Rescuing did cross my mind, though it was pretty much impossible given that I have a cat and also the fact that there are so few Huskies in my area, the few that are in rescues get snapped up quickly.
We have had two dogs that were re-homes though the main reason for that was because these people were family and both dogs were very much loved.
I'm not going to lie, I am turned off shelters because most are dogs I would never consider in terms of breed.
I think I would only re-home a friend or family members dog like I have in the past. Someone who I know well and someone who I have seen truly love their dog and not want to let them go.
That's just my opinion and I will say there are many great dogs in shelters though there was only one that I fell in love with and if I could have taken her in I would.
We will never see an end to the overpopulation without stricter laws preventing it.
