Oliver heard the documentary "A man among wolves" and fell in love with the sounds of the wolf howl. So now I have the sounds of wolves and cubs most of the day. Honestly, he never howled or made puppy noises (only barked) before the show.
I know he had dogs in his life before, so I wonder if there weren't puppies involved, because he really really loves the wolf sounds.
He has not forsaken the farts however,only now he laughs, then howls, THEN farts. Variety is the spice of life.
I'm going to try and record some of his funnier moments-because I wish you all had a playback of it that you could play whenever you get stressed or grumpy. It's truly better than drugs.
