Since you are only looking for two specific words, just use two variables,  $lazy and  $dog. If you might later want to know how many times any other word (say "jumps") shows up, then use a hash. . .

This smells strongly of homework btw. . .

Update: Sorry, I mis-read your original post. Since what you are looking for is the offset between the two words in every sentence, why not just use an array? I don't really recommend using a hash where the keys are sequencial numbers.
