It depends, most people are afraid of Shadow because shes a Rottie and when shes wearing her halti they freak out thinking its a muzzle...there have been a few people approach me when I'm walking the Jack russells and people generally don't get very close but look at them from a distance And most people aren't afraid of Jack, usually only little kids because he loves to give huge sloppy kisses and kids are the perfect height for him.
