I really like Solid Gold products.
That said, Solid Gold gets a bit of a bad rap sometimes because they still use Diamond as a co-packer for some of their varieties. Last I knew, was that Diamond manufactures Hund ‘n Flocken, WolfCub, WolfKing and Just a Wee Bit at their Meta, MO plant. Crosswind Industries, located in Kansas, manufactures Holistique Blendz, Hundchen Flocken, Barking at the Moon, MMillennia and Sun Dancer.
I used Barking at the Moon for one of my dog’s once, she ate it with no problems. Maybe just try a small bag to start.
