Some of the top game on the website PlayFirst Games are Diner Dash, Deep Sea Deli, Cooking Dash, Wedding Dash, Hotel Dash, Mall Stars and SpongeBob Diner Dash.
Doggie Dash is a challenging new time management game set in a busy pet spa and based on the wildly popular Diner Dash(R) series. It further expands the Diner Dash world by introducing two new entrepreneurs, their furry friends, and more backstory on Flo as players get to meet her faithful retriever, Skillet!
There is relationship between them as they are both made from Playfirst but if your talking about how you play then well in doggie dash you have to bathe cut groom dogs as in diner dash you having seat serve and clear plates. Hope this helps to anyone you needs it. :)
