The growing number of pet owners is expected to drive the expansion of the companion animal diagnostics market in the coming years. Pet owners are individuals who take responsibility for the care, well-being, and management of their pets. Pet ownership has increased due to greater awareness of the emotional and health benefits of pets, as well as the availability of pet-related services and products. Companion animal diagnostics support pet owners by providing critical health information and enabling early detection of diseases, ensuring timely and effective care. For example, in March 2025, the American Pet Products Association (APPA), a US-based nonprofit trade association, reported that approximately 94 million US households owned at least one pet in 2024, up from 82 million in 2023. In 2024, about 18.8 million (20%) of pet-owning households were headed by Generation Z, representing a 43.5% increase in their share compared to 2023. Therefore, the rise in pet ownership is fueling growth in the companion animal diagnostics market.

Key companies in the companion animal diagnostics market are investing in reference laboratories to enhance remote diagnostic capabilities and improve access to specialized veterinary care.
