You can always have a back up plan for your littles ones.
Something like this.

I am the back up for a friend of mine the is 25 years older than I.
When they adopted a older dog we signed so they could get the dog and feel
confident that their loved one would be taken care of.
The 1st dog as now past on. We have now adopted a 2nd older dog with them.
Older dogs are hard to place. Many recuse will work out a plan like this with you.
