Hi Cocnee.
There's no need to post the same across different forums, so I'll leave the second one that's in the correct place, but the dupe has gone

As to the Q at hand, I'm afraid that I've never played that game, but if you are trying to "start over" with a new dog anyway, it might be worth trying to delete the savegame on the cart (from the menu) or starting a brand new game and overwriting the previous save (may well be a corrupt save at fault here).
This way, you'll have a new save (that shouldn't be problematic) and she can create her new dog as she wants
