Companion Animal Diagnostics Market Size & Share 2025 - 2034

Companion Animal Diagnostics Market Size

The global companion animal diagnostics market was valued at USD 2.4 billion in 2024. The market is anticipated to grow from USD 2.6 billion in 2025 to USD 5.8 billion in 2034, growing at a CAGR of 9.3% from 2025 to 2034. The market is experiencing considerable growth driven by increasing pet population globally, high adoption of pet animals for companionship, rising cases of infectious and chronic diseases in animals, and rising expenditure on veterinary care.

As per a recent study published by GlobalPET, there are over one billion animals kept as pets worldwide. The number of households with pets in the U.S., Brazil, Europe, and China alone has exceeded half a billion. Also, more than half of the world's families are said to have at least one pet. Such a high volume of pets increases the demand for various pet care products, thereby boosting market growth.

The rising trend of pet humanization and increased consumer spending on pet care products and veterinary services are major growth drivers. As owners increasingly consider pets as a part of their family, the average amount spent per household on pets is rising. For example, an average American pet owner spent USD 1,960 on their pet(s) in 2023. The average pet dog costs USD 143 per month in 2024, whereas cat ownership costs USD 90.5 per month per cat. As households increase their spending on pets, there is a higher demand for various pet care services, such as companion animal diagnostics, thereby fueling market growth.
 

Moreover, the increasing occurrence of zoonotic diseases as well as the possibility of infectious outbreaks in companion animals have been propelling the companion animal diagnostics market. There are policies pertaining to the health of animals due to concerns regarding their health and the spread of diseases. These policies have led to the implementation of several programs aimed at ensuring disease control. Regulatory authorities across the world are imposing strict policies to prevent the outbreak of animal borne diseases and propelling the use of animal diagnostic solutions, thus contributing to market growth. Further, several technological advancements in the field of veterinary medicine are set to positively influence the animal healthcare industry.
 

Companion animal diagnostics refer to the process of identifying, detecting, and monitoring diseases or health conditions in pets through various diagnostic tests. These tests may include blood and urine analysis, molecular diagnostic methods, serological assays, and other specialized examinations.
 

Companion Animal Diagnostics Market Trends

• High occurrence of zoonotic and other infectious diseases in animals is a major factor fueling the market. Increased prevalence of diseases such as canine distemper, parvovirus, rabies, kennel cough in dogs, and feline leukemia, feline immunodeficiency virus (FIV), and Feline infectious peritonitis (FIP) in cats severely endangers their health.
   
• For example, as per the Cornell University College of Veterinary Medicine, Feline leukemia virus (FeLV) is one of the most common and important infectious diseases in cats, affecting between 2-3% of all cats in the U.S. and Canada. Similarly, studies report that each year, about 400 to 500 cases of rabies are reported in domestic pets. As per the CDC, every year, rabies kills 70,000 people worldwide. Dogs cause 99% of human rabies deaths outside the U.S.
   
• Such a rising risk of zoonotic and infectious diseases has shifted focus toward preventive approaches, including extensive use of diagnostic solutions, which is set to positively drive the market growth.
   
• Also, the availability of advanced medical facilities for pets, cutting-edge medical devices, drugs, and pet insurance is further set to positively impact industry growth.
   
• The rising prevalence of several chronic diseases in animals, such as obesity, diabetes, and cancer, increases the demand for diagnostics and therapeutic modalities, further enhancing market growth. For instance, the Veterinary Cancer Society estimates that one in four dogs will be diagnosed with cancer in their lifetime, and that cancer is the leading cause of death in pets that are beyond middle age.
   
• Further, several initiatives by government and non-government bodies towards better animal welfare and safety propel market growth. For example, the U.S. Food and Drug Administration (FDA) has developed networks such as the Veterinary Laboratory Investigation and Response Network (Vet-LIRN). These networks connect veterinary laboratories across the country to monitor and investigate disease outbreaks. They provide crucial support for rapid disease detection and promote standardized diagnostic practices. As a result, the infrastructure needed to support animal health is improving, creating a foundation for increased adoption of diagnostics technologies.
   

Companion Animal Diagnostics Market Analysis

The market was valued at 2 billion in 2021. The market size reached USD 2.1 billion in 2022 and USD 2.3 billion in 2023.
 

Based on the product, the market is segmented into consumables and instruments. The consumables segment accounted for the highest market share and was valued at USD 2 billion in 2024.
 

• Unlike instruments, consumables such as kits, reagents, assays, blood collection tubes, slides, and other diagnostic supplies are used in every diagnostic test, leading to continuous replenishment needs. Hence, as the veterinary testing volume rises, so does the demand for these consumables. This ensures steady revenue and growth in the consumables segment.
   
• Also, with the growing trend of pet humanization, more owners are opting for preventive healthcare, which further drives up the usage of consumables in regular check-ups and early disease detection.
   
• Advancements in diagnostic technologies have led to the development of more specialized and accurate tests, many of which rely heavily on high-quality consumables. For instance, point-of-care testing, which allows rapid on-site diagnosis, relies on pre-packaged kits designed for single use, contributing significantly to market volume.
   
• Thus, as veterinary clinics and hospitals increasingly adopt these technologies, the demand for associated consumables is anticipated to rise, thereby driving the market growth.
   

Based on technology, the companion animal diagnostics market is segmented into clinical biochemistry, immunodiagnostics, molecular diagnostics, hematology, urinalysis, and other technologies. The clinical biochemistry segment dominated the market in 2024 and is anticipated to grow at a CAGR of 9.4% over the analysis timeframe.
 

• Clinical biochemistry tests are often performed in veterinary practice for the general welfare and organ function of companion animals. By testing blood and other body fluids, clinical biochemistry enables veterinarians to identify diseases such as diabetes, liver disease, kidney abnormalities, and electrolyte imbalance.
   
• These tests are conducted on a regular basis during wellness exams, pre-surgical exams, and in animals that show signs of illness. The wide usage of clinical biochemistry in a vast array of conditions makes it a central diagnostic methodology, propelling its strong demand in veterinary clinics.
   
• Increasing availability of advanced diagnostic equipment capable of delivering quick and accurate biochemical results further increases the adoption of these tests.
   
• Furthermore, increased awareness among pet owners regarding the advantages of early detection and continuous monitoring of health has driven demand for clinical biochemistry testing, thereby solidifying the segment's position in the overall market.
   

Based on the application, the companion animal diagnostics market is segmented into bacteriology, pathology, parasitology, and other applications. The bacteriology segment dominated in 2024 and is anticipated to reach USD 2.4 billion by end of 2034.
 

• The bacteriology segment holds a leading market share in the market by virtue of its essential function to detect bacterial infections that are typical of pet animals.
   
• Skin infections, urinary tract infections, respiratory infections, and gastrointestinal upsets often need to be diagnosed using bacterial culture and sensitivity testing in order to be diagnosed and treated correctly.
   
• In addition, developments in bacteriology like simplified culture procedures, quick antigen tests, and coupling with molecular technology have significantly enhanced the speed, precision, and value of these tests.
   
• These technological advances, coupled with increasing investment in animal health infrastructure, most notably reference labs and point-of-care facilities, have solidified bacteriology segment as a dominant position in the market.
