I am so proud to have the same name as someone as good hearted as you. Please do not give up looking for a way to help. Maybe there are some rescue organizations in your area whose requirements aren't as strict. These groups often foster dogs in the volunteers homes. Maybe if you lived near one of the foster homes you could stop by to help groom or exercise the dog or dogs they foster. I think that would be a big help. I mention this because I saw a group of foster dogs at PetsMart this weekend and several of them looked like they needed a good comb out.
