Our Commitment
At OncoTails, our commitment is to ensure pets with cancer receive expert, personalised, compassionate care without unnecessary stress or disruption.
Who We Are & How We Work
OncoTails is led by Dr Sarah Mason FRCVS, a double board certified Specialist in Medical and Radiation Oncology and Fellow of the Royal College of Veterinary Surgeons —
a mark of outstanding expertise and contribution to the profession.
​
We work in partnership with:
• Independent veterinary practices & Referral hospitals
• Veterinary surgeons and nursing teams
• Pet families who value continuity and calm
​
Our model is collaborative, clinically robust and practice-centred.
We provide specialist guidance, treatment planning and case support - allowing oncology care to remain within the primary practice wherever appropriate.
Our Approach to Oncology Care
