I would be wary of giving my dogs Glucosamine after my experiences with it some years back.
I have osteoartritis in most major joints, left knee diagnosed age 20, as a nurse of nearly 40yrs in the job majority before there were any lifting aids my joints have taken a hammering so decided to try out this drug that was being raved about, luckily a friend had done the trials on her patients and warned me that quite a few developed diabetes which disappearred when the drug was stopped, I tested my blood weekly and for 18 months everything was fine, joints were not as good as I was expecting them to be but I carried on, then my blood sugar started to climb and even fasting ones were elevated so I decided I didn't need any more problems so stopped the Glucosamine and my bloods returned to normal and remain so today.
In 2006 I was told after internal inspection of my knees that I would be in a wheelchair within 2 yrs.[10yrs too young for knee replacements], I am still working 30hrs a week on a busy ward but now need heavy duty pain patches to get me through. My dogs give me a reason to keep myself mobile too.
For all the speciallists I have seen not one has mentioned starting me on Glucosamine or the likes which makes me think the medics don't have much confidence in it.
