DNA profiles are something which will be really important to the breed itself soon, but mainly to UK, where we have several people breeding mixes and people finding it normal. Also it's not hard neither expensive to do.
I agree with the DM test, but you shouldn't take it too serious when we talk about selection as even the veterinary which did the tests recommend people to treat it as one common standard fault.
I really worry about some people reaction to the DM test results, it's great to try to select only free dogs, but it really shouldn't be put in first place. Also the gene SOD1, which is tested at DM test is easy to get rid of at the breeding, different of hips and principally of elbows displasy, for exemple.
