Ok so I have seen on this site that rawhide = bad, bully sticks = good…so out of curiosity and care of my dogs health I went to the specialty pet store and asked if they had some. I also asked what they were made of :eek: now I wish I had not, because now they are sitting on my living room carpet and all I can think about is what they are lol...as long as the puppies like them I guess it's all good. I also got a few other parts that the lady suggested. They came in a mix bag, so if you have any suggestions of which parts to just throw out let me know, a few I have seen so far in there are pig snout, cow ear, esophagus, thendons, etc...They seem to be happy with their new treats, and so will the chairs and carpet lol. Oh and all the treats are Merricks brand, so I trust they don't have any of those funky perservatives like formaldehyde in them
