美国采购需求：狗粮工厂、狗粮生产商、狗粮批发商、狗粮、食品、批发狗粮

I'm interested in sourcing natural cow ears for dogs. I'm looking for high-quality options that are safe and appealing to dogs. It would be great to know more about your product specifications, including size variations, packaging options, and any certifications or testing that ensures the products meet safety standards. Additionally, I'd like to get some information about your pricing structure, minimum order quantities, and lead times for delivery. If you have any available samples, that would be helpful for us to evaluate. Please let me know the details at your earliest convenience, as we're eager to establish a potential partnership with a reliable supplier.
