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!

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.
PUREHEARTBUL Giselle

Pureheartbul Giselle (AI)

Giselle - Born 8th March 2025

Giselle is my home bred stunning fawn girl from Dukory Silver Blue (Boo)

Boo came out of retirement to have this litter due to Ava’s inability to have another litter. Boo, you are a champion in my eyes and one of a kind dam that can never be replaced.

The name Giselle originates from the French language and is derived from the word gisil, which means pledge or promise. The name carries with it the connotation for commitment and loyalty.

She is a confident bubbly girl who has been brought up with Cora and Argos’s brindle boys. They being bigger than her, she has steadfastly stood her ground and doesn’t put up with anything they dish out. I just love how easily she adapts.

This little girl has already grabbed my heart and I’m absolutely guttered as at 14 weeks old this girl is now officially retired. Unfortunately she has been diagnosed with a birth defeat call pigeon breast. This is a congenital condition. Pigeon breast in dogs, also known as pectus carinatum, refers to a chest deformity where the breastbone (sternum) protrudes outwards, causing a pointed or “pigeon-like” appearance. It’s a genetic condition, often present at birth, but may not be noticeable until the dog shows symptoms like breathing difficulties or failure to thrive. While it can be hereditary, it’s generally not a cause for major concern unless it compresses the lungs or heart.

Unfortunately for Giselle it is affecting her heart and I am just monitoring it at the present moment and in discussions with my veterinarian team on when and/or if she is a good candidate for an operation to correct this condition.

More information to come over the coming weeks.
