Rottweiler
Also known as: Rottie, Rottweiler Metzgerhund
A confident, deeply loyal German guardian with a calm, steady temperament and a profound devotion to its family. Powerful yet gentle with those it loves, the Rottweiler thrives with engaged, active owners who enjoy training and reward a dog that gives everything in return.
Origin and purpose
The Rottweiler descends from drover dogs the Roman legions brought across the Alps, which settled around the German town of Rottweil where they drove cattle to market and guarded the butcher's money purse. As droving declined the breed found new work in police, military and search roles, and the modern standard was fixed by German breed clubs in the early 20th century.
Temperament
Well-bred Rottweilers are described by breed authorities as calm, confident and courageous, deeply bonded to their family and naturally reserved with strangers rather than nervy or sharp. Like all guardian breeds they need early, ongoing socialisation and clear, reward-based training. Remember that breed is only a weak predictor of an individual dog's behaviour — research finds breed explains only about 9% of behavioural variation (Morrill et al., Science 2022) — so always assess the individual dog and its upbringing, not the label.
Health and longevity
As a large, fast-growing breed the Rottweiler carries several heritable health conditions. Buy from breeders who screen hips, elbows, heart and eyes.
Common health conditions
Exercise and heat
The Rottweiler's short black coat absorbs solar heat. In hot climates, walk during the cooler parts of the day, avoid hot pavement, and ensure shade and water are always available.

Climate & exercise in Osaka
Osaka is humid subtropical; one of Japan's hottest cities in summer (July–August avg 36–37°C peak); typhoon season Aug–Oct; mild winters; Osaka's concrete density intensifies the urban heat island effect. walk before 6:30am or after 7pm in July–September; Osaka's heat island effect keeps night temperatures high — pavement can exceed 50°C at midday in summer. Osaka summers are consistently the hottest of Japan's major cities. Heatstroke risk is extreme in July–September; flat-faced breeds (French Bulldog, Pug, Shih Tzu) are critically at risk. Osaka's Dotonbori and Namba areas trap heat — avoid walking dogs through central commercial districts in summer afternoons.
Parasite prevention
Plan for Heartworm prevention essential May–November (mosquito-season window in Kansai); tick prevention recommended for dogs accessing Minoh Park, Kongo-Katsuragi Quasi-National Park, Rokko Range and Ikoma hills year-round.
