There is an easier way, two as far as I can see.

You can split the string up based on

i) the positioning of the .
ii) the consistent locations of the numbers.

So for the simplest case of ii) you could

compress dob
gen str2 dob_day = substr(dob,1,2)
gen str2 dob_month = substr(dob,3,2)
gen str2 dob_year = substr(dob,5,2)
destring dob_*, replace
gen dob1 = mdy(dob_day,dob_month,dob_year)
format dob1 %d
