There are so many ways you can help - ranging from actively as a foster home to more passively as somebody with Doberman knowledge and experience can be called upon for advice. Maybe you can offer to foster for a simple two week period - this will allow a full time foster parent a break, maybe to take a vacation?
Money makes the world go round - and rescue groups certainly need money
to help fund their programs.
Currently the DPCA Rescue Committee has a very limited supply of
merchandise - which it sells at the Nationals in October. However -
check you local rescue group's website - maybe they have a shop and have
just what you are looking for.
Home visits; Transport; Evaluations; Write for their newsletter; Take photos for their webpage; Whatever your expertise, or whatever you are willing to offer, a rescue group will welcome your offer of help. You don't have to go to the shelter; you don't have to take a strange dog into your home; There are many other ways that you can ease to load on the group - many ways that you can help a Doberman find a new home.
