PetSmart: How One Chain Conquered America's Pet Retail and What It Means for Pet Owners

PetSmart operates 1,500 stores across North America, controlling approximately 25-30% of the pet specialty retail market—making it the single largest pet retailer in the United States. But the real story isn't about store count. It's about how PetSmart became the distribution chokepoint for a $136 billion global pet industry, how consolidation reshaped pet supply economics, and what happens when a single retailer controls access to pet care products that millions of owners depend on daily.

The American pet economy has exploded. Americans now spend more on pets than on books, toys, or sporting goods combined. Pet ownership climbed from 67% of U.S. households in 2019 to 72% by 2023, representing approximately 90 million pet-owning homes. Yet this massive market is controlled by a surprisingly small number of retailers. PetSmart's consolidation strategy reveals how retail power increasingly concentrates in fewer hands—and what that concentration costs consumers.

The Consolidation Playbook: How PetSmart Became Unavoidable

PetSmart's dominance wasn't built on innovation. It was built on acquisition and scale. The company was founded in 1987 but didn't become a true giant until the late 1990s, when it aggressively acquired regional pet supply chains. By 2000, PetSmart had absorbed Petco's primary competitor position, creating a two-company duopoly in pet specialty retail.

The 2015 acquisition of PetSmart by private equity firm BC Partners for $8.7 billion marked a turning point. Under PE ownership, the strategy shifted: expand grooming services, consolidate suppliers, raise prices, and reduce competition. By 2023, when PetSmart went public again, the company had refined a playbook that other retailers follow:

Consolidation metrics:

• 1,500+ stores across North America (vs. Petco's 1,400)
• 25-30% market share in pet specialty retail
• $8+ billion in annual revenue
• 59,000+ employees (many part-time, low-wage positions)
• Grooming services in 80%+ of locations

The company's strategy mirrors Walmart's 1990s playbook: achieve scale, negotiate supplier terms that no competitor can match, then use that leverage to raise prices on consumers while squeezing supplier margins. PetSmart vendors report that the company demands exclusive distribution deals, price concessions, and marketing contributions that only large suppliers can afford.

The Hidden Economics: Why Pet Prices Keep Rising

Here's the economic paradox: PetSmart has achieved unprecedented market concentration in pet retail, yet pet supply prices have risen 20-30% in the last five years—far faster than general inflation. This seems backwards. Consolidation should theoretically create efficiency and lower prices. Instead, it's created pricing power.

The mechanism is simple: when a retailer controls 30% of a market and has limited competitors (only Petco, plus fragmented independent shops and online retailers), it can raise prices without losing significant volume. Pet owners have few alternatives—they need supplies for their animals, and PetSmart's scale gives it convenience and breadth that independent shops can't match.

Pet supply pricing reality (2019-2024):

• Premium pet food: +25% price increase
• Flea and tick treatments: +18% increase
• Litter and bedding: +22% increase
• Pet medications: +35% increase
• Overall pet care spending: +31% annually

This pricing power extends through grooming services (where PetSmart controls significant regional capacity) and through exclusive product lines that the company develops with suppliers. A dog owner looking for a specific food or medication often finds it's only available at PetSmart or through online retailers—which creates an implicit pricing floor that PetSmart can match or exceed.

Supply Chain Consolidation: The Supplier Squeeze

The pet supply industry is fragmented on the vendor side but concentrated on the retail side. This creates enormous pressure on suppliers. Pet food manufacturers, pharmaceutical companies, and accessories makers all depend on PetSmart for distribution to reach 90 million pet-owning households. That dependency creates leverage.

PetSmart uses this leverage aggressively:

• Exclusive deals: Vendors are pressured to offer products exclusively to PetSmart for 6-12 months, locking out competitors
• Slotting fees: New products must pay PetSmart to secure shelf space (ranging from $5,000-$50,000 per product)
• Markdown agreements: PetSmart demands suppliers fund markdowns when products don't sell
• Marketing co-op: Vendors must contribute 3-5% of wholesale revenue to PetSmart's advertising

These terms are standard in retail, but their impact on pet industry competition is significant. Small and medium suppliers—artisanal pet food brands, independent supplement makers, regional pet medication companies—often can't afford PetSmart's terms. This creates a moat protecting established brands while making it nearly impossible for new competitors to enter.

The result: shelf space at PetSmart has become the bottleneck for any pet product company wanting to reach scale. This gives PetSmart control not just over distribution but over which innovations actually make it to consumers.

Labor Economics: The Grooming Crisis and Low-Wage Retail

PetSmart's expansion into grooming services has been highly profitable for the company but created a hidden labor crisis. The company employs thousands of pet groomers, many part-time or gig-classified, with minimal benefits and significant injury risk.

Pet grooming is physically demanding work—repetitive motions, animal bites and scratches, chemical exposure to shampoos and treatments, and long hours standing. Yet groomer wages at PetSmart average $15-18/hour, with limited benefits, high turnover (60%+ annually), and frequent wage disputes.

The company has faced multiple lawsuits regarding:

• Wage theft and unpaid overtime
• Misclassification of employees as independent contractors
• Unsafe working conditions (animal-related injuries without proper reporting)
• Retaliation against workers attempting to organize

PetSmart handles millions of grooming appointments annually, generating significant revenue from grooming services, yet the workers performing the service are among the lowest-paid employees. This reflects a broader retail pattern: scale consolidation benefits corporate owners and shareholders, while labor bears the cost.

The Online Competitor Question: Why Amazon Hasn't Dominated Pet Retail

PetSmart's consolidated position has survived the Amazon era better than most traditional retailers. Why? Pet supplies are lower-margin, high-volume products where shipping costs matter significantly. Heavy items (pet food, litter) are expensive to ship, giving PetSmart's physical stores an advantage. Additionally, PetSmart's grooming and veterinary services—now offered in many locations—create sticky, in-person value that online retailers can't replicate.

Chewy.com, an online pet supply retailer, has captured significant market share (approximately 15-20% of the online pet market). But Chewy's success has actually reinforced PetSmart's position: Chewy was acquired by PetSmart's parent company (BC Partners and later public shareholders) in 2017 for $3.35 billion, then spun off. Now, PetSmart owns Chewy as a separate brand, meaning it controls both physical and online distribution. Whether a pet owner shops in-store or online, PetSmart captures the transaction.

Regional Economic Impact: The Store Closure Problem

PetSmart's consolidation strategy includes aggressive store rationalization. When the company identifies unprofitable locations or overlapping markets, it closes stores—sometimes dozens at once. This creates economic disruption in smaller markets where PetSmart was the only pet specialty retailer.

For rural areas and smaller cities, a PetSmart closure often means:

• No local pet specialty retail option (forcing online shopping or longer trips)
• Loss of grooming services locally
• Reduced access to prescription pet medications
• Loss of 30-50 jobs per location

This dynamic mirrors what happened in grocery retail: consolidators like Walmart and Amazon created "retail deserts" in unprofitable areas while maintaining dense coverage in affluent suburbs. Pet retail is following the same pattern.

So What? What This Means for Different Audiences

For Pet Owners:PetSmart's consolidation has created convenience and wide selection, but at the cost of higher prices and reduced alternatives. Pet owners with resources can shop around (Chewy online, Costco, local independent shops). Pet owners without resources—those in rural areas, without reliable internet, or with limited transportation—increasingly depend on PetSmart's pricing and availability, giving the company pricing power over their pet care decisions.

For Pet Industry Vendors:PetSmart's consolidation has made it an essential distribution channel but a difficult partner. Innovation and small-company competitiveness are constrained by the leverage PetSmart wields through slotting fees and exclusive deals. The most successful pet product companies are either large enough to negotiate independently or willing to accept PetSmart's terms.

For Policymakers:PetSmart's dominance raises questions about retail consolidation that antitrust regulators haven't adequately addressed. While the FTC has focused on grocery consolidation and tech platform monopolies, pet retail consolidation has escaped scrutiny—despite creating similar market concentration problems.

For Workers: Pet retail and grooming jobs at PetSmart offer accessible employment but come with low wages, limited benefits, and high injury risk. The company's scale has not translated into improved labor standards; if anything, consolidation has enabled wage suppression while maintaining high productivity expectations.

PetSmart's story is the story of modern retail consolidation: a single player achieves scale, uses that scale to control suppliers and competitors, raises prices on consumers, suppresses wages for workers, and captures value for shareholders and private equity owners. The fact that it operates in pet retail—an industry Americans care deeply about emotionally—obscures the economic dynamics reshaping American consumer markets broadly. Understanding PetSmart helps explain why consolidation keeps happening across retail sectors and why breaking up market concentration has become a defining policy challenge.
