Hello Amy
I suggest that if you wish to see your friend, go along and then when you get back home, go straight to the bathroom, wash your hands and change your clothes before petting anyone.
It would be the same if you were to visit different breeders - we prefer people not to visit two on the same day for that reason - usually people have a wash and change from one day to the next so germs from one area are not transferred to the next.
Hope that is ok.
