*Wow! Pure Heart Bullmastiffs. Perfect name for what they deliver. Our 7-month-old Elvie is perfect for us. Her personality is fantastic - soft and gentle; protective and caring; crazy and fun. She makes us laugh, sigh, and be so very grateful to have her in our lives. Oh yes, Pure Heart Bullmastifss have been awesome to deal with!

We have been so excited to welcome Mollie into our home and shower her with love. She is the most wonderful, affectionate dog and I know this all comes down to her breeding and the amazing love and care Karen and Graeme give to raising their puppies. Every step of this process has been made easier by Karen who goes above and beyond - you can see her passion for good, ethical breeding shining through. We felt well informed and well supported throughout the process of waiting for a puppy and then bringing Mollie home. We are so grateful we found Pureheartbul!

Karen and Graeme are genuinely the nicest people, they are open, honest, passionate, knowledgeable; an absolute pleasure to deal with. They breed amazing quality dogs and they do it with love.

Nearly one year ago, Maggie was born. The 2 months long wait was filled with anticipation and many questions, to which Karen was very attentive and patient with. Wait over, it's been nothing but joy. Maggie has the best temperament and loves everyone. Cat and chooks included. I can't recommend Pureheart enough. I wish you all the best, many more puppies and the energy required to deal with them. :) Thank you!

I recently picked up my beautiful bullmastiff puppy from Karen at Pure Heart Bullmastiffs, and I couldn’t be happier! From the very beginning, Karen was kind, welcoming and incredibly knowledgeable about the breed and their health. Her love and dedication to all her dogs is so evident. Their welfare and wellbeing are clearly her top priority. My puppy Banjo is so calm and well-adjusted, and he has slotted into my lifestyle with ease. This is a true testament to the loving and structured environment he came from. With their gentle demeanour, loyalty and big loving hearts, bullmastiffs are really the best dogs you could ask for. I would absolutely recommend Pure Heart Bullmastiffs to anyone looking for a responsible, ethical breeder who genuinely cares about her dogs!

He has been exactly what our family needed, with his beautiful nature and all of the love he has. Karen has been very supportive at every step and has great advice, she goes above and beyond and her love for the fur babies shines through in their temperament and nature.

Useful information that worth sharing.

Update 14th January 2026

Well my PUREHEARTBUL Cora The Explora has well and truly recovered from her first big litter and she’s so attentitive to looking after Giselle and Amor. As I’m wanting to continue DUKORY Silver Blue (Boo’s) lines I have found a lovely stud dog from the DUKORY lines that I’m very excited about putting him over Cora when she comes into season around March/April/May 2026.

Mason’s owner and I are expecting beautiful fawn babies from this litter with big heads, lovely shaped ears,  stocky builds, correct temperament and lovely lines going back to Graecia Kennels and Cruft winners. This image shows the similarities between Mason and my very placid and retired matriarch girl Dukory Silver Blue (Boo) who is now 6 years old. 

Update 13th September 2025

After a massive litter in March, Cora is having a well deserved break from breeding for at least one, maybe two seasons. As a big girl having big litters I need to ensure she is is top condition for her next litter. She is the best mumma I’ve breed and ensuring her safety is my top priority. I am waying up the possibility of breeding her again with Argos or breeding her with semen from another sire.

Amor my new red girl is now 6 months and I will be breeding her with my red boy Angus after she has reached her legal requirements of breeding age of 18 months which will be around this time 2026. Exciting times ahead and can’t wait to see what this duo will produce.

Update 5th February 2025

With the passing of PUREHEARTBUL Cotton Candy and the retirement of PUREHEARTBUL Dainty Lady Ava, I have decided to do one last mating of DUKORY Silver Blue (Boo) via surgical insemenation with frozen semen from GAMEGUARD Stormin Norman. If successful the expected whelping date is Wednesday 19th March 2025. I will be keeping a bitch from this litter for future breeding with my boy BULLRYLL Son OZebulon (Angus).

The successful mating of PUREHEARTUL Wiggle It Argos and PUREHEARTBUL Cora the Explora with a whelping date of 10th March 2025 means the puppies are available from 6th April 2025.

This is going to be a very busy time for me at Pure Heart Manor.

Update 31st July 2024

I am very excited to announce that the mating between PUREHEARTBUL Danity Lady (Ava) and BULLALRYLL Son OZebulon (Angus) produced eleven beautiful red and fawn babies. Puppies were born under a c-section due to one puppy who just happened to be the largest of this litter and feet first was stuck in the birth canal. Eight boys and three girls were born 16th July 2024. Sadly I lost a boy three days later.

All puppies are growing beyond expectation and at two weeks most are close to or over a kilo plus already. I’m looking forward to watching them grow over the coming weeks and still have some males available.

Contact me if your interested in a puppy on 0414 680 157 and they will be ready for their forever homes on 10th September 2024.

Update 19th September 2023

I am very excited to announce that Boo’s pregnacy is confirmed and puppies due date is 16th October 2023…

Update 17th August 2023

Our next breeding is now underway with Angus and Boo. Boo has been cleared for breeding by our veterinarian. This pair are getting some special one-on-one time with each other and Angus is a boy in love. He is so smitten with her that he won’t leave her side although she’s still the boss.

As a natural mating was not successful we arranged two natural AI’s with our veterinarian and if successful Boo’s due date will be 16th October 2023. This means that puppies will be available around 11th December 2023.

As always updates will be advertised on my Facebook page.

Update 27th June 2023
Here at Pure Heart Bullmastiff’s, our breeding plan is always about the needs of our dogs and to follow the DogsNSW Regulations. Puppies will be available following these guidelines thus ensuring our bitches are safe.

We look for special homes for our fur babies and we are looking for owners who can give our puppies a loving home with a safe environment.
 

With our litter from Angus and Bonnie done I have decide to retire Bonnie and will be looking to re-home her when she has recovered from her speying in the next few weeks and once cleared by out Veterinarian. If you are interested in taking on an almost 4 year old adult female then please give me a call on 0414 680 157.

We are now preparing for our next mating with Angus and Boo. Boo is scheduled to come into season around August to September 2023. As this is not an exact science, dates of course may change.

I have decided to remove the waiting list from my application process as I now believe that when someone are ready for a puppy they will be in contact. Of course, I am always available to for a chat to discuss purchasing a puppy or any questions you may have.

“Happiness is a warm puppy.”
