Get Your Dog Care Questions Answered by Experts
The anal glads are located at 10 and 2 (like a clock) beneath the tail. They contain a yucky substance that is secreted every time the dog poops or when they are frightened.
Sometimes the glands get over full and you need to have them expressed. You can use a baby wipe to wipe away some of the goo and it will help with the smell.
Your groomer or your vet can help you to express the glands or they can teach you to do it yourself.
