Congrats. Im partial to griffs and some are known to take a little longer to potty train

Be consistent and keep her in the crate. Every few hours and let her out to go to the bathroom , praise her and back to the crate. She has to stay in crate at night until she learns. Its ok to put crate next to bed. Get her outside and soon as she is out of the crate. You can play with her outside.

Never hit a griff or yell too much. Very sensitive breed but also intelligent and very social so need to be around people ( they love kids) and other animals.

Be patient as she will probably have a few accidents
