Recently, the dog was suddenly very keen to spend the evening out in the garden, doing a lot of barking. I went out there and discovered the reason for all the noise: there was a magnificent lizard living out there, nearly half a metre long, and the dog was trying to build up the courage to bite it. The lizard was making a deathly noise and inflating itself to look scary. So I started keeping the dog indoors, to give the poor lizard some peace.
About a week later, we saw the lizard again on the road outside the house.
