They have several breeds at the moment and recently, they are allowing people to breed their dogs! But you have to breed the dog with a litter license.

The currency: FooGems and FooDollars.
How it's used: FooGems and FooDollars are used to buy accessories, backgrounds and food for your beloved dog/cat. FooDollars are also being used for litter licenses.
