Just to throw in my two cents… trichinosis is almost completely unheard of in modern, first world pork products. You can cook pork rare for yourself or family without worrying about it anymore. Same goes for your dog. The advice on freezing for a significant time is also good unless you are serving walrus or polar bear.
My dogs don’t do very well with pork as a protein source, so I don’t serve it only for that reason. I don’t think it is harmful in itself… it’s just that people are only now starting to include it and the old fears are still there.
