I sincerely hope so.

Some of these will be worse for it. And the majority of breeders and buyers don't consider the health of the mix, they only care about looks.

Think about the spazzy disaster that is the Labradoodle

No, it is not an improvement. The breeders are despicable, cruel, greedy, evil "breed".

Not really. If someone is promoting . Lets say it's dangerous, like all the people trying to breed. It is serious.

2/2 it can be reversed if there's enough of the original stock left) But you always have to take into account that other things come together with the new desired trait. Like in the German Shepherd, they tried to outbreed the problem with the hips (in Germany), but there were other health-issues that came to light. The hips are better now... they have different problems now (like heart-problems, problems with the elbows and so on - though I'm sure they were there before, too) If you only ever breed one breed with a different one, you can create very nice-lookiing dogs, but once you breed with the offsprings, things get lost again. So many "Breeds" like the labradoodle are not a breed because they just take Labrador + Poodle and that's it. It's a mix. Just costs more.

Sometimes, it can actually be, true. But just randomly picking one dog and putting them together with another from a different breed is not "breeding". That's just "producing puppies". If you wanted to better the breed, you'd need full health-checks and also a good look into the parents and grandparents. How old did they get, what issues did they have - stuff like that. Then, if you wanted to actually change the breed long-term, you'd have to make sure the things you want to change stay inheritable. If you want longer noses or less wrinkles for example, you'd need to make sure that the offsprings can also breed to that trait. And of course you can't just do it one time, you'd need more dog-couples to make a stable, large gene-pool so the new breed won't one day be completely related to each other. It's a S**T ton of work to make a new breed, and it's a bit easier to breed for a body-type (it's easy to create atrocities like the pug and the very-wrinkly Shar Pei, and it can be 1/2

Absolutely not. No pedigrees no way to monitor health of parents. You dont know much about dog breeding if that's as ill you know.
