How to play: First you need to feed dogs then read how to play it, then when the dogs turn green put them in the hospital. Then if 1 of the dogs die put them in the garbage. But then if you want to get more dogs then click the paw button like the red paw up on the screen. And then keep clicking the red paw until it turns red. Because red is the limit. And then if you want to make money then you need to sell your dogs right next to the hospital and then you earn some money. If you want to make diffrent dogs then, you need to have the same color dogs then mix them up, to earn diffrent dogs. And if you ever want the limit level, then the limit of mixing dogs are level 8.: Hope This Helped Thank you for your time :)
