:(

So guys,
This app is very new. I dont work there, but its only at version 1.0 , so it is very new.
Dont be afraid if the game wont accept your name, the name you out is either in use, or somehow they find it inappropriate.
Also, your dog needs to get up to level like 200 of affection to learn the hardest or best trick, roll over, so it might take a while.
Also, I think they are just testing the app and thats why it wont let you switch yet.
Also, I know things are very over priced but once you get to a place where you can have more than one dog, it makes competitions so much easier and things so much more affordable.
Yes, the dogs are over priced because they want you to buy their merchandise. And yes, the merchandise is very over priced because they want money. Some people make a living off of making apps, you know.
If anything Ive written makes you upset dont take it out on me. I could be wrong I dont even work there.
Hope I was helpful,

Just call me leopard about My First Dog., v1.0.1
