Driven by pet humanization, aging pet populations, and premiumization of pet food, the market is evolving fast. Brands that once sold treats now sell wellness. Retailers that once focused on price now compete on personalization, trust, and science.

The 2025 Buyer Playbook: What Really Drives Purchase Decisions
Pet supplement buyers in 2025 whether pet parents, veterinarians, or specialty retailers make decisions based on trust, transparency, and tangible benefits.
Here’s what truly drives deals today:
