I have my 8 year old German Shepherd / Rottie cross on glucosamine /
chondroitin since she sometimes appears a little stiff. This is a
relatively cheap brand which is glucosamine 400mg and chondroitin 75mg
per tab. I think Cosequin and Synoquin (much more expensive) are
approx. glucosamine 475mg and chondroitin 350mg per tab.

I now have a six month old German Shepherd with no known problems with
arthritis. A woman in the park with a similar age Shepherd tells me
she has just put her girl on Synoquin as a preventative measure, as
recommended by her vet.

I have not heard or read about glucosamine / chondroitin being using
preventatively for puppies before.

Has anyone else put their puppy on this or know of any research that
suggests it is beneficial.

I am of course keen to do the best for my puppy but also understand
that drug companies can be keen to sell their products too.

Thanks, Mike
