Linebreeding / Inbreeding / Tight Breeding or whatever you choose to call it NEVER CAUSES such things as pink noses, bobbed tails, rear dew claws or anything like that.  BUT...by breeding tight you are essentially narrowing the gene pool which will result in recessive traits (already present in the dogs) becoming more common in the phenotype of the progeny.

You can cull for a specific trait and over time have that particular trait evident in all offspring, however that does not change the fact that the trait is either dominant or recessive.
