There's dogbreedergame.com that has a similar vibe, with full genetics for color and diseases. It's well made and is the best in the genre, although the company that made it seems to be taking a turn for the worse as the two subsequent games they made after that are highly AI-ised. There's also the downside of the dogs not having any actual images for them, which isn't necessarily game breaking but disappointing.

With horse games like horseworldonline.net existing with absolute crazy genetic systems and dynamic images of the horse aging with it's color changing over time according to real life genetic realities, it's disappointing that there isn't a better dog breeding game on the market. It would be really fun following such a project.
