Treating a dog’s cancer in Spain costs, in 2026, between €1,500 and €6,500, depending on the type of tumour and whether it needs surgery, chemotherapy or both. Chemotherapy runs €150-400 per session and a full 3-month protocol can add up to €3,000-4,000. With Petplan España (Petplan Ibérica, S.L.) you recover 100% of the bill up to €3,100/year (€45 excess) at any vet, from €20/month.

A real case in Spain
€1,400 was the cost of chemotherapy (19 sessions) for “Argos”, a dog with lymphoma, plus €400 in diagnostic tests. As this case shows, cancer is not a one-off payment but a treatment that stretches over time.
What makes the price vary?
The type of cancer (mast cell, lymphoma, mammary tumour, osteosarcoma), whether it responds to the first drug, the number of chemo sessions, and follow-up tests. Newer treatments like electrochemotherapy, available at centres such as AniCura, sometimes need a single session.
How much does Petplan cover?
Petplan España reimburses 100% of the bill up to €3,100/year, with a single €45 excess, at any veterinary clinic. That decisively cushions a cancer treatment journey. From €20/month, for dogs, cats and rabbits. Group-wide, Petplan pays over £9 million in claims every week (Petplan UK, 2025).
