Okay, I read other posts and this post, and tried the SynFlex. I have been taking it along with my dog for 14 days now. The stuff for dogs is the same as for people. just different dosages. I did not double up the first 10 days on either of us since I have been taking similar supplements for close to a year, and my dog has been taking similer for almost three years.
For me, I have not noticed a difference yet. Of cource I have a large defect, so I am doubtful anything would help. My dog on the other hand is no longer rabbit hopping up and down the stairs, and has gone back to herding all the other dogs, and people in the house (she is a border collie that once worked on a ranch). She has had good spells and bad spells throughout the past three years, but this good spell really is the best she has done in ages. We are currently having snowy very cold weather (14 degrees out), and this generally causes her to be worse not better. I will continue to watch how she does and let you know if this turns out to be a good spell, or if she is actually doing better.
