It doesn't matter what breed that she gets, because from what I've read of her, it's likely she would end up dumping the dog in a shelter in a relatively short period of time. Reasons: doesn't have the time or patience, costs to much to maintain (food, vet, toys, and various never ending needed supplies), pees on things, poops on things, chews things up, won't listen and behave, barking is annoying - and those "reasons" are the tip of the iceberg.

This person DOES NOT need a dog in her life at this point. Maybe someday when she grows up and becomes more responsible, she MIGHT be ready.
