Hi, It is not a good idea to feed frozen bones of any type. The temperature can cause micro fissures in the enamel surface of the tooth.
If one considers that an adult Berner can exert 800-900lb pressure per square inch one needs a yielding bone ie a crushable one. Solid centre cut marrow or shin bones are not generally going to break and the tooth is smaller than the bone and more likely to crack or break off with the equal and opposite force. (Been there done that and paid the dentist bills) Fine if you have a gentle nibbler but the majority of my dogs go at a bone like its their last meal on earth, chewing sets off the endorphines and the dog can become somewhat entranched and will not stop chewing even if discomfort were to happen. Some dogs can become quite exhausted and then want to drink a huge volume of water, so supervision is required for these types of chewers. Rose Tierney
