Crying here, too, Angela. This is the hardest part of owning a dog, and I am so very sorry you are at this point.
Most of us have been through this, too, and now that I know the bond one has with a GSD, to go through that with this breed must be heart shattering.
We are here to give you a shoulder if you need one.
Be strong for Zeke. It's what he needs you to be, for him.
