Doggie siblings are just like the human kind. There's always some kind of playful competition going on; one sib teases the other, there's a lot of noise, and one of them is always looking to mom and dad for some kind of help.
These two West Highland terriers are named Madison and Riley, and they're quite the duo. Madison is the older one, the dog who starts the action by barking furiously at the cushy bed. And then out pops Riley, ready for a spirited game of peek-a-boo. Watch until the very end, when Riley really surprises Madison!
