I have a greyhound and she is an extremely timid dog. However, ambulance/police sirens send her wild - she howls so loud and won't stop for ages. It's quite embarassing when it happens on a walk :P Also she howls at ice cream vans sometimes, and also if you play the harmonica
(Original post by Perky.) I and my cousin love to keep kittens or cats. I genuinely abhor dogs. Once, my cousin's kitten ate chocolate and got died. Alas! She is inanimate anymore because chocolate is toxic for cats.
My dog howls at most things... Any loud noises outside the house, if you leave him shut in one room accidentally, if you say certain words (I swear sometimes I think he can understand English). I think it's just what they do!
