If you are looking to register your dog with one of the officially recognized canine associations then you will need the right paper work and registration papers for filing. Your veterinarian Columbia, MD may be able to help you determine what paperwork is necessary and where to obtain it. In general, if your dog is a dog then he is eligible for the American Kennel Club association registration as long as his litter has been registered. If you purchase a dog under the assumption that it is a purebred dog then you should have received an individual dog registration application from the seller. You will need to complete the application and submit it to the AKC along with fees and any other requirements as outlined on the AKC website. Dogs can also be registered online. You should receive a registration certificate from the AKC in about three weeks.
