Why does my dog's anal glands leak randomly when lying down?

Updated On September 23rd, 2025

Pet's info: Dog | Redbone Coonhound | Male | neutered | 2 years and 4 months old | 78 lbs

My 2 y/o, male, coonhound mix has always had this "issue" since adoption over a year ago. He frequently, unintentionally expresses his anal glands at seemingly random times (mostly when laying down indoors once every 2-3 days). Since he turned 1 yo, I've Fed home Purina Proplan Sport. I've experimented with other Proplan variations but haven't had any luck. He currently has a yeast skin infection (1 wk) on his [legpits?] which is clearing up with medication but I think this is unrelated.

Handsome boy! Expressing his anal glands is normal. Most dogs express the fluid when they defecate and also if they are scared or injured. Since this smells bad it’s unfortunate that he does this in the house. I don’t know of anything that will correct this. I like Purina foods and he certainly looks healthy so I don’t recommend changing the food. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Moose.
