 Try /cow, then :/s/cow/dog followed by nnnn& 
 '&' repeats the previous substitution.

 Actually in this case, you can also try
  /cow [return] cwdog[escape]nnnn.  

 The first version has the advantage that it remembers only the 
 exact latest substitution done through 'ex' (i.e. in the command mode), 
 whereas the '.' command remembers any non-ex change like deleting
 a line, etc.  I am sure somebody will correct me if I am wrong.
