Okay, I got a reply (and a bit of bad news) . They think 3 of the 5 pups have parvo.

She says you can donate via Paypal, sending the money to the rescuer's home or sending the money straight to the vet hospital. If you choose to send it straight to the vet, make a note that the money is for "Amanda and Shawn Charles & the rescued Pit Bull Puppies". If you (or anyone else) would like the paypal account or the rescuer's home address, I'd be happy to ask her.

She also wanted to thank you for helping.
