The global companion animal genetics market was valued at USD 855.4 million in 2025 and is expected to reach USD 1,650.5 million by 2033, expanding at a CAGR of 8.7% from 2026 to 2033. The market is forecast to increase from USD 917.5 million in 2026. North America led the global market in 2025, capturing a 30.9% revenue share.

Growth in companion animal genetics is being supported by several structural trends, including increasing pet humanization, greater emphasis on preventive veterinary care, wider adoption of direct-to-consumer (DTC) genetic testing, and growing concerns about hereditary and breed-specific diseases.

Key Market Trends & Insights

Dogs remain the leading animal segment. Dogs accounted for the largest share of the companion animal genetics market, representing 49.3% of the market in 2025. The strong position of this segment reflects widespread genetic testing among dog owners and breeders seeking information on breed composition, hereditary conditions, and potential health risks.

Genetic disease testing leads by type. The genetic disease testing segment held the largest share at 56.3% in 2025. Increasing awareness of inherited diseases and the need for early identification of genetic risks are supporting demand for these testing services.

Private distribution channels dominate. The private segment represented 76.6% of the market in 2025, making it the leading distribution channel. This reflects the important role of private veterinary providers and related services in delivering genetic testing and companion animal healthcare solutions.

Regional Market Landscape

North America was the largest regional market in 2025, accounting for 30.9% of global revenue. The U.S. held the largest country-level share during the year, supported by established veterinary infrastructure and growing consumer awareness of genetic testing for pets.

Meanwhile, Asia Pacific is projected to register the fastest CAGR from 2026 to 2033. Increasing awareness of companion animal health, changing attitudes toward pet ownership, and expanding access to veterinary and genetic services are contributing to the region's growth momentum.

Hereditary Diseases Strengthen Demand for Genetic Testing

The increasing prevalence and recognition of hereditary and breed-specific conditions among dogs and cats represent a major growth factor for the companion animal genetics market. Numerous popular purebred animals have genetic predispositions to conditions including hip dysplasia, cardiomyopathies, and inherited cancers.

The Online Mendelian Inheritance in Animals (OMIA) database documented 784 single-locus diseases or traits in dogs and 361 in cats that had been genetically explained as of December 2020. This growing body of genetic knowledge provides an important foundation for identifying inherited risks and supporting more informed animal health management.

Pet owners and breeders are increasingly turning to genetic testing to identify carriers and reduce the likelihood of transmitting defective genes to future generations. Beyond supporting breeding decisions, genetic information can help guide long-term healthcare planning. Early identification of genetic risks may improve animal welfare while potentially reducing veterinary expenses associated with managing chronic inherited conditions.

Direct-to-Consumer Testing Expands Market Access

The expansion of direct-to-consumer genetic testing kits has made companion animal genetics more accessible to pet owners. Companies such as Embark and Wisdom Panel provide at-home testing kits that can generate information on breed composition, ancestry, and health risks without requiring a veterinary visit.

Growing e-commerce penetration and digital marketing have further increased consumer awareness of these services. In addition, subscription-based offerings and integrated wellness recommendations are creating additional opportunities for ongoing customer engagement.

By making genetic information available directly to consumers and connecting test results with preventive healthcare decisions, the DTC model is broadening the addressable market. This accessibility is expected to remain an important contributor to the continued expansion of the companion animal genetics industry.

Pet Humanization Drives Personalized Animal Healthcare

The increasing tendency to treat companion animals as family members is changing spending patterns across veterinary healthcare. Pet owners are placing greater emphasis on personalized healthcare, disease prevention, nutrition, and long-term wellness.

Genetic testing can help pet owners identify hereditary conditions, understand potential disease risks, and make more informed decisions regarding nutrition, breeding, and lifestyle management. Growing awareness of breed-specific disorders in dogs and cats is also encouraging earlier adoption of genetic solutions.

At the same time, higher expenditure on veterinary services is supporting demand for technologies that can provide actionable information about an animal's health. The combination of pet humanization, preventive care, and greater awareness of genetic disease therefore represents a significant growth opportunity for the industry.

Biobanks Support the Development of Precision Pet Healthcare

Biobanks are emerging as an important resource for advancing companion animal genetics. Initiatives such as the Mars Petcare Biobank create longitudinal resources containing genomic, clinical, and lifestyle information.

Connecting genomic data with health outcomes can support earlier disease detection, personalized care, and preventive strategies. These datasets also provide researchers and the veterinary sector with opportunities to identify new genetic markers and improve understanding of disease mechanisms.

As genomic information becomes increasingly integrated with clinical and lifestyle data, biobanks could contribute to the development of more precise approaches to companion animal healthcare and accelerate innovation across the broader genetics ecosystem.

Companion Animal Genetics Market Size & Forecast

The market is expected to maintain steady expansion throughout the forecast period:

• 2025: USD 855.4 million
• 2026: USD 917.5 million
• 2033: USD 1,650.5 million
• CAGR, 2026–2033: 8.7%

Overall, the companion animal genetics market is being shaped by the convergence of genetic disease awareness, preventive healthcare, pet humanization, DTC testing, and advances in genomic research. These factors are expanding the role of genetic information from breeding decisions toward broader personalized and preventive pet healthcare.
