I watched a programme about weird pets and a lady had a huge rodent that was larger than a big dog but apparently the same family as a hamster. It started squeaking and my dog shot out from under his blanket and ran around the room and started sniffing the tv looking for it!
He doesnt tend to respond to animals, although his ears would prick up when paul o gradys battersea programme was on. If he hears someone knock on a door on tv, anything squeaking or the sound of bells (like a cat collar bell) he jumps up to find out where the noise is coming from.
