Do they all contain the same dogs and are the games identical in their content?
My daughter currently has the labrador version and i was thinking of maybe buying her another on for christmas. Needless to say if they are the all the same, i'll save my money.
They all contain the same breeds - each version starts with 4 or 5, but your daughter will unlock all the others one by one as she earns trainer points or finds rare items while walking her puppies. So save your money ;-)
