If they are written only on paper?

If the standards can be legally be changed, then the answer is easy, re-write the standards.

What to change? Want my opinion?

Get the breeders themselves to reach that moment of realization where they understand that they have been breeding for harmful mutations.

Those breeders who can't understand will have to adjust to "We are all doing it this way now, breed accordingly."

What to change in the standards is very easy - maybe if you are too close to it, you can't see it, but just breed normal looking dogs.

Some basics:
1. Dogs have a tail. The tail expresses the dogs emotions.

2. The dog's tail should NOT curl over it's back. A curl in any part of the spine, could mean a deformity in other parts of the spine, which might not be obvious when the dog tries to stand normally.

In dog sign language, a tail temporally curled over the back is a sign for aggression or suspicious alertness - which is not generally the baseline temperament you want your dog to have.

A genetically curled tail, that usually stays in that position, communicates this mental state all the time - leaving owners and guests unaware of when the dog is hyped, because he always looks like that.

3. Dogs have two ears. Dogs with one ear, might have had a damaged ear, dogs with two cropped or chomped off ears should not be shown, because how would you know what type of ear he genetically has? And if you let people show cropped dogs - some people will crop their dogs ears.

Dogs ears come in various forms. Some dog's ears are like a wolf's ears - they usually stand up, but are mobile. Some dogs have ears that flop down. Some dogs have ears that part way stand up. These are all okay.

But some dogs are bred to have very long ears. This does NOT help them hear better, it's like having giant ear lobes (although it is actually the whole exterior part of the ear).

Very long ears are bad, especially if they are wrinkly. The dogs can get ear infections, and the tips of the ears can drag the ground when the dog puts his nose to the ground.

3. Dogs should not have very short legs. Dogs should not have very long backs.

4. All dogs should have teeth that meet well. The incisors should meet in a scissor position. Level or slightly undershot is a fault. Obviously undershot or overshot is a DQ.

5. Dogs like to see, they should be allowed to do so. All dogs whose hair covers their eyes, should be shown with their hair pulled away from their eyes, or with their bangs cut. (This one is easy to do, it is not a breeding change.)

6. Dog's hair has a natural growth direction. Dogs with cowlicks or ridges of hair that grow the wrong way, should not be shown.

7. Dogs have a snout, a muzzle. If a dog doesn't have a snout, he can't breathe right. Dogs without a snout (flat-faced dogs) should only be bred to dogs who do have a snout. Dogs without a normal snout should not be shown.

8. Dog's skin should be elastic, but not wrinkled or in folds.

9. Dogs should have eyes that are set like a wolf's eyes, or somewhat deeper or a little bit shallower set. Dogs should not be shown if they have pop eyes.

10. Dogs have four toes and one dew claw on each front leg. Each back leg should have 4 toes, with one dewclaw being optional.

There are probably lots of others, if I took the time to think on it, but you get the idea, of what I mean.

And what about all the health problems that can't be seen? Aren't they even worse?
Yes, they are. But we have to start somewhere, and this is something the breeders can see without testing. Judges can see it.
