Zuke's Mini Naturals are perfect for training because the dogs love them. We have two dogs a chocolate Lab and a Lab/Golden Retriever mix and they both work hard for them. They're also great because they're so small, you can give lots of little rewards without overfeeding the dog. They come in several flavors which is also great because one of our dogs can't eat peanut butter and almost all treats come in a peanut butter flavor. They also don't leave any smell or goo on your hands. Aside from whats left from being licked by the dog. They also are generally very reasonably priced. I'm eager to try...
