The short answer
You can adopt a Bullmastiff in Perth, but be patient and honest with yourself. This is a large, powerful guardian breed for experienced owners, not a first dog. Purebreds are uncommon in rescue, so set alerts across Dogs' Refuge Home WA at Shenton Park, RSPCA WA at Malaga, the foster-based SAFE Perth and SAFE, and PetRescue, be application-ready, and stay open to a cross or an older dog. Adoption runs about $600 for an adult, all-inclusive, against several thousand dollars from a breeder, and the breed is not restricted in WA. The Bullmastiff needs early socialisation, steady reward-based training, your company, and careful heat management in summer. Meet those needs and you have one of the most devoted guardians there is.
Why Bullmastiffs end up in Perth rescue
People take on the presence, then meet the reality. A Bullmastiff is an imposing dog, and plenty are taken on for security or image without a clear picture of what the breed needs. Underneath the look is an intelligent working guardian that needs steady handling, extensive socialisation and real commitment.
Size and the guarding instinct. A Bullmastiff at fifty-plus kilos, coming into its protective instinct, is a serious dog that needs its owner to have done the socialisation and training. When that work did not happen, you get a large, strong, under-taught guardian that is genuinely hard to manage, and that is a common path to surrender.
Housing and life changes. Housing is a real pressure in Perth, where many homes are rented or under a strata or body corporate scheme that will not take a giant guardian breed, so a move can cost an owner the dog. Add a relationship breakdown or an owner who could not keep up, and a steady number reach rescue. Crosses appear too, often blended with other mastiff or bulldog types.
What this means for you. A Bullmastiff in rescue is rarely a broken dog. It is usually a good guardian whose size, strength or need for training outran its last home. If you have experience with large or guardian breeds and can commit to socialisation, training and heat-safe management, you are looking at a wonderful adoption.
Where to adopt a Bullmastiff or Bullmastiff cross in Perth
Because Bullmastiffs are uncommon in general rescue, a wide alert net is the right approach. Set listing alerts on every rescue you would consider, and add large-dog and guardian-breed foster networks. Expect a careful application process. For a fuller directory, see our Perth adoption resources hub.
1. Dogs' Refuge Home WA
A dogs-only, not-for-profit shelter at Shenton Park in inner Perth, running since 1935. Adoption includes desexing, vaccination, microchipping and a vet check, and large guardian types and crosses appear from time to time. Browse the current dogs at dogshome.org.au.
2. RSPCA Western Australia
The state welfare body, with its Animal Care Centre at 108 Malaga Drive in Malaga. Every animal is health- and behaviour-checked before it is listed, which matters a great deal for a large guardian because it gives you an honest read on how the dog is with people and other animals. Apply at rspcawa.org.au.
3. SAFE Perth and SAFE
Both run a foster-care model rather than a central shelter, so a Bullmastiff or cross lives in a home while it waits, and the carer's notes on temperament, training and guarding drive tend to be detailed and honest, which is exactly what you need to match a powerful guardian to the right household. SAFE Perth lists at safeperth.com.au and SAFE at safe.org.au. Confirm which organisation holds a given dog.
4. PetRescue
A national aggregator that lists Bullmastiffs and Bullmastiff crosses from many smaller WA rescue groups in one searchable place, at petrescue.com.au. It is the fastest way to scan many WA rescues at once.
Be wary of any group that asks for money before you have confirmed a real address, a current adoptable-dog list and registered status. Browse the current Bullmastiffs and crosses on the Perth Bullmastiff listings.
What a Bullmastiff costs: adopt versus buy
Adoption is far cheaper at the outset. A rescue fee for an adult Bullmastiff or Bullmastiff cross through a Perth rescue commonly runs about $600, with the rare puppy usually more, and that fee already covers desexing, vaccination, microchipping, worm and flea treatment and a vet check. A Bullmastiff from a breeder in WA, by contrast, often runs to several thousand dollars with none of that vet work done yet, so adopting is many times cheaper up front and the dog arrives already vetted.
Council registration is a separate legal step. Under the Dog Act 1976, a dog must be microchipped by 3 months and before it changes hands, and registered with your local council from 3 months, with a substantially reduced fee for a desexed and microchipped dog. Check the WA Government dog ownership hub and your own council for the current amount. The real cost of the breed is the ongoing giant-dog one: a lot of food, large-dog vet care, and professional training, which is strongly recommended.
Bullmastiffs are not restricted in WA
It is worth stating plainly, because people assume any big guardian breed is restricted. The Bullmastiff is not a restricted breed in Western Australia. Under the Dog Act 1976, only five breeds are restricted: the American Pit Bull Terrier, Dogo Argentino, Fila Brasileiro, Japanese Tosa and Perro de Presa Canario. The Bullmastiff is legal to own and to rehome normally, needing only to be microchipped by 3 months of age and before it changes hands, and registered with your local council from 3 months, with a reduced fee for a desexed and microchipped dog. The dangerous-dog framework under the Act applies to any breed by behaviour, so if a dog of any kind is involved in an attack or menacing behaviour a council can declare it dangerous, which triggers sterilisation, muzzling and secure-enclosure rules. That is a reason to take socialisation and secure containment seriously with a powerful guardian, not a breed-specific ban.

Plenty of people arrive here after searching for a Bullmastiff to buy, often drawn by the protection reputation. Reputable breeders exist, but before you spend anything know that the online market for popular guardian purebreds is scam-prone, and Bullmastiffs are a target. A cheap puppy, a deposit request for a dog you have not met in person, or a seller who will not show you both healthy parents is a warning sign rather than a bargain, and with a breed where early socialisation decides everything, a backyard breeder is the worst possible start. Scamwatch has documented deposit scams for puppies that do not exist.
WA does not run a Pet Exchange Register or a breeder supply-number scheme, so there is no source number to look up here. The practical safeguard is the microchip: a dog sold or given away legally in WA must be microchipped and registered, so ask to see the microchip paperwork before you pay anything. Adoption sidesteps much of that: it costs a fraction of a breeder price, gives a vet-checked dog a home, and an assessed adult asks far less guesswork about temperament than a puppy of a powerful guardian breed. The RSPCA Australia Knowledgebase has good guidance on choosing a dog and avoiding poorly bred puppies.
Adult or puppy, and how to choose
For almost every adopter an assessed adult is the more responsible choice, and Bullmastiff puppies are rare in rescue anyway. With a powerful guardian breed, seeing the temperament matters enormously: an adult has a known temperament the rescue can describe, an established size you can see rather than gamble on, often some training in place, and a lower adoption fee. Read the foster carer's notes closely, because how a specific dog does with children, other dogs, visitors and being left alone predicts the fit far better than the breed average. Older, settled Bullmastiffs often wait longest and make the steadiest match for an experienced adopter.
Frequently Asked Questions
Where can I adopt a Bullmastiff near me in Perth?
Start with the main Perth shelters and rescues: Dogs' Refuge Home WA at Shenton Park, RSPCA WA at Malaga, and the foster-based SAFE Perth and SAFE. Purebred Bullmastiffs are uncommon in rescue, so Bullmastiff and Mastiff-type crosses show up more often than full purebreds. Set listing alerts across every rescue you would consider, have your application ready, and stay open to a cross or an older dog. PetRescue lists dogs from many smaller WA rescues in one place. Rescues assess big guardian dogs carefully, so expect a thorough process.
Why do Bullmastiffs end up in rescue?
Almost always because someone took on more dog than they were ready for. The Bullmastiff is a large, powerful guardian breed, and plenty are bought for protection or presence without the owner grasping the size, strength, socialisation and training it needs. A Bullmastiff reaching adolescence at fifty-plus kilos, coming into its guarding instinct, is a serious dog that needs the training to have been done. Housing is another driver in Perth, where many homes are rented or under a strata scheme that will not take a giant guardian breed. Others reach rescue after a life change. The temperament is often intact; most just needed an experienced owner.
How much does it cost to adopt a Bullmastiff versus buy one?
Adoption is far cheaper up front. A rescue fee for an adult Bullmastiff or Bullmastiff cross through a Perth rescue commonly runs about $600, with the rare puppy usually more, and that fee already includes desexing, vaccination, microchipping, worm and flea treatment and a vet check. A Bullmastiff from a breeder in WA, by contrast, often runs to several thousand dollars with none of that vet work done yet. Where the breed gets expensive is ongoing care: a giant dog eats, is vetted and is medicated at giant-dog scale, and professional training is strongly recommended, so budget accordingly.
Are Bullmastiffs restricted in Western Australia?
No. The Bullmastiff is not a restricted breed in WA. The five restricted breeds under the Dog Act 1976 are the American Pit Bull Terrier, Dogo Argentino, Fila Brasileiro, Japanese Tosa and Perro de Presa Canario. A Bullmastiff is legal to own and to rehome normally. Like any WA dog it needs to be microchipped by 3 months of age and before it changes hands, and registered with your local council from 3 months, with a reduced fee for a desexed and microchipped dog. People sometimes assume any large guardian breed is restricted, which is not the case here. The dangerous-dog framework under the Act applies to any breed by behaviour, which is a reason to take socialisation and secure containment seriously with a powerful dog.
Is a Bullmastiff a good first dog?
For most first-time owners, no. A Bullmastiff is a large, powerful, intelligent guardian with a naturally protective streak, and it needs confident, consistent handling, extensive early socialisation and steady reward-based training. A poorly socialised, under-trained Bullmastiff is a genuine liability given its size, and that is a lot to take on cold. Most rescues will look for a home with real experience of large or guardian breeds. If this would be your first dog, be honest with the rescue and let them steer you toward a breed that fits your life.
Are Bullmastiffs good family dogs?
They can be devoted family dogs with an experienced owner and proper training. A well-raised, well-socialised Bullmastiff is calm, loyal and deeply bonded to its household, and many are gentle and patient with the children they live with. The catch is that this is a large, powerful guardian breed, so early socialisation and steady training are not optional, and supervision around visitors and small children is basic sense given the size. A foster carer who has lived with the dog can tell you how a specific Bullmastiff is with children and other animals.
How do Bullmastiffs cope with the Perth heat?
They need real care in summer. The Bullmastiff is a heavy, short-muzzled breed, which makes it more sensitive to heat than most dogs, so in a Perth summer it needs shade, constant fresh water, a cool place to rest and exercise kept to the cool of the early morning or evening. Never leave a Bullmastiff in a hot yard or a parked car, and watch for signs of heat stress. This is a genuine welfare consideration for the breed in WA, not an afterthought.
Should I adopt an adult Bullmastiff or a puppy?
For almost every adopter an assessed adult is the more responsible choice, and Bullmastiff puppies are rare in rescue anyway. With a powerful guardian breed, seeing the temperament matters: an adult has a known temperament the rescue can describe, an established size you can see rather than gamble on, often some training in place, and a lower adoption fee. A carefully matched, foster-assessed adult Bullmastiff is the sensible way into the breed.
Is it safe to buy a Bullmastiff online?
Be very careful. The online market for popular guardian purebreds is scam-prone, and Bullmastiffs are a target for fake listings and backyard breeders producing poorly socialised puppies of a breed that badly needs the opposite. A cheap puppy, a deposit request for a dog you have not met in person, or a seller who will not show you both healthy parents is a warning sign rather than a bargain. Scamwatch has documented deposit scams for puppies that do not exist. WA does not run a Pet Exchange Register or breeder source-number scheme, so the practical safeguard is the microchip: a dog sold or given away legally in WA must be microchipped and registered, so ask to see the microchip paperwork before you commit any money.
