Line bred traits and dominant traits are not really related...
Dominate traits would still be controlled by a single allele, and are very similar to recessive traits. The kicker is that while a recessive trait has to have two copies of the recessive to express the trait, a dominant trait only has to have one copy.
A line bred trait is controlled by multiple alleles, that is why there is such great variation in line bred offspring.
Here is a breakdown:
XX = wildtype
Xx (recessive trait) = het, does not show the trait
Xx (dominant trait) = het, shows the trait
xx (recessive trait) = shows trait
xx (dominant trait) = shows trait, can even be fatal in some instances
I'm sure Jeff can add to this.
