Size

5′6″ person 17–19″ at shoulder

Exercise & training

Exercise. Moderate: daily walks and active play, such as a game of fetch. Puppies do better with several short sessions than one long walk, and older dogs need gentler outings.

Training. Trains at an average pace. Reward-based methods and a regular routine work best.

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 980–1,500 kcal for a healthy adult
Dry food
Roughly 2.5–3.75 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

Typical lifespan is 12–14 years. Conditions reported in the breed:

Allergic skin diseasehip and elbow dysplasiademodicosis

Ask breeders for health-test results from the parents (hips, eyes, and DNA tests where relevant), and schedule yearly vet checkups.
