In the 1899 show, with 311 entries of cattle, and the age limited to three years, no beast reached the weight of a ton, the heaviest animal being a crossbred(Aberdeen-Angus and Shorthorn)which,at three years old, turned the scale at 19 cwt.
In this case the first sire was a white Pomeranian, the second a crossbred Irish terrier.
On the other hand, from the experiments of Mendel and others, we now know that crossbred animals and plants may present all the characters of one of their pure-bred parents, and we also know that the offspring of what are regarded as pure-bred parents sometimes revert to remote, it may be quite different, ancestors.
In both cases, these are for systems with crossbred ewes bred to terminal sire rams i.e. with all lambs intended for slaughter.
Outside of a breeder's carefully controlled environment, the PWD has often been crossbred with Poodles.
