Living with a Mastiff (English) in Australia
The English Mastiff holds the weight records — the heaviest dogs ever recorded — yet the temperament is pure nanny: patient, sensitive and devoted. They’re surprisingly good house dogs for their size, needing only modest exercise and a reinforced couch. The arithmetic is the catch: giant-breed everything (food, medication, insurance), drool, and 7–10 years together. Australians in hot climates should think hard — these dogs melt in summer and need genuine cooling.
Health watch-outs
The giant-breed list, at maximum scale:
- Hip and elbow dysplasia — scored parents are essential.
- Bloat and heart disease — feeding care and screening matter.
- Cystinuria — a breed-relevant urinary condition; DNA testing exists.
Budget at a glance
- Puppy price: typically $2,500–$4,500 from a registered breeder — much lower offers are often scams.
- Insurance: around $80–$140/month — see our pet insurance cost guide for what shapes premiums.
- The single most expensive size category: expect top-end food, insurance and medication costs.
