Repair or replace deck beams?

[NathanW]

We have a staffy pup that has decided to chew one corner of our deck support beam. There is not a hell of a lot of damage but it is noticeable and WILL be noticed by out landlord.

Im after some tips and tricks that i can use to repair the damage in the attached photos. After all is said and done, the one option sure to fix it is to replace the entire beam, and that's not entirely out of the question.

Any helpfull pointers on how i might go about repairing this would be extremly helpfull.
