General Rules:
* Purebred Registries: If you are registering with a purebred dog registry (like the American Kennel Club or UK Kennel Club), both parents must be registered with the same registry and be considered purebred (meaning they have both parents registered as the breed). This is because these registries focus on maintaining breed standards.
* Mixed Breed Registries: There are registries specifically for mixed breed dogs (like the American Canine Association or the International Canine Registry). These registries often allow you to register a litter if only the dam (mother) is registered.
Your Situation:
Since the sire is not a purebred Shih Tzu, he likely cannot be registered with a purebred registry. However, there are a few options:
* Register with a Mixed Breed Registry: You can register the litter with a mixed breed registry. This will be the easiest option.
* Register with a Purebred Registry (Limited Registration): In some cases, purebred registries may offer a "limited registration" for litters where one parent is not fully registered. This registration may restrict the offspring from being shown or bred.
Important Note: Before registering, it's crucial to:
* Contact the Specific Registry: Always check the specific rules and regulations of the registry you are considering. They will have the most up-to-date information.
* Understand the Consequences: Make sure you understand the implications of registering with a mixed breed registry or limited registration. This may affect the dog's future in terms of breeding, showing, or selling.
It's always a good idea to speak with a reputable breeder or a veterinarian who can advise you on the best course of action.
