There are dog rescue groups that specialize in particular breeds; for example, there are malamute rescue groups, German shepherd rescue groups, etc. There are also dog rescue groups that are not dedicated to rescuing any particular breed. These all-breed rescue groups rescue any dog that is being aborted by his owner, and they also rescue dogs from overcrowded animal shelters.
Dogs that are rescued, for whatever reason, are taken to dog rescue centers, where they are first calmed down by caring staff members, fed, and given fresh, clean water. Once the dog has been calmed and is feeling better, the dog is bathed, and any minor cuts and scrapes that the dog might have been treated. The dog is also examined for internal and external parasites (worms and fleas) and correct medications and treatments are started.
During the entire process of the dog being cleaned, examined, and treated, dog rescue volunteers are constantly talking to the dog, petting the dog and providing comfort to the dog. Once the dog is deemed healthy, he then moves on to foster care.
For many dogs, the dog rescue center is the first place where they have ever had a decent meal or ever been petted. The care that the dogs receive is very likely the first act of kindness that they have ever witnessed, much less had directed at them.
The foster families that take rescued dogs are carefully screened. Foster families are very special people. They are accredited to taking in unwanted and abused animals and socializing them. Before rescue dogs are put up for adoption, they are trained and know how to be part of a human family.
Dog rescue groups provide a much-needed service. Most all of them get the funds needed to rescue and care for abused and thrown-away dogs from donations made by people who care about the welfare of dogs.
