Awful tale
with a good ending for the pup, as you say hope Frankie is ok
I am having similar trepidations now as our dogs (Sophie and Cooper) just had their first litter.
We'll be keeping at least one (probably 2) of the 6 but I too will need real convincing that the new parents will be serious dog lovers and responsible.
Some people jus cant be trusted but identifying them is the real challenge
