Thanks for the follow up. My dog has been on GlycanAid HA for about a month and it really seems to be helping in her recovery. She still limps a little but I would to if I had the same surgery. She got scared last night during a thunderstorm and jumped around and seem to have strained hurt leg. I have started her on some anti inflammatory and walking her. She seems to be ok. I believe the GlycanAid HA has really helped. I have started my sons Westi on it as well. Thanks for your help.
