I want to mention that unlike prescription remedies such as
Rimadyl that work immediately, natural products in large
dogs, initially take a few weeks to "kick-in".
In my experience, natural nutrients for many dogs, have proven to be extremely effective in providing relief from arthritis pain. In some dogs, they may be initially used along with Rimadyl. Once a therapeutic blood level of the natural nutrients is reached, the Rimadyl can be weaned down and eliminated.
