Bests & Worsts Reviews from Amazon

I've been feeding my dog TOTW for over a year now. I have purchased through Amazon and locally. Recent local purchase looked different to me. max was reluctant to eat it...he's a lab who loves his food so I was a little concerned but didn't think much of it. Well, I should've listened to my eyes and his reluctance. Within a few days of barely eating the new bag of food he had severe diahrrea with substantial amount of blood in it. Vet couldn't find a physical cause. He was weak which was a result of the blood loss. He was anemic. Meds to stop the intestinal bleeding, probiotics, and a special diet later and he's better. (Don't forget thevhefty vet bill) I've seen lots of similar posts lately about dogs having similar symptoms eating bags of food sold within the last few months. I called TOTW. They listened to what I had to say and requested I send in a sample of the food to them which I will do. Not sure,what the deal/problem is but I'd be leary to buy this brand right now. It was a great food, improved his coat, enery level, etc. Hope they get it figured out soon!!
