The Sniffer Hounds are dog-type creatures that have long, prehensile tentacles that they use to drain the blood of their prey. They have dirty, leathery skin which appears to be decaying and, strangely, make snarling sounds which resemble that of a large feline rather than a canine. Since they are blind, they use the large eye on their legs to see. The male variety has visible eyes, ears and green tinted fur and flesh. Females are missing eyes and ears and are purple tinted, with longer, sharper claws. The gender and rank of the Sniffer Dog is betrayed by their coloration. Green-tinged Sniffer Dogs, thought of as males, are weaker and less threatening than the purple-tinged, thought of as female, variety.
