My puppy constantly whines whenever I leave so I think I'm going to give it up to a no-kill rescue.
Will you miss the puppy after you give it up?
I will but the separation anxiety it's going through, ugh I just can't handle it.
If you really feel you can't take care of the puppy because of that then you're doing the right thing. A no kill shelter will find a great home for the little guy. Sometimes it just doesn't work out when you get a pet and you're doing the right thing by trying to find it a new home.
Look I just want to do something nice, I don't care what they are going to do with it.
You should care even though you're giving up the puppy. Even if you've realized the puppy needs a new home and that you can't take care of it, it's a living creature and deserves a good life.
