Dog engagement is normally used in racing applications where fast, precise
shifting is needed. Dog gear engagement is facilitated by numerous large
teeth (dogs) that mate into matching openings machined into the opposite
surface of the drive gear. Unlike the synchro engagement, there is no
synchronizing mechanism to assist in equalizing speed. Ideal gear
selection—e.g. minimal clashing and wear of the dog rings—is achieved
by quick shifts; the motto here is "the quicker the better", so bang away.
There is no depressing the clutch in the conventional sense like with the
synchromesh transmission. A momentary break in engine load until the shift
is achieved by a quick throttle blip or clutch depression. The driver will
then experience the dog ring engaging with the next gear and the throttle
can be reapplied. With practice this can be done in milliseconds. In fact,
a driver can preload the stick shift in the direction of the next shift,
and then when he either blips the throttle or clutch the shifter will
quickly click in the desired gear.
With all else equal, dog-engagement gears are much stronger than
synchro-engagement gears because without needing to make space for synchro
rings, the gears themselves can be made thicker. The number of dogs (teeth)
and the size of the openings determine the window of opportunity that the
dogs have to engage during the shift event. Rings with a smaller number of
teeth provide a more efficient, smoother shift quality. The downsides to
this easier engagement are increased noise and abruptness on the shift.

Ariel Atom V8 vs 600bhp rallycross Citroen DS3 vs BMW HP4 superbike drag race - autocar.co.uk
Which is faster? An Ariel Atom V8
track day toy, BMW HP4 superbike or a rallycross Citroen DS3 with 600bhp?

a straight line. Time for a drag race then. So what are the contenders?
There's the one-wheel drive BMW HP4 superbike, which arguably requires the
most skill to extract speed from but has a ludicrous 757bhp/tonne
power-to-weight ratio. Then there's the two-wheel drive Ariel Atom V8 with
748bhp/tonne and the Citroen DS3 Rallycross car with only 577bhp/tonne but
all-important four-wheel drive. Oh, and did we mention it's wet?
