No, these are not super sturdy, or for heavy chewers, but...These little super squeaky pigs are magic for rewarding my Aussie (in the picture) when we work agility.They are a super high value toy for her, and I only use them when training weaves and distance. She loves the size, the squeak, and they fly through the air as if they have wings!The fact that we get ten in a bag and average out to less then $3 each makes up for the fact that they are not the hardiest of fellas. Since we only use them in agility for particular training sessions the bag of pigs lasts us a long time.The pigs have also managed to capture the interest of many others in class, so with ten pigs in a bag we can also share the magic.If you are looking for a toy for a chewing these are not them, but for training and smaller none aggressive chewers these will fit the bill.
