Hello Dr. J.,   Our dog Akilah, a husky mix, had a badly broken leg when we got her as a puppy and she is now 3 1/2 years old.  Her leg healed after some major surgery, but it has never been 100%.  We have given her the GlycanAid HA for about 3 weeks and we can already see a difference! She is running longer and faster, and pulling harder (it’s a hard habit to break in a husky!) then she has in a long time.  I look forward to seeing her progress in the next coming months. Thank you for your product!
