Over the course of a few months, our (9?) month dog has done this;

This caused=

chewed up one stick of both pairs of drum sticks for Rockband/ GH
(useless and different sizes making hard it to use efficiently)

The Rubber off both analog sticks to be chewed off leaving the sticks bare and a pain to play with
(buying a new DS3 with Uncharted 2 hopefully soon)

How i met your mother season three with chew marks on the case
luckily no damage to the discs but the case annoys me

thankfully he hasnt decided to go after the God of War III media pack, since according to ebay, its worth more than my ps3 :D anyway there's a short update, ill blog soon with exam results, which should be next week. Have fun.
