I do not see any problem with rawhide. I give it to all my dogs. You have to pay attention to make sure they do not swollow large peices. I prefer either chips, or rolled. I never use any of the knoted, as the ends can come off. I also choose only USA Made rawhide. I purchase mine through a company online. PM me if you want the website. I am not sure if I can post it here.
to much rawhide at one time, or biting off and swollowing large peices can cause intestinal blockages. You have to know how they chew before leaving them alone with rawhide.
