To find a breed-specific rescue group in your area go online and search your city’s name and “Border Collie rescue.” You will likely discover that there is a group close to you that specializes in helping and rehoming Collies. The Border Collie Society of America can also direct you to local rescue organizations.
The dogs at rescue organizations generally do not have anything ‘wrong’ with them. They are there often as a result of mismatched expectations on the part of the owner. If you are educated about owning a Collie, you can often find an excellent dog via a rescue group. You can expect a rescue group to have a variety of adoption requirements. They may want you to complete formal application, participate in a phone interview, agree to a vet and reference check, allow a home visit, and pay an adoption fee. Rescues will also usually ask that you return the dog if the adoption does not work out at any time.  If you are interested in competing in AKC competitions with your adopted dog, there are options available to you. It is possible to apply for a Purebred Alternative Listing (PAL) registration through the AKC website.
