Perhaps all Brachy breeds should have this added to their breed standards.
Boxers here in the UK have a decent muzzle length by and large compared to some other countries.
With this kidney issue some advise importing from abroad, but as the gene responsible and mode of inheritance isn't confirmed, you would have no idea if you might not not only be bring in dogs clear of that issue,b ut might actually also bring in some more extreme traits prevalent in other countries.
The problem with PDE all along has been there is a view that problems can be solved simply, by out-crossing and crossbreeding. All that will do is hide an issue for a time, and may actually bring in problems from the other gene pools not evident currently in the one your working with.
Also that anything could have changed in the physical make up of breeds in just 3 years, (policies and aims maybe) only a generation on, for some dogs (dogs in the ring will range from 6 months to 12 years or more).
Worst of all portraying pedigree breeders as deliberately causing problems, when in fact often it's a closing the stable door after the horse has bolted, issue.
You only know there is an issue after the event when significant numbers arise with issues, and then you are stuck with trying to fix things which is never easy, throwing baby out with the bathwater may lead to further gene-pool bottlenecks. Also using an out cross to solve a problem will mean possible overuse of that animal, so more issues of inbreeding on an individual for it;'s good traits and having to deal with it's negative ones.
Also re inbreeding levels. Until computer programs most people would only have a vague idea of inbreeding levels, by counting the number of times a name appeared in a five generation or more pedigree (many won't have full pedigrees further back than that, especially with imports), working on a percentage of blood basis (the way I looked at pedigrees).
I am pretty sure that quite soon the KC will mandate that no new litters with COI' of above 25% (what you get with first degree matings of parent to offspring and full siblings) which are already banned.
The current mate select tools will need to be developed so that matings further ahead than just existing dogs can be calculated, in other words what if I put the potential puppies of X and Y to the potential puppies of C and D together.
I already work at least another generation ahead with outline breeding plans. when planning a mating I look at potentially what will there be to mate the offspring to to best effect.
The pedigree dog is an easy target just because there are records for them so when something crops up the root can sometimes be found and some people like to witch hunt and cast blame.
The unregistered farm collie pup may be very inbred for all anyone knows, no records so who knows, it may be purebred, or have a bit of something else Lab, JRT, Springer), and it is likely that any health issues encountered are put done to one of those things, when in fact the local romeo may have been passing on negative genes to many offspring.
Crossbreeds, accidental, deliberately bred unregistered litters are likely to occur in a small area, the owners do not travel to mate their dogs, so the populations may be as inbred as any small breed.
My husbands family had working Russels, without any pedigree, when they had a litter from them they had no idea if the chosen dog from someone with a good worker was not in fact related closely to their bitch as no-one new more than who bred Mum or the dog in question.
