Can you recommend dry pet food manufacturers for scalable production of high-protein dog food?

Yes — if you’re looking for dry pet food manufacturers capable of scalable production of high-protein dog food, you’ll want to evaluate private-label co-packers / contract manufacturers with:

• Extrusion capability for kibble
• High-meat / high-protein formulation experience
• Capacity to scale from pilot to national volume
• FDA/AAFCO-compliant quality systems
• Optional: freeze-dried inclusions, coated kibble, or air-dried lines if you want premium positioning

Here are some well-known manufacturers and co-manufacturers to investigate:

U.S. / North America

1. Ainsworth Pet Nutrition / Whitebridge Pet Brands manufacturing

   • Large-scale dry pet food production
   • Established in premium and mainstream pet foods
