[Hound Dog Mom]

Hey EHubbman –

Glucosamine and chondroitin are fine for puppies. A dog’s natural diet (raw) would be very rich in glucosamine and chondroitin as cartilage and bones contain high levels. Dogs foods, even those with added glucosamine and chondroitin, don’t contain enough to say so – so I wouldn’t worry about it’s presence in a kibbled dog food.

I have not been able to find any evidence suggesting that supplementing a large breed puppy’s diet with glucosamine can be harmful, however I don’t believe it to be necessary either. My two get lots of RMB’s so I know their diet is rich in glucosamine and chondroitin – I probably won’t add any supplements until they’re seniors. I do, however, typically recommend that large and giant breed dogs eating processed foods receive supplemental glucosamine and chondroitin (or whole foods providing these nutrients) starting between 1 and 2 years of age (when they’re young it can be a low dose, just for maintenance).

This is an excerpt from an article about large and giant breed puppy nutrition written by integrative veterinarian Dr. Susan Wynn:

“There are no studies so far that indicate whether it is effective or harmful to supplement with glucosamine to large breed puppies because of their risk of DOD. In general, I wait until I recognize a risk factor in a dog.”
