I ordered these for my 12year old pup a few months ago and continued ordering bc he loves them. I may have reviewed these treats in the past…I cut them into small pieces to last a little longer as they are expensive. They always smell like as I think they should. However, I finally took some time to read the ingredients and saw that these are radiation treated, which supposedly is safe, but questionable if it’s from China. Now I’m hesitant to order them again. I admit he seems fine after eating them but I’m afraid what could happen in the long run. Just my thoughts.
