Spreading awareness on equine muscle disease

About Us

PSSM & MFM Awareness was born in December 2019 when Christine’s horse Tex was diagnosed with PSSM1. With little help available on how to manage PSSM1 Christine turned to Facebook for help, it was in this search for answers Rebecca contacted Christine.

Once Christine found out from Rebecca how little was known about PSSM she suggested setting up the group PSSM Awareness, a group dedicated to helping UK PSSM horse owners, Rebecca agreed and PSSM & MFM awareness was born.

From there Christine began extensive research into both PSSM1 & PSSM2, she spoke to the scientists behind the PSSM tests and started producing content to help owners and professionals alike in a format that people like herself could understand, from there she established the PSSM awareness brand and helped it become the fantastic information source that it is today.

Christine Mahon and Karlo (N/P4)

Christine is a passionate and driven individual who has owned and ridden horses her whole life. As of 2020 she currently owns 2 horses an American Paint Horse named Tex, and a Gypsy Cob mare named Spice.
Christine works full time as a marketing executive for an innovative energy storage company, but in her spare time she used to enjoy competing in affiliated dressage competitions producing her horse Tex throughout the levels.
In December 2019 after a spate of poor performances Christine’s world was turned upside down when Tex was diagnosed as PSSM1 (N/P1), and in April 2020 Tex was diagnosed with additional PSSM2 (N/P3), as a result of this diagnosis and a deterioration in his condition Tex is now retired from all dressage competition and instead enjoys life as a happy hacker and driving horse. In June 2020 Christine also lost her 5 year old homebred Karlo to PSSM2 (N/P4), with Tex’s diagnosis and the loss of Karlo it has made Christine more determined than ever to spread awareness on equine hereditary muscle disease throughout the world, and to encourage more horse breeders to test equines before breeding through PSSM & MFM Awareness.

Rebecca Duke (Co-Founder)


Rebecca Duke with Finn

Rebecca is passionate about all things to do with animals especially horse welfare. She grew up on a farm and started her horse journey from a young age focusing on saving horses from neglectful backgrounds and the meat man. As of 2020 Rebecca owns 2 horses a Welsh x Hackney mare called Ditsy, and a Welsh x Irish Cob gelding called Finn.
Rebecca used to compete in show jumping and showing with Ditsy, but in 2017 Ditsy was diagnosed with PSSM1 (N/P1) after being initially misdiagnosed with laminitis, it was a fight for Rebecca to get Ditsy’s true diagnosis, and it only ever came to light through doing her own research and pushing vets for the PSSM test.
Ditsy is now retired from ridden work due to hock arthritis and enjoys a quieter life, but Rebecca still enjoys riding and concentrates on producing her young horse Finn who is proving to be very talented.
Since Ditsy’s diagnosis Rebecca set out to raise awareness on PSSM so no horse owner had to fight for a diagnosis again, she hopes to encourage more breeders to test before breeding horses, to help eliminate hereditary equine muscle disease for future generations.
