One of my crew guy's dog got some of that poison sh!t, but recovered! Anyway, it appears to be primo brands like Iams and Science Diet as well as store brands like Walmart's OL Roy brand that are the problem! Purina and Frikies appear to be safe. It's all the smaller brands but it all adds up to being one hell of bad situation. Purina Chow and Friskies probably rely on themselves of other suppliers. This poison came out of china.
