My boy will be 9 later this month (how did that happen?). So as a preventive against aches and degradation I have started him on a supplement - green lipped mussel after seeing a truly transformational change in a friend's dog who has hip dysplasia; and a bioflow magnetic collar. Over the last week he has been prancing about, running zoomies, playing like a puppy, chasing imaginary cats away from the garden. I am delighted. But exhausted! Long may it continue.
