I initially started buying Dingos Rawhide - Minis as a result of my dog's veterinarian. He had a need to chew on something - she said that all dogs have an instinct to chew. Besides that, they are rawhide so I figured it would keep him quite busy and away from the shoes. It is very funny to watch him hold it down with one paw and chew until he's tired. The Rawhide Chews have meat on the inside of them and the minis are a perfect size for our dog Bolo. I know that giving him the Dingos Rawhide Minis is not limited to simply being a treat for him but it also has some health benefits for him as well. I regularly purchase them about every 6 or 7 weeks. I like how they come in a resealable pouch type bag, it makes it easier to keep them fresh. I don't think these should be used as a method for training your dog through treats. It doesn't work for my dog anyway. Mainly because they last a bit longer than the average dog treat. It takes my dog quite a bit of time to really get to wear one down to the meat. That's also one of the reasons I like this particular type of dog chew. They aren't very expensive and the last. Also I frequently see and use coupons for these - at least in my area, so be sure to check for coupons too.
