Oppinion of the vet on glucosamin is that it is of no use in this case because it is not a joint problem but a growth problem in the middle of the bones. Any opinions on that?
I would disagree with that opinion. Joint support supplement in large breeds is not a bad thing. Though the supplements may not directly treat the HOD problem is can still benefit the dog when it comes to joint development. You may want to also try about 2000 mg or vitamin "c". We have some articles about the benefits of vitamin "c" on here also.
