self-expressing anal glands
boy am i grateful for the search function on this board! i have a friend's cavalier staying with us for a couple of weeks. tonight i was brushing his tail (which is far more beautiful than either of my two's tails) and i noticed a very unpleasant smell. upon checking further i found that his anal glands had emptied. i was worried about this and was checking all sorts of sites thinking i had an emergency on my hands. then i searched here. i will watch him carefully in the next few days, but i'm pretty sure it was the same reflex you had seen.
