Oh goodness, bless his heart. It's so sad that people do this to dogs/cats and he's such an old baby. I would take him in a heart beat!!! Is he at a rescue or a shelter? If he is at a shelter will they put him down? If so, when will that be? You should go get him
I know that's not what you want to hear but I just had to say that. Congrats on the upcoming wedding!! ENJOY!!
