Hello all of my fellow dog owners! I have been looking for good chews for my little pups that will take them a long time to chew, but not be rawhide. I thought I had what I was looking for in Smartbones, but then I found out they were made in China. Is there something like Smartbones that will take my pups a good 10ish minutes to chew through but isn’t rawhide? They are little Chihuahuas and I would prefer something that is not a bully stick or antler, made in the USA and maybe with a knot so that it will take a while for them to chew. Am I looking for something that doesn’t exist?
