I love rescue dogs!
These two guys are our current rescues (my mom's, actually, but I'm their trainer/auxillary cuddler)
Shadow (the BorderJack) came from the WPA Humane Society. She is so sweet, silly, fuzzy and cute.
Then there's Buddy. Poor Buddy was found wondering in rural Ohio, and was turned into the Columbiana County Dog Warden. He was also scheduled for the "long walk on a short leash", if you catch my drift, until we dopted him site unseen from Petfinder. He looked like this when he came to us, although what you can't see is the skunk stink radiating off of him:
And who knew that there was a beautiful, adorable fuzzy purebred Jack Russel underneath that:
He is on his way to being a Canine Good Citizen as well!
Ideas for your daughter:
1) Organize a dog/people walk to raise money for a local shelter.
2) Train dogs for CGC/Therapy Dog International
3) See if she can work with the local humane society/SPCA on doing "animal education" seminars with the younger scouts. Meaning she (possibly accompanied by a rep from the shelter?) would talk to younger scouts about how to properly care for an animal, why it is important to walk a dog, what to do if you see an animal being mistreated?
4) Related to the above, see if she can design and write/illustrate a book/pamphlet on animal care/animal rescue for a shelter?
