Dog spike is a spike with head square or round top, bottom fro square wedge nail. It is usually used in wooden structure railway fastening system. Track spike, also named railroad spike or dog spike, is used to fasten T-shaped railroad track to wooden railroad ties. It has an L-shaped head and a square shank. The bottom of its head is sloped to match the slope of the flange of a rail. Its tip is wedge-shaped, not pointed. The wedge is driven into the tie across the grain, that is, parallel to the track.

Why is it called dog spike by people, too?
Maybe its L-shaped head is the resemblance to a dog's head. A dog spike is functionally equivalent to a railroad spike and is also square in horizontal section and of similar dimensions but has a pointed penetrating head, and the rail (or "plate holding") head has two lugs on either side (which aid spike removal) giving the impression of a dog's head. The main function of the spike is to keep the rail in gauge.
The specifications of common track spikes are the 5/8"*6" and the 9/16"*5-1/2" for smaller rail sections, and they are usually packaged in either 200 lb. kegs or 50 lb. kegs.
