My dogs got sick

Let me start off as I am very upset. I buy Pedigree dog food for my three dogs. One of those dogs is a 14 week old puppy. I know I shouldn't feed puppies regular dog food he has a mixture of puppy food and big dog food cuz he is not like the puppy food anymore. My dogs have not been feeling well for the last past few days and I wondered why their stomachs were so upset. Well I got to the point where one of my dog was not eating just normal amounts of food that he's used to eating. He's a big pitbull so he eats a lot and he's always hungry usually. So I checked it up to him just having a tummy ache not hungry stuff like that, but I started noticing my other dog started not feeling well too. So we have used only three to four bowls of this bag of dog food that's equivalent to two days of eating one dog. I go to feed my dogs last night I scoop up one of their food, and the food is stuck together with blue mold. I just open this bag of dog food two days ago. I am fucking disgusted so I get another scoop of dog food out, and you'll never guess what I saw. I saw living crawling maggots. My dogs got so sick from this dog food I always USED to buy them I had to take them to the vet. Long story short do not buy Pedigree dog food it used to be the only dog food my dogs would eat, but I will not buy from them ever again.
