This is explained partly by natural healing and partly the placebo effect. In the placebo group, however, no further improvement was noted after this point of time, whereas in the mussel extract group the percentage of the dogs improving increased until 74 percent. When the dogs which had been on placebo until day 56, were put on mussel extract supplementation, the percentage of healing increased to an average of 91 per cent. The degree of agreement between the owners and the clinicians on improvement of the clinical condition of the dogs was very good, and suggested that, in general, treatment of arthritic disorders in pets may be determined as being successful or unsuccessful on the basis of owner observations.
This study confirms the results obtained earlier in a multicenter study conducted by veterinary clinics in Japan, where 90 per cent of dogs and cats suffering from arthritis improved when supplemented with New Zealand green lipped mussel extract.
