Market Overview: The Scale and Growth of Pet Food Testing

The global pet food testing market was valued at approximately USD 8 billion in 2024 and is growing at a CAGR of around 5%. This growth is driven by rising pet ownership, premiumization trends, clean-label claims, and stricter global regulations demanding routine quality checks.

Among product categories, dry food continues to dominate in sales volume due to its convenience and affordability, while wet food and treats/snacks are growing faster, propelled by premium formulations, functional benefits, and human-grade ingredients. These changing dynamics are reshaping testing priorities across the value chain.

Dry Pet Food: The Core of the Market and the Backbone of Testing

Market Share and Significance

Dry pet food — commonly known as kibble — accounts for more than 55% of global pet food sales. Its popularity lies in convenience, long shelf life, and affordability. However, its dry nature doesn’t eliminate testing needs — in fact, it increases the complexity of nutrient and contamination analysis.

Testing Focus and Challenges

Dry formulations require testing that ensures nutritional consistency, microbial safety, and shelf stability. Common tests include:

• Proximate analysis: Determines protein, fat, fiber, and ash content to verify nutritional claims.
• Mycotoxin screening: Since dry food often uses cereals and grains, it’s prone to fungal contamination (e.g., aflatoxins).
• Oxidation and rancidity tests: Monitor fat stability and shelf-life performance.
• Pathogen detection: Especially for salmonella and listeria, which can survive low-moisture environments.
• Additive verification: Ensures accurate vitamin/mineral fortification.

Consumer and Regulatory Trends

Consumers increasingly favor clean-label dry foods with minimal artificial preservatives. This trend raises demand for natural antioxidant testing and alternative preservative validation. Regulatory agencies such as the U.S. FDA and the European Food Safety Authority (EFSA) emphasize strict quality controls for dry feeds, particularly grain-based formulations, due to historical contamination recalls.

Insight

Dry food remains the testing-intensive backbone of the pet food market. With the inclusion of functional ingredients like probiotics, omega fatty acids, and superfoods, analytical complexity continues to increase, driving growth in both nutritional and stability testing services.

Wet Pet Food: Nutrient-Rich, Moisture-Heavy, and Microbially Sensitive

Market Share and Characteristics

Wet pet food represents roughly 30% of the market but commands a higher price per unit due to its palatability and nutritional density. High moisture content, however, increases microbial risk — making microbiological testing essential.

Testing Requirements

Wet pet food requires a robust testing framework, including:

• Microbiological testing: Detects spoilage organisms (yeast, mold, coliforms, Clostridium spp.) and pathogens (Salmonella, Listeria).
• pH and water activity (aₐw): Determines microbial growth potential.
• Preservative efficacy testing: Ensures shelf stability post-processing.
• Nutrient retention tests: Heat sterilization can degrade nutrients; labs test for vitamin stability post-retort.
• Packaging integrity testing: Validates can and pouch sealing to prevent contamination.

Consumer Influence

Pet owners perceive wet food as “fresh” and “closer to human-grade meals.” This perception raises the bar for traceability, ingredient authenticity, and label validation. For instance, claims like “contains real chicken” or “grain-free” must be supported by molecular or chemical assays to verify authenticity and absence of contaminants.

Insight

The wet food segment’s complexity lies not just in microbial control but also in nutrient preservation and packaging validation. Advanced analytical methods, such as LC-MS/MS for vitamin degradation and PCR-based detection for species verification, are becoming standard tools in this space.

Snacks and Treats: The Fastest-Growing and Most Diverse Category

Market Trends

Pet snacks and treats are the fastest-growing category — expanding at a CAGR exceeding 6%, fueled by emotional buying, humanization trends, and the rise of functional and training treats. With everything from dental chews to freeze-dried jerky and baked biscuits, this segment’s diversity creates highly variable testing needs.

Testing Challenges

Unlike staple pet foods, treats often have unconventional ingredients — exotic meats, dairy derivatives, or plant-based substitutes — each requiring different safety and authenticity checks.

Typical testing scope includes:

• Allergen testing: For dairy, soy, nuts, and wheat.
• Pathogen and mold testing: Especially in jerky or semi-moist treats susceptible to microbial growth.
• Moisture content analysis: Ensures regulatory compliance and prevents spoilage.
• Additive verification: Checks for artificial colorants, preservatives, and sweeteners (e.g., xylitol).
• Label accuracy testing: Confirms that “natural,” “organic,” or “grain-free” claims are valid.

Regulatory Context

Agencies such as the FDA (U.S.), CFIA (Canada), and FSSAI (India) have begun increasing scrutiny on imported and specialty treats, particularly after previous contamination recalls. Retailers now often require independent third-party testing before stocking private-label treats.

Insight

The treats segment is innovation-driven and consumer-facing — meaning that testing not only ensures safety but also enables marketing claims. As “functional treats” with added probiotics, collagen, or CBD extracts rise, regulatory testing for additive safety and dosage verification will intensify.

Functional and Specialized Foods: Bridging Nutrition and Therapeutics

Emerging Subcategory

Beyond traditional dry, wet, and treat formats, there is a surge in functional or veterinary pet foods — products targeting specific health outcomes such as weight management, gut health, or skin and coat support.

Testing Requirements

Testing in this segment goes beyond conventional safety parameters and includes bioactive compound validation:

• Probiotic viability counts (CFU/g)
• Omega-3 and fatty acid profiling
• Antioxidant activity (ORAC testing)
• Additive stability under storage and temperature variations

Regulatory and Market Drivers

As these products approach the nutraceutical boundary, authorities require evidence for efficacy and safety similar to that for animal feed supplements. This has created opportunities for testing labs to provide method development, stability studies, and regulatory dossier support.

Insight

Functional pet foods represent the testing frontier — blending the rigor of food safety with the precision of pharmaceutical testing. This crossover is a key growth driver for specialized analytical labs.
