After my dog’s surgery, you sent me an email and video about the use of this product.  Daisy was still limping after 12 weeks recovery.  I purchased GlycanAid HA, and she has been taking it for four months.  After a few weeks, Daisy’s limp was gone.  I intend to keep her on this supplement to prevent other joint problems.  It is great and I have recommended it to others. Thanks!
