Snooze, you lose 
Max was picked up yesterday by someone else....I sure hope they give him a great home.
I prefer to look at it another way.... Max wasn't the one. There are a crap-ton of other dogs for you to rescue.
Look at the Buster Foundation, bully breed rescue, they had some Rotties.
& if you would consider a Black Lab.. I know where you can find a 6yr old female,with vet records&pedigree papers, who's a total sweetheart. She does need work, but most rescues do.
