Our 4 year old huntaway cross has bilateral elbow dysplasia, he recently had a double arthroscopy, this has helped, he has hydrotherapy every 2 weeks now and I put him into jointsure as it's ingredients are so similar to that other well known one!. I will say that I have used them other one years ago(before they went silly with the prices) and don't it very good, I couldn't justify spending£300 plus for the same amount that cost me £70 from jointsure. I had trialled jointsure for 3 months before buying the 900 tablets, they work just as well, our dog has 2 to 3 hours exercise a day and this product really makes a difference to his mobility. Hunter is not on any other medication and I am hoping it's a long time before he needs anything from the vets. I am very skeptical about claims that companies make with products but this time I am pleased to say that it really does seem to help his condition and in my opinion works very well. Last hydro session I didn't say anything to the therapist (but I had noticed the dog was moving better and was more fluid in his movements), I asked her to examine his right leg(which even since the operation was still inflamed although not massively), the therapist told me that his inflammation had gone to virtually nothing and was very slight, I then told her I had noticed an improvement, hence why I wanted him examined. I will continue to use jointsure with the blue label probably for the rest of the dogs (hopefully) long live and I just hope they don't go silly with prices like the other place did.
