I'm a few months short of 60 - me and mrs [she's mid 50s] avoided having kids,
so I've never been desensitized by nappies...

The last time anything ever puked, peed, or shat on me would have been my puppy back in the late 1960s...

[ok maybe the mrs when we were students on a binge pub crawl...???]

She, however works with little kids in an infant school
and regularly comes home covered in god knows what...

She's South Welsh, and has a deep fondness for sheep dogs,
in fact we both admire any working dogs.

So I suspect her eventual retirement might involve plans for a rescue dog...???

.. then maybe a ferret or 2 to complete the team...????
