in reply to reverse of string

It's all about context. reverse by default works on a list in this case is in list context. Since there's only one list item ("dog"), it's printed out. In the second example, ucfirst forces the reverse into scalar context and in scalar context, reverse, combines all the elements of the list and returns the string value of that combination in reverse order.

    reverse by default works on a list

    <niggle> Nope. reverse doesn't have a default behaviour. In list context it reverses a list. In scalar context it reverses a string. The print puts the reverse into a list context, hence the behaviour that confused the OP. </niggle>
