4 month old female chorkie puppy

I have a female chorkie puppy, four months old, she was born on April 19. She's up to date on all of her shots. Because of my heart condition, I don't have enough time for her, and it's not honest to her, she's a good dog. Not chewing, loves cuddling, good with other pets. Rehoming $250 fee to make sure she comes back forever to a nice family.
