Hi Flossie –
4Health is a Tractor Supply owned brand but they outsource the manufacturing. The grain-inclusive dry food is manufactured by Diamond, the grain-free dry food is manufactured by Ainsworth and the canned food is manufactured by Simmons. Don’t even bother trying to contact Tractor Supply’s customer service with questions about 4Health – they’re useless. For the salmon and potato dry food I’d contact Diamond directly. I’ve contacted Diamond in the past with questions about specific nutrient values in various 4Health formulas and they’ve always been very helpful and quick to respond.
