I want a dog to be adopted today and I want the adoption to fail and for him to come back
Why would you ever wish for a failed dog adoption anyway.
I really want a specific dog and I feel like other people are going to adopt him before I get the chance to.
New dogs are so much fun, but you can't expect a shelter dog to be available at any time that you decide to adopt. Let the dog go with the other family and be happy for them. You will find a dog someday.
But...I want my dog today.
Well maybe you can buy the dog on credit or something like that if you can not afford him. This could really be worth it since dogs make great family members. Getting a dog can be a great investment in your mental health!
