First of all- This is VERY generous of you, Julie. I admire you for this. Great job!
Do you mind if I copy you and do that same?

I think a shelter would be better because the dogs in rescue get fostered, played with, cared for and everything as to when the animals at the shelter get no attention whatsovever. Only at feeding time, and if someone wants to play. Rescue dogs will get all the attention in the world at Christmas, but the shelter animals will be treated no diffrently. Maybe a treat or two, but do some comparing.
I think a shelter would be best, but go where your heart leads you. I know how much you love Goldens, and I know you'd like to donate there, so do whatever you feel is right. I'm just offering my opinion.

Again, I admire you. You are so very kind.
