Freezing for a few weeks sounds a bit excessive. Is it completely necessary? Is it important to thaw the bones before giving them to her?You probably read about Trichinellosis, a parasite that is found in pigs and other mammals. It is recommended that you freeze pork for a few weeks to kill the parasite but in Ireland there has not been any recorded cases of trichinellosis since the late 60's and I believe its the same in the UK. This may not the case on the continent and possibly in the USA. However I do freeze all the raw meats and bone for my dog.
