I've had my share of whiffs of stank dog halitosis, though I'm pretty sure that they weren't built to smell pleasant to human beings.
Stank Dog Halitosis, good band name.
Dogs seem to think anything that's horrific in odor is great stuff.
Case in point, had a pair of sneakers that'd curl hair and peel paint.
The dog would roll on them as if they were Chanel No5.
Roll her eyes up in her head, snort, and flop like a fish on them, and growl at me when I tried ot put them on!
