Question: What do Serbian Hound and St. John's water dog have in common?

<P0-S0> The Serbian Tricolour Hound ("srpski trobojni gonič" or "trobojac") is a breed of dog of the hound type. <P0-S1>  Formerly called the Yugoslavian Tricolour Hound, the name was changed for clarity after the breakup of SFR Yugoslavia in 1991. <P0-S2>  The breed was first exhibited at shows in 1950. <P0-S3>  At one time it was considered a variation of the Serbian Hound, but was recognised by the Fédération Cynologique Internationale as a separate breed in 1961. <SEP> <P1-S0>  It is red or tan with a black saddle, neck and cranium and red or tan face. <P1-S1>  Its head is flat and sloping, its muzzle pointed, with drop ears of the usual scent hound type. <P1-S2>  The Serbian Hound stands 17 to 21 inches (44–56 cm) in height and weighs about 44 pounds (20 kg). <P1-S3> The Serbian Hound (Serbian: Српски гонич / "Srpski gonič" ), previously known as the Balkan Hound (Балкански гонич / "Balkanski gonič"), is a pack hunting dog breed used in Serbia. <P1-S4>  It is smooth-coated and coarse-haired. <P1-S5>  Described as pleasant natured and obedient, the breed is thought to descend from dogs left in the Balkan region by the Phoenicians in ancient times. <SEP> <P2-S0>  Little is known of the types that went into its genetic makeup, although it was probably a random-bred mix of old English, Irish and Portuguese working dogs. <P2-S1> The St. John's water dog, also known as the St. John’s dog or the lesser Newfoundland, was a landrace (a dog bred for a purpose, not pedigree or appearance) of domestic dog from Newfoundland. <P2-S2>  The number of St. John's water dogs started declining by the start of the 20th century. <P2-S3>  By the early 1980s, the variety was extinct. <SEP> <P3-S0>  Within the three islands in the United States Virgin Islands, St. John has maintained a higher percentage of dry forest cover competing with St. Thomas at 43.1%; St. Croix has limited dry forest cover (9.22%). <P3-S1>  The characteristics and development of Virgin Islands Dry Forest are contributed by a unique wind pattern that is usually strong. <P3-S2>  Dry forests lack an abundance of moisture, yet, there is an adequate amount of moisture to sustain the growth of the forest. <P3-S3>  High quantities of sea salt from the ocean decreases the height of the trees. <P3-S4>  Dry forest also consisted of layers of canopies, specifically two canopy layers that commonly found at an elevation below 300 meters. <P3-S5>  The island contains 650 native plants, 5,000 or more terrestrial insects, over 180 species of birds, of which 90% are native, and six native mammal bat species. <P3-S6>  St. John and St. Thomas topography has significant steep hills and slopes compared to St. Croix. <P3-S7>  Dry forest receives 850-1100mm of precipitation per year. <P3-S8> A Dry Forest are defined as a community of trees of different species that coexist in the same environment. <P3-S9>  One of the most common trees in the “native dry forest garden” is the amarat. <P3-S10>  St. John is the most protected of the three islands, and as such it has the largest extensive tropical dry forests in the U.S. Virgin Islands. <P3-S11>  Although dry forest tends to grow at an intermediate height compared to moist forest. <P3-S12>  These trees can grow nearby forming a canopy above. <P3-S13>  There is limited dead dry wood for termites to consume, this correlates with low density of termites in dry forests. <P3-S14>  They are acacias, (casha bush) but do not have thorns likes most other varieties.
