The Dog share didn’t work out well in the end.
For a start, Dog — no mean manipulator —
cadged extra rations in Home A, so that Home B
was obliged to act the disciplinarian.
Then there was the quasi-polite dispute about
the missed flea drops and the bitten house-guest.

Goodwill flagged, and it was decided to scrap the
whole idea, and arrange for Dog to live in
Home A or Home B.
