Number of teeth shown in the formula multiply by 2 gives the total number of teeth in dog. in typical dog dentition includes 42 permanent teeth which are shown by the dental formula as follow

i 3/3, c 1/1, pm 4/4, m 2/3 .

To simplify further it is customary to omit the initial letter so that the same formula in dog dentination and their dental formula can be written as 3.1.4.2/3.1.4.3 = 42 teeth in adult dog. It means upper jaws have 20 number of teeth and lower job have 22 number of teeth in adult dogs.
