My dog always goes along on competition, but he has osteoarthritis. Do you also have something for that?

Yes, for dogs we have Arti-Gold-Canine. A pot of 126 tablets, of which you administer 1 tablet per 10 kg of bodyweight.
As a matter of a fact, we also have a product for humans with joint pains, you can find it with the name Arti-Forte or Arti-Forte+.
