That might be what they're sniffing, but anal gland secretions are not subtle. They're the opposite of subtle.
I have a lot of dogs. Every once in a while, it seems that one of them gets a plugged up anal gland, or it doesn't get fully expressed when they poop. An earlier commenter said to look for liquid dropping out when they poop; I see this all the time. But sometimes that doesn't work for whatever reason, and then later on the gland "pops" and all the stuff comes out. The dog is usually sitting on my lap when this happens. It happens with both girl and boy dogs. My wife calls it getting butt-juiced.
The smell causes me to immediately change my clothes. It's not a fecal smell. I can't begin to describe it, but once you smell it you'll never forget.
Years ago we fostered a girl dachshund who loved my wife but hated me and feared me like the devil himself. Often when I would approach her in any but the slowest and most non-threatening way, she would tense violently and squirt anal gland juice like a skunk. Sometimes she'd leave a trail of the stuff on the floor as she ran for her life. One whiff would tell you it wasn't urine.
(BTW, that poor girl dog was eventually adopted by a sweet single woman and they are now inseperable companions)
This is true. I meant that they are subtle in the amount available when dogs butt-sniff each other. Dogs can detect the tiniest amount, way before a human even notices it's there. The concentrated stuff is, as you say, very intense.

I'm sorry to put this in your head but... fish sauce.
With really old dogs the gland sometimes won't unblock itself and becomes infected. The cure is to milk it. This is a vet's least favourite job, and they have some pretty grim tasks.
