Can? Or should?

Probably shouldn't, but it happens. When it does, the offspring should be outcrossed for several generations.

Means that they are bred to dogs with the desired similar traits that are not related to their linebred portion of the pedigree.

What you are desribing is called a 2-3 or 3-2 line breeding. It is a strong method to influence type and lock in traits. The coefficient of relationship is 37.5% and the coefficient of relationship is about 9.63%.  This is an newphew to aunt mating or an uncle to niece mating.

This is called "Bracket's Formula". Let the sire of the sire be the grand-sire of the dam. This is a strong line breeding but it is not inbreeding (which is half siblings). https://dpca.org/breeded/bracketts-formula/
