Take torrential rain and one Glen of Imaal Terrier who wants to go for a walk. Glen ignores suggestion that it is too wet. Show Glen dogs of another breed who are refusing to even stick their nose out of the door. Glen raises one eyebrow and says they are ready.
On returning from walk divest owner of waterproof coat, trousers and hat and suggest (again) to Glen it might like to be dried off. Glen ignores you. Blackmail Glen with the promise of a Smacko and towel dry whilst aforementioned treat is being chewed upon. Head, legs and underbody are wet but main body is still bone dry under dense correctly textured hair.
Hopefully the last “coat testing” of the season as a hot summer has again been promised but somehow…..
