The exact origins of Hurricane Dog are obscure, due to sparse ship and land observations over the eastern Atlantic Ocean; the storm may have originated from an easterly wave on August 24 near the Cape Verde islands, but there are no observations to support such development.
Ships first encountered the storm on August 30, when the SS Sibrodin reported gale-force winds and an area of low pressure about 320 miles (510 km) east-southeast of Antigua.
The storm is first documented as a hurricane with winds of 90 mph (145 km/h) late on August 30.
With high pressures to its northeast, the storm tracked west-northwestward and rapidly intensified: on August 31 it attained major hurricane status, reaching winds of 130 mph (209 km/h)—the first peak intensity in its life—before entering the Leeward Islands.
Early on September 1, Hurricane Dog passed just north of Antigua as the equivalent of a Category 4 hurricane on the Saffir-Simpson hurricane wind scale.
A weather station on Antigua reported a pressure of 28.73 inches of mercury (973 mb), though the eye of the hurricane missed the station.
After bypassing Antigua, Hurricane Dog weakened slightly, based on reports by reconnaissance aircraft; the cyclone made its first and only landfall over Anguilla with winds of 120 to 125 mph (193 to 201 km/h).
The cyclone produced hurricane-force winds over Antigua and the nearby island of Saint Martin, which reported a pressure of 978.7 mb (28.90 inHg).

Early on September 2, Hurricane Dog came under weak steering currents, causing it to drift northward.
The cyclone weakened even further: aircraft recorded a central pressure of 962 mb (28.4 inHg), and maximum sustained winds diminished to 115 mph (185 km/h).
The storm mostly maintained its intensity for two more days, but on September 4 it began to re-intensify as it turned northwestward.
On September 5 Hurricane Dog regained Category 4 intensity about 335 miles (540 km) north of the eastern tip of the Dominican Republic.
The hurricane strengthened further after turning to the north, and Hurricane Dog reached its second and strongest peak intensity of 145 mph (233 km/h).
On September 6 Hurricane Hunters visually estimated peak winds of 185 mph (300 km/h) about 450 miles (720 km) south-southwest of Bermuda; however, being early in the period of hurricane reconnaissance, such wind speeds—derived from observations of the sea surface—were subjective and sometimes unreliable.
In 2014, a reanalysis of HURDAT by the Hurricane Research Division found that the peak winds in Hurricane Dog were more likely 145 mph (230 km/h), marking a reduction in the intensity of Hurricane Dog from Category 5 to Category 4.
Nevertheless, while now estimated to have been less intense than assessed operationally in 1950, Dog was a formidable hurricane while over the western Atlantic, producing wave heights of over 100 feet (30 m).

Hurricane Dog maintained its peak intensity for about 12 hours.
On September 7, the cyclone attained a central pressure of 948 mbar (27.99 inHg), which was the lowest pressure in association with the hurricane.
A building ridge of high pressure to its north caused it to decelerate and weaken steadily for unknown reasons as it turned to the west; by September 9, the intensity had decreased to 75 mph (121 km/h).
On September 10, Hurricane Dog began turning to the northwest, and a day later it headed north and then northeast.
Late that day, it briefly re-intensified slightly to 100 mph (161 km/h) before transitioning into an extratropical cyclone with hurricane-force winds.
The former hurricane passed within 200 miles (320 km) of Cape Cod on September 12.
Shortly afterwards, the extratropical remnant turned to the east, losing hurricane winds for several days beginning on September 13.
The system eventually turned to the northeast on September 15, and a day later it regained hurricane-force winds as a vigorous extratropical cyclone.
Early on September 17, the cyclone struck Scotland with winds of 75 mph (121 km/h), but the system persisted until finally losing its identity north of Scotland on Septe
