I dare not confess 
Darling Boy is kept at livery at the most amazing yard I have ever found. It's actually better than having him at home as the yard owners are lovely and an amazing font of knowledge.
Anyway, a little coloured cob colt came to the yard (sort of rescueish, bit of a long story that I can't really go into, sorry). Yesterday we gave him a tail wash as it was awful. And the most godawful thing I have ever seen happened.
He seemed very sensitive round his dock so we started to very very gently comb out the area with a wide toothed come. Have to stress that we really were incredibly gentle, but the whole area was so matted that we couldn't get to the skin to see what the problem was.
And the end of his tail sloughed off. In our hands. It was so matted that the skin had pulled apart and caused an infection. Poor, poor little boy :(
So I bought him off his 'owner' for absolute peanuts. Today we gave him a full bath and discovered that he really is quite lovely underneath. Very well behaved now he is out of pain. He has seen a vet and is being treated. He now has a lovely deep bed, rugs and is going to be as well looked after as I can possibly do.
And I am now the proud owner of a potentially very lovely looking coloured show cob
