To find the anal sacs, lift your dog's tail, and look in the four o'clock and eight o'clock
positions around the anus.
When the pea sized dog anal sacs become swollen you can physically feel them in them by touching the glands which are at the 5 and 7 o'clock
positions around the anus.
The sacs will be in the 4 and 8 o'clock
position around the anus.
