content: My Rottweiler is allergic to almost every animal protein on the planet. So far, he is doing ok with whitefish and salmon. That is why this treat is so good. It does smell strongly of fish, it smells good. Its got a crunchy texture, its unlike any other pup treat I've found. My pup loves it, when I take the bag out of the pantry he runs to the kitchen and sits for his treat. Don't even have to call him.The 28oz resealable bag is great, the treats last a long time. If your pup has allergies, you may want to think about giving this one a chance. Guaranteed, your pup will love them.
