Checking health claims

Well...Florie Bell Pups claim to have great reputation with both the council and & RSPCA. You could contact council to inform them about them as I should imagine this breeder is registered one as well as to RSPCA and see what they have to say. And as they also claim to comply with all the breeding regulations and standard of practice, it should be in a interest for both of them.
You could also find out what is the star rating for this breeder with local authority,
See; Dog breeding regulations - England | The British Association for Shooting and Conservation.

 

I am actually suprised that a licensed breeder. ..breeds cross bred pups ......
Sorry about your experience better to know ...now than have a whole lot of heart ache ...
I hope you find a healthy pup soon ...

 

I've heard some pretty poor reports of Florie Bell. They breed some really weird crosses, it is a commercial puppy farm.

And being registered with the council means they breed a certain number of litters a year.

Puppy Farming

 

Another licensed puppy farm!
Health checks by a vet just means the animal is healthy at that time when the vet saw them, it doesn’t substitute DNA testing and health schemes that looks into wether these dogs are likely to produce pups with certain health conditions or be affected by them themselves.
DNA screening schemes and results
I would check out any dam and sires health test results on mykc before considering visiting a litter, even crossbreeds, both parents should still be tested.
