It is strange because I can find plenty of reference to to products containing calcium carbonate 700 mg and magnesium hydroxide 300 mg but I can not find any products for sale online with that combination (I checked PetCo, PetSmart, CVS, Walmart, Amazon); plenty with 1200 mg, 600 mg etc... I would ask your Veterinarian about local stockists for this since he is making the recommendation, plus I don't know which country you are in. (wagwalking.com)
I'm excited to announce a new local stockist of my Hand - Meyd bath and body product line! (hand-meyd.com)
Visit the magazine's website to find local stockists. (vitrinegallery.com)
