Ugh.
Shoot me, I skim read but still..
registered breeder and licenced breeder ... these terms may not mean 'reputable, honest, producing quality, healthy animals', but unfortunately people think they do.
There is no such thing as a registered breeder - there are people producing Kennel Club Registered puppies and there are Assured Breeders of Kennel Club Registered puppies (ie, the KC has checked them, they must meet a higher criteria in housing, and breeding).
Licenced breeders are commercial enterprises - you require a licence if you produce what the goverment/local authority deems to be sufficient to be considered a business.
Breeding domestic dogs as a financially viable business is ONLY possible if you cut corners somewhere.
Some licenced breeders are simply considered commercial because of the numbers they have, and are not making a profit and are doing a good job, but many more are, and are cutting corners to do so.
we aren't bothered about bloodlines or Crufts... you don't need to be, but theres no GOOD reason for anyone to be producing pedigree dogs that are not, or cannot, be registered or produce registered offspring. Only bad reasons (ie, bitch too young, bitch produced too many, bitch not actually registered herself may not even be pedigree...)
whilst I am at it...
vet checked in reference to the puppies, ie a vet has cast an eye over them at some point before you take yours home, is NOT the same as health tested parents, ie the parents have been tested for known genetic conditions and these results are available for you to see.
It sounds like the OP has bought from a puppy farmer or puppy importer - both are bad but the latter is worse as theres a much greater risk of your puppy bringing rabies into your home, as these are imported without the rabies jab or before it can be given or are given it too young before it can actually work.
