To My Dog's Previous Owner:
My family was never expecting to get another dog so quickly after our previous dog's unexpected passing, but when you left him at the animal shelter with no name and without a care of where he could end up, you changed our lives forever. He was on the verge of being euthanized, and someone came along and rescued him in an attempt to find his forever home. We saw him, we talked about it for less than three days, and we decided we were going to be his forever, the family he could grow up with, the family he could snuggle up to at night, and the family who let him run around in the backyard without a fear that he would ever be abandoned again. He fit right in immediately.
His happy personality, his want to always be around people whether that be on the couch beside you, snuggled on your lap, or laying next to you in bed, and always wagging tail was bound to put a smile on anyone's face. Though he was known as "no name" for a while, we finally decided on a name: Henry. Henry now knows the sound of my car when I pull in the driveway, and that the jar on top of the microwave means treats, that he gets a big bowl of food every morning, and cold water from the filter. He is living the life that you should've given him in the first place. He wants to be everyone's best friend, including the unimpressed cat who is just now learning to tolerate his personality, which is the polar opposite of hers. Your selfish act resulted in one of the happiest times in my family.
