Is she taking the pup out every half hour or so?? I agree w/ Orangutango, she should keep the pup with her on a leash or be watching her at all times. She should also being going outside with the pup and making sure she goes potty before she comes in. After every meal, nap and play time, the pup should go out. Both my doxies were never potty trained... they are a bit more difficult to potty train. If your friend is being constant about it, and watching the pup always, then I'm sure she'll be potty trained in no time.
