Van roll-call

Six went out. Did six come back?

It sounds like a question nobody could get wrong, and it is the one that wakes walkers at three in the morning. A crate door that did not quite latch, a dog that slipped out at the last drop-off, a busy Friday and a head-count done from memory in the rain.

Counted twice

Out of the van at the start, back in at the end. A walk will not close while anybody is still out — that is the entire feature.

You cannot count back a dog that never went out

That is a miscount at the start, not a successful return, and accepting it would make the record agree with itself while being wrong.

1
Count each dog outAs it goes in the van.
2
Count each backAt the end, before you drive off.
3
Close the walkIt will refuse while anybody is missing.

FAQ

Is this not overkill for two dogs?
For two, probably. For six on a Friday in the rain it is eight seconds and the cheapest insurance you will ever buy.
