I have this on auto subscribe and enough time has passed to give an honest review. Lulu is an older small pom mix, I think. She developed a floating patella which made itself known by the sound of a clicking noise when she walked. I saw this product and I’m all about natural and great ingredients so ordered. She has had no adverse effects from the ingredients and I add it to her food and mix it in. It’s been a about a year now and no more knee clicks and on top of the knee issue, she developed a torn ACL and with the aid of a small leg brace and the daily Hip and Joint Support she recovered from that much faster then what my vet anticipated. Now all of my three dogs get this product daily, one with what I believe has a small occasional trachea issue from birth, but with this product that issue has become much less noticeable and incidences spaced further apart. I will continue to purchase and add daily to their supplement regime as a preventative. Like all new foods or supplements given to your pets, add a small amount daily and work up to the full dosage based on weight, then give it some time to kick in. It was around the four month mark that I noticed the difference.
