Similar to what Crystal said - I wouldn't necessarily supplement unless you have a specific need. I would definitely not give bone meal - as this will throw the cal/phos ratio way off, if the diet is *already* balanced.
More and more canine nutritionists are now recommending a probiotic and digestive enzyme -
no matter what diet you're feeding. In fact, I'm no longer hearing *not* to give one. This could be due to 1) the benefits they're seeing, even in healthy dogs who eat premium diets and 2) the belief that many dogs' systems are vulnerable simply due to generations of increasing immune issues (possibly due to overvaccination and other things). So, my loooong point is - a probio/zyme product could be beneficial, even without obvious issues for adding them. I am liking
this one (it is microencapsulated, so it does survive the pH)
I've also decided to give my guys
Vitasorb every 14 days, bc right now I have them on a Duck Offal diet (Marcel is having skin issues).
If there are skin issues, that's a whole can of worms - but sometimes there may be a fatty acid imbalance
due to that issue, or
causing that issue.
If your baby has hind pain, I'd get the vet to diagnose it - just so you know what you're facing here. And I agree w/ Crystal - Cosequin is a good one for joints.
