And all of that can be done with a mixed breed dog just as well as with a purebred dog, except for the kinds of titles that are restricted to purebred dogs (and even then, breeding titled dogs of different pure breeds would produce a mixed breed dog with titled parents)....breeding a doodle is not responsible breeding! There’s a lot that goes into proper breeding, health testing, genetic testing, lineage/pedigree tracking, titles, finding a sire and so much more.
So I do not see how you decide that ALL breeding of doodles is irresponsible.
I do agree that learning and researching are a very good idea.There are tons of online resources as well as books and first hand experiences about ethical and responsible breeding
