The RSPCA hasn't 'pulled out' of Crufts, just suspended plans.
The RSPCA has suspended plans for stands at Crufts next March and Discover Dogs this November.
I honestly don't understand the objections to any of the following recommendations being implemented. .

Possible ways forward
The RSPCA has commissioned an independent review of the science in this field, and will be discussing its findings with relevant experts and stakeholders later this year.

Amongst a raft of specific recommendations, the following themes have been identified as possible ways forward.

# An overhaul of the rules and requirements for pedigree dog registration and competitive dog showing (including breed standards). Health, welfare and temperament should be prioritised over appearance.


# The development and implementation of health and welfare-focused breeding strategies for individual breeds. This should include pro-active steps to increase the genetic diversity of dog breeds.


# More data collection and scientific analysis on causes of disease and death in dogs.


# Education, especially of would-be owners, to encourage demand for dogs which have the best possible chance of leading healthy, happy lives as pets.
It might be as well to go and read what it is all about 'from the horses mouth' so to speak. Note the word 'save', no-one is out to destroy any breeds, in fact, having seen the BBC documentary, I would suggest the recommendations are the best way forward to avoid the awful suffering of some.
