I know tripe is supposed to be really good for them but is it really good for any particular problems? For example, I have a senior collie who is really having trouble on the stairs and I am looking for something to help with the arthritis and not only that, from years of eating kibble (I have only recently switched to raw and unfortunatly, she has paid for my ignorance

) her teeth are not the best. Although I have seen a HUGE improvement in her teeth since we started raw in April, I would like to continue to see improvements and it seems like things in that area have stalled. If not the tripe, can you suggest anything else that's out of the ordinary? I'm feeding chicken with bones and pork with bones at this point. The only beef I've fed is without bones as I'm afraid those bones are too dense. And ditto on the lamb (although they don't get that very often since it's so expensive) I've also fed some fish but not sure that it helps clean the teeth and it's not the most popular with my girls either. Thanks for any advice....
