Have you seen my Sweet Puppy Girl over in the left column? She's a great pet. No buying food, no paying for vaccines or medical care, no poop to clean up! The Perfect Pet!
Have you played with her? She will do tricks. All you have to do is click on the biscuits, then click high enough to make Sweet Puppy Girl jump up and grab it. She'll even bark for you to say thank you!
(She's OK, honest, but I've been having a POWERFUL desire to get another pet. I must resist...)
