The pugdog is a dwarf race, probably of mastiff origin, and kept solely as a pet.
Apart, but standards in orchards should be allowed at least 30 ft., and dwarf bush trees half that distance.
Its flat-roofed Moorish houses are enclosed by gardens of cactus, dwarf palm, orange and other subtropical plants, interspersed with masses of rock.
Young plants a few inches high are usually attacked; the leaves, beginning with the lower ones, turn yellow, and afterwards become brown and drop. The plants remain very dwarf and generally unhealthy, or die.
Grasses, mosses and Arctic flowering plants are abundant, but there are no trees excepting occasional dwarf willows.
