The Dog Lovers Registration Club was set up by the proprietor of a large scale retail pet outlet. No reputable breeder would sell ttheir puppies to a third party.
The dog Lovers registration club registers any dog with whatever information the breeder wishes to provide, which may or may not be true. It is used mainly by puppy farmers or others who cannot register their puppies with the Kennel club. Reasons for this may be that the parents are not registered, or the mother has had too may litters or is to young. Possibly the breeders are so lacking in knowledge in canine matters that they weren't aware of the Kennel club.
This registry does not run any shows or trials, does not run health screening schemes.
In most peoples eyes the papers you have are not worth the paper they are written on, and point to the fact that your pup is not responsibly bred.
I do hope she turns out well for you, but you certainly shouldn't consider breeding from her, as you have no way of tracing her ancestry to check for temeperament, health, and conformity to the breed standard, and of course any pups she had could not be registered with the Kennel club or shown (except at Exemption shows where any dog can be shown for fun).
