For example, in humans X-linked traits are more common in males.

In birds, the sex chromosomes are known as W and Z. Normal males have two Z chromosomes and females have one W and one Z chromosome.) There are no X's
In bees and ants unfertilized eggs become males (haploid), while fertilized eggs become females
In the fruit fly XX gives a female and XY becomes a male, but the situation is more complicated than in mammals; it is really the ratio of X chromosomes to somatic chromosomes which determines sex. Dogs have 39 pairs of chromosomes 38 autosomes and 1 pair of sex chromosomes. I would think your answer is dogs.
