a slow feeder if your dog gulps, and keep mealtimes calm.
Keep treats, including training treats and table scraps, under 10% of daily calories.
Calories use the resting-energy formula from the Merck Veterinary Manual (70 × body weight in kg0.75) times a maintenance factor of 1.4 to 1.8, so very active or working dogs may need more. Cups assume about 400 kcal per cup; check your food's label. Treat any feeding chart as a starting point and adjust to body condition.
Health
