Gallees and Gallahs are humanoids, having heads, tail and fur of Earth-type dogs, and sometimes sporting keen senses of smell and hearing. (Color-blindness is also very common amongst Gallees and Gallahs.) They can be found in a number of places on Sinai, but particularly in the Nordikan country of Gallis, and in the sky island of Rephidim.
The distinction between Gallee and Gallah is that Gallees are "pure-breds", corresponding to a number of Earth type dog breeds, most notable being the poodle. (Poodles have a tendency to hold high status amongst the Gallees.) Gallahs, on the other hand, are "mutts" -- either by virtue of having mixed parentage, or unfortunate mutations that make them less than the ideal of their given breed.
Insofar as physical abilities, the average Gallee or Gallah is comparable to a human, and is also similar in size. However, the occasional Gallee or Gallah -- more often the latter -- may sport heightened senses of smell and hearing, and just about every Gallee or Gallah can hear a dog whistle. Contrary to real-life dogs, most Gallees and Gallahs have no trouble digesting chocolate (or xocholatl); however, that isn't to say that there isn't the occasional "genetic throwback" that might have trouble with it. (This isn't enough of a difficulty to warrant a Disadvantage, though.)
If there is a "homeland" for Gallees and Gallahs, it would be the country of Gallis, in Nordika. While Gallis does not officially support slavery, it does have indentured servitude, and a very rigid caste system that makes sure that the pure-breds have plenty of mutts to support their leisurely lifestyles. (Visitors to Gallis who are slave-owners won't be hassled, though they'll get along better in polite society if their slaves are referred to as "servants". It's quite possible to have a Savanite slave in Gallis, but if the slave runs away, it would be one's own responsibility for reclaiming the lost "servant" -- not to impose upon the local authorities to do so.)
In Gallis, while not all Gallees are nobles, even the middle-class Gallees have fairly high standards of living compared to the average surface-based society. The same, however, cannot necessarily be said for Gallahs (mutts) in Gallis.
The country of Gallis has its own language, Gallisian. Gallees or Gallahs in Rephidim might know the language, but they're far more likely to just use Rephidim Standard.
It should be noted that most Gallees are likely to be influenced by Gallisian culture or family ties to the same. There is a very strong cultural imperative that Gallees only marry within their own "breed". To do otherwise would produce mutts (Gallahs) and would call into question one's own "purebred" status in society. If this were not the case, then intermarriage would soon guarantee that the distinct "breeds" of Gallees (poodles, German shepherds, Dobermans, collies, salukis, etc.) would cease to exist after a few generations.
PC Requirements: There are no PC requirements, per se, as the average Gallee or Gallah differs very little from a human in basic abilities. However, one point in Sense of Hearing and another in Sense of Smell would be easily justified.
