Companion animal oncology is emerging as one of the highest-growth sub-segments in veterinary medicine. Cancer is now the leading cause of death in dogs over the age of 10, with approximately 6 million new canine cancer diagnoses annually in the U.S. alone. IDEXX launched IDEXX Cancer Dx in 2025 for canine lymphoma — a simple blood test screening — and plans to expand the panel to canine mast cell tumors. PetDx's OncoK9 liquid biopsy detects 30+ cancer types from a single blood draw. Therapeutic innovation includes Stelfonta (tigilanol tiglate) for mast cell tumors, Tanovea (rabacfosadine) for canine lymphoma, and emerging mAb pipelines from Zoetis, Elanco-Kindred, and Aratana. The companion animal oncology market is forecast to grow at high-double-digit rates through 2030.
This report provides significant competitor information, analysis, and insight critical to the development and implementation of effective marketing and R&D programs.
