Mastiff & Bullmastiff Adoption in Perth

Mastiffs are not a restricted breed in WA

The word “mastiff” makes some Perth adopters nervous about the law, so it is worth clearing up first. The English Mastiff and the Bullmastiff are legal to own, register and rehome across WA under the Dog Act 1976. Neither is on the restricted list.

WA restricts five specific breeds, which are prohibited from import into Australia and cannot be sold, bought or given away: the American Pit Bull Terrier, Dogo Argentino, Fila Brasileiro, Japanese Tosa and Perro de Presa Canario. A restricted-breed dog must be sterilised, muzzled and leashed in public, and kept in an approved enclosure. That is the legal reason you will never see one of those five on a WA adoption list. The Mastiff and Bullmastiff carry none of those conditions. The plain-English rules for WA dog owners are set out by the Department of Local Government, Sport and Cultural Industries.

Why Mastiffs end up in Perth rescue

Understanding why these gentle giants reach rescue is the best preparation for adopting one, and the reasons are almost always about the scale of the dog rather than its temperament.

Underestimated size and space. A Mastiff puppy grows into an enormous adult, and the space it needs indoors and out, the strength required to handle it on a lead, and the sheer presence of a 60 kg dog in the home catch owners off guard. A giant dog does not fit every home.

Cost. Everything scales with the size. A Mastiff eats a lot, and giant-breed veterinary care, larger medication doses and any surgery all cost more than for an average dog. Owners who did not budget for a giant breed can find the ongoing cost unmanageable.

Housing. Many rentals and strata schemes are wary of giant guarding breeds, so an owner who moves into a place that will not accept the dog sometimes has to surrender out of necessity rather than choice.

The drool, and the short lifespan. Mastiffs slobber, which surprises some owners, and the breed's short lifespan and the cost and heartbreak of giant-breed health problems play a part in surrenders too.

The dogs themselves, when well raised, are gentle, calm and devoted. What a rescue Mastiff needs is a home genuinely built for a giant guardian, with the space, experience and budget the breed requires, not a different temperament. Ask the rescue about the dog's temperament, its socialisation history, and how it is with people and other animals.

Where to adopt a Mastiff in Perth

A handful of shelters and rescues account for most of the giant breeds in the Perth pipeline. They differ in style (large metro shelter versus foster-based rescue) and in process. Mastiffs come through less often than Staffies, so set up alerts on every rescue you would consider. Fees and current availability change, so check each site directly.

There are smaller WA rescues too, often run by volunteers out of foster homes, and giant-breed dogs sometimes come through them. A quick way to see many rescues at once is PetRescue, a national aggregator that lists animals from hundreds of member rescues in one searchable place. Whatever the source, verify any rescue through a real address, a current adoptable-dog list and charitable status before sending money. Browse the current Mastiffs, Bullmastiffs and mastiff crosses on the Perth Mastiff listings.

What a Mastiff costs to adopt and keep in Perth

The adoption fee runs about $300 to $600 for an adult Mastiff and $400 to $800 for a puppy, and it already includes desexing, vaccination, microchipping, worm and flea treatment and a vet check, which would cost far more if you paid for them separately.

The real cost of a Mastiff is the ongoing one, because everything scales with the size. Budget for council registration (a sterilised, microchipped dog gets a reduced fee, set by your local council rather than a single Perth-wide figure), secure fencing, and a strong harness and lead. Then plan yearly costs toward the higher end, roughly $2,500 to $3,500, because a giant dog eats a lot and giant-breed veterinary care, larger medication doses and any surgery all cost more. Because the breed carries real health risks, pet insurance taken out while the dog is young is genuinely worthwhile. Register once the dog is 3 months or older, and check your council's current fee via the WA Government dog ownership hub.

The giant-breed health picture

A Mastiff is a wonderful dog, but adopting one responsibly means going in with eyes open about giant-breed health. None of this is a reason not to adopt. It is a reason to keep the dog lean, insure it young, and know your nearest emergency vet. Always take medical decisions with your own vet rather than acting on a checklist.

Bloat (gastric dilatation-volvulus). The single most urgent giant-breed emergency. A deep chest can twist on itself, cutting off blood flow, and it is fatal within hours without surgery. Learn the signs: a swollen, tight belly, unproductive retching, restlessness and distress. If you see them, get to an emergency vet immediately. The RSPCA Australia Knowledgebase is a good plain-English starting point on prevention and warning signs.

Hip and elbow dysplasia and joint disease. Giant breeds carry a higher burden of developmental joint problems, and the weight makes any joint issue harder on the dog. Responsible breeders screen for hips and elbows through databases such as the Orthopedic Foundation for Animals, though with a rescue dog you rarely have that history, which is another reason to keep the dog at a healthy weight and manage exercise. Do not over-exercise a growing puppy, because it damages developing joints.

Cancer and a short lifespan. Giant breeds age fast and have an elevated lifetime cancer risk, and a Mastiff commonly lives only 7 to 10 years. Prompt veterinary attention to any new lump or change is worth it. The Australian Veterinary Association is a useful guide to finding a vet and thinking about preventive care.

Heat sensitivity. A large, heavy, often dark-coated dog struggles in the Perth summer more than most breeds, which brings us to the WA-specific safety section below.

Keeping a Mastiff safe in Perth: heat, snakes and 1080

Perth has a Mediterranean climate, with hot dry summers and mild wet winters. For a giant, heavy-coated guardian, three safety habits matter more here than the tick worry people bring over from the east coast.

Summer heat and hot ground. Perth summers run long stretches in the mid-30s to 40°C. A big, heavy Mastiff overheats faster than a lean dog, and the risk is real. Walk in the cool of early morning or late evening, carry water, and use the back-of-your-hand test on the pavement or sand first. If it is too hot for your hand, it is too hot for paws. Never leave a dog in a parked car. Heatstroke is an emergency: get to a vet immediately.

Snakes. Dugites, gwardars and tiger snakes are common around Perth's bushland corridors, wetlands and the Swan and Canning river foreshores, and bites spike in the warmer months from roughly September to April. A curious dog that disturbs a snake can be bitten, and a bite from these highly venomous species needs an emergency vet fast. Keep your dog on lead and out of long grass on warm-weather walks.

1080 baiting. Fox and feral-cat baiting with 1080 (sodium fluoroacetate) runs across many WA reserves, forests and bushland under the state Western Shield program. The WA Government advises that all baited areas must be treated as dangerous to pet dogs at all times, and 1080 is lethal to dogs, including through a poisoned carcass. Watch for “1080 POISON RISK” signage, keep your dog leashed and under control in reserves, and know your nearest 24/7 emergency vet before you head out.

Perth's round-the-clock emergency hospitals include Perth Vet Emergency at Cannington, The Animal Hospital at Murdoch University, and WAVES at Success. On paralysis ticks, WA is the opposite of the east coast: the paralysis tick is not established here, so the local risk is low. The one time to think about it is before you travel east to the Queensland, NSW or Victorian coast, when you should ask your vet about tick prevention. For general parasite prevention (fleas, worms, heartworm), your vet will recommend a routine product.

What a Mastiff is like to live with

For a prepared owner, a well-raised Mastiff or Bullmastiff is a magnificent companion. They are famously gentle, calm and steady, deeply devoted and affectionate with their family, and often patient and loving with their own children. They are low-energy indoors, content to be a large, warm presence at your feet, and they are natural guardians, watchful and aloof with strangers while soft as anything at home. The Bullmastiff was developed as a gamekeeper's night dog, bred to be brave and protective but under control rather than aggressive, and the English Mastiff shares the same steady guarding character.

The other side is everything that comes with a giant guardian: the space, the strength, the cost, the drool, the heat sensitivity, and the socialisation and training a powerful dog needs. This is a dog for a committed, experienced household with room, not for someone wanting a low-cost, low-effort or apartment pet. Match the breed to your genuine situation and a rescue Mastiff will repay you with years, however precious and few, of gentle, devoted companionship.
