Re: Hair loss and a few new photos :)
It looks age related fidgett. The skin looks healthy and not red or anything. He looks to be in mount too so it may grow back a bit as his winter coat comes in. You could try adding a spinkle of debittered brewers yeast to his porridge as this can help coat condition.
Just butting in - I was looking for Debittered brewers yeast for Daisy as she is losing her fur a bit, but could not find it in Hollan and Barrett - what section would it be in? (the shop was very busy and I was in a hurry so couldnt ask anyone at the time)
