Hiya! Used to have a dachshund, Fritz. He was gorgeous. Used to bark @ his own reflection, loved fruitcake, chicken & chocolate (dog =/=owner) & let me put my arms round him & kiss his nose.
Then we had a collie, Sam, who weed on said dachshund's head & used to go "woooo" when he wanted a walk. It wasn't a dog howl, it was a human sounding wooo – we couldn't work out why for ages. Mum used to ask him if he wanted a walk, then say "OOOOO you do, Sam -- yes you do, OOOOO he does" & he was copying the way she said OOOO ! Clever Boy! Got collie now, Merlin, who worries if I cough. It's if he knows I need extra help.
