I do mine myself, but hey i was a groomer for 10yrs

i empty them from the outside, but most vets at work empty them by inserting a finger gently and doing it form the inside out

Whatever your method please beware of the brown liquid and aim away form yourself...believe me the is no smell worse to get on your clothes or god forbid you face

Got to say tho that Otis' A/G were terrible as a youngester as well as have the most awful skin problem....I had him blood tested for allergies, which showed that he is allergic to most meats

changed his diet and his skin and a/g's have been fine since
Good luck whatever you choose
