Those who suffer with it will know what this means. It's not good . It descends like a black mist or the analogy I like to use is a drop of black black ink ( gone a bit Dylan Thomas there ) in a glass of water.
So, if I'm going to have to live with my own black dog I might as well give it a name. I'm thinking of Shaggy ( too Scooby Doo ? ) or Baldrick or maybe something human like Percy , yes Percy is good - slightly silly, slightly squiffy a bit toff like.
I'll then have to buy it one of those long plastic scoop things that you a fling a ball with. They hadn't been invented in my dog-owning days , more's the pity. I'd scrunch up my blackest thoughts into a ball shape and fling into the middle distance where it would lie undiscovered for months.
Then of course you'd need the pooper scooper, the personalised dog bowl , the woollen car rug for those damp dog walk days and a squeaking rubber chicken. With that lot in tow , I couldn't help but cheer up = job done.
