LM's characterixation of this saddle-tank is "interesting", but Locobase finds it to be a fascinating example of making the most of quite restrictive requirements. (Two examples of American mine locomotives designed by Baldwin in the early 1870s (Locobases 10027-10028) have similar dimensions and power.) Engine height was limited to 6 ft (1.83 m) to pass through the Saundersfoot tunnel, which was bored in 1829.

The colliery was located at Begelly in Pembrokeshire. It was linked through the Saundersfoot Harbour and Railway Company's four-mile (6.4 km) line, which ran southeast to the port of Saundersfoot on the Bristol Channel near Tenby. Accordng to the , the Reynolton colliery opened as an anthracite drift mine in 1906, then rebuilt in 1914 by the NRAC, who bought the Bull Dog soon afterward. Fortune failed to smile, however, and the mine closed in 1921 with all but a few outbuildings cleared from the site.

The Bull Dog didn't go begging, however. It was transferred to the nearby Bonvilles Court Coal Company, where it worked until 1930 when that mine closed. It remained in a shed until 1934-1935, when it was run between Bonvilles Court and Broom Colliery until 1939. Bull Dog left the coal industry, transferring to serve the Llanelly steelworks in Llanelli, Carmathenshire, where it was regauged to standard gauge (1,435 mm). It was scrapped in 1951.
