Northern Greyhound Rescue (local to me, based in Lancashire UK) has just taken in over 30 greyhounds from a racing kennel due to significant welfare issues. They’re a small charity and this amount of dogs is a massive strain on them. The dogs need kenneling, food and veterinary care, some have injuries which need treating. They would be grateful for any help at the moment.
You can donate through their web page and apply to foster or rehome one of these beauties there too. Visit their webstore and buy yourself something nice - all profits go to the rescue. You can read more on their facebook page as well. If you can spare anything i know they would be grateful. I just applied to foster or adopt one of these beauties :)
