"The Boys" run dog agility every week and therefore are subjected to a lot of joint banging. We were told at an early age to feed Nupro Silver every day, which we have done. I have seen 14 year old labs that have been on Nupro be very agile and in great health. I certainly believe in it.
And yes, they can certainly be The dogs from 4377( turn this upside down) on occasion.
