Touch Pets Dogs (Free)
Real dogs are a lot of work and you can’t train them to be doctors. Virtual dogs, however, are a different story. For the animal lover in your house, Touch Pets Dogs allows users to adopt a dog and train him to perform awesome tricks, or prepare for wacky dog careers. The app can be played without spending additional money, however be aware that in order for your kids to really grow their puppy empire, in-app purchases may be requested from time to time, ranging from 99 cents to $2.99.
