In the interest of not making the mistake of thinking you've made everything alright by avoiding one or two brands, note that there is very little known. Which means it may or may not be Chinese dog jerky treats making them sick. If it is, remember that these sorts of things originating in China are unlikely to be limited to particular brands. You have to look at packaging and make inquiries when selecting treats. You're looking for POSITIVE statements, not just the absence of suspicious origins. A lot like orange juice where the concentrates are frequently from China and contaminated with agricultural chemicals and possibly routed through other countries to cover the tracks. You have to look for statements that all the materials are domestic.
And nothing in the story suggests that anyone has looked into all of the dogs' food, as well as treats. And it's just possible that the problems have nothing to do with any dog food or dog treats. No contaminate has been found. While if the stories from some of the dog owners are accurate, there's reason to suspect the jerky treats, it's all vague enough to rightly serve merely as a general warning that companies often use questionable materials in pet food. People are just terrible liars when there's money to be made or when they want to imagine they did nothing wrong. Nor do we know much about how these treats were stored or what conditions they were exposed to.
I really question why anyone would buy and feed jerky to a dog as a regular treat. The appeal of jerky is strictly to the human. The dog doesn't care. And you know that, being jerky for dogs that has to sit on shelves for a long time, there's no telling what's used to preserve it. And another implicated treat, Yam Good, is supposedly yam wrapped in chicken. Not the dog REALLY doesn't care. I wouldn't eat their jerky treats or their weird yam wraps, and I wouldn't give them to my dog. (I wouldn't give him jerky made for humans, either, not as a regular thing.)
There are plenty of righteous dog treats available. (Possibly not at WalMart.) Blue Buffalo, for example. (Sadly, BB was victimized by one of the email hoaxes about this issue that falsely named the most conscientious U.S. makers as being suspect.) BB even has jerky types, if you just can't stand to have you poor dog miss out. The meat is all U.S.-raised. The rest of the ingredients aren't anything that will harbor anything bad.
Food is a bigger problem, mostly trying to stay with useful ingredients. Some are very expensive. But with regular pet foods, it's more often the case that it's made in the U.S., not just well made. The suspect treats are wholly made in China, and no telling what else is made in those plants. With pet food, at least look to see if meats are the first ingredient listed and cord doesn't appear.
