There's also a note on their thread on dp for help with wormers etc.
"Because Many Tears Rescue takes many ex puppy farm dogs, our vet bills are extensive! Please, if you go to your vet, buy a packet of Stronghold, Frontline, or some Drontal Plus Wormer for these poor dogs, as they come in so needing to be wormed and de-fleaed, which is all very expensive!! (This treatment will help make them regain their health and feel well and happy quicker)."
or e-mail on sw.vanatta@virgin.net
Many Tears Animal Rescue can be found at

[Note I believe you can get some of these things cheaper than the vets if you buy online; can't remember where though]
