So the hubby noticed yesterday that Chaos has been scooting a time or two on his bottom. I'm new with all this anal glad stuff. Does this mean I need to take him in to have them expressed? He is suppose to go back Monday for a recheck on his ear infection, so is it ok to wait til then or should I go ahead and take him? Also, is there a way to tell if they are full other than when they do the "butt scootin boogie"? 
If you can have your vet teach you how to palpate and express the glads yourself. For the price of some gloves and K-Y you will save lots of money on your baby. It's not a hard thing to learn.
