From the same one mating the puppies looked pretty much alike. The colour may be a surprise, because you're getting genetic material from earlier generations which may show up. Example: a black American cocker spaniel dam mated with a white min. poodle sire threw one black female, which became silver when mature, and the rest of the litter were female and coloured like the sire, though one was markedly golden in tint.Explanation? The sire's sire was silver,I learned.Silver puppies start out as black. The golden colour of one may be because that one parent had apricot in its bloodline somewhere. All the puppies were more like the poodle in coat than the dam and didn't moult like the dam did but the coat was more silky than a poodle coat, more like the dam's.In type, they had the exceptional agility and the light frame of the poodle but the face was quite spaniel-like, Note that some breeders don't breed colour to colour in poodles and they get a mixture of colours in litters as a result.That's their market to the public,who may want a choice of colour ( I disapprove!).
They may not been any guarantee that the next identical mating will produce pups like the first litter, but I'm no geneticist !
Breeding the same crossbreed to the same crossbreed, and so on down, could produce almost anything! 'Labradoodles', so-termed, themselves seem to differ quite a bit, notably in the degree of moult in the coat . These may be labradoodles bred to labradoodles, of course.To breed a recognisable breed, like the Dobermann, requires very selective breeding indeed, to create animals that breed true to type.
