Touch Pets Dogs is a social virtual dog simulator at the most basic level. Adopt a dog, and do everything you would with a real dog including petting, fetching, chasing and anything else you could think of.
The game is free to begin with, and it's your choice to buy food. The food can be bought from $0.99 to $29.99, with each value giving you bonus food bowls at launch. The game is based on energy just like Eliminate, and it slowly recharges during the day.
Fedding the dog some food gives it energy, and with the energy you can interact with your dog. Without the energy you can't play the game, as your dog only sleeps.
