Little

Sisters can be annoying.

Not his real sister of course( I actually went to buy his real sister 12 years ago but came home with Roo as it was love at first sight)

Bean is his pretend sister, the one that tries very hard to push Roo out so she can win mummy's heart.

But the others actually fall in to a pecking system and realise Roos my first chihuahua and that we have this special bond.

Difficult to explain unless you are a dog owner.
