Just for those who are less adapt to chemistry, glucosamine comes in to forms sulphate or hydrochloride |
One needs to keep in mind when compering results, oral doses & intramuscular doses is like compering apples to oranges especially with a polysulphate
From an oral perspective I have little experience with horses as I mentioned earlier but I do know that in general dogs do respond well. However, that is a different species!
I have also seen good things with cod liver oil in dogs as a preventative measure... at least certainly with my own dog who being part labrador is prone to arthritis. We got him when he was between 4 and 6 (rescue dog) and gave CLO on a frequent basis; he is now between 12 and 14 and there has not been a hint of arthiritis! There are a few other people in my area who have done similar and have also had favourable results. However, as I have already said - dogs are a different species!
