First and most importantly we hope your dog is feeling better. We'd very much like to speak with you to better understand and would ask you to call the number on the back of the bag. Most likely your dog was over eager and ate too much of the rawhide too fast which is why we always encourage monitoring your dog to ensure that they don't get too excited and eat too much. We hope your pup is back to normal and again we would love to speak with you as you are able to call our customer service number.
