I'm so glad to read the replys you've had so far! :)
Yes you can do both & as Tohme said, you can do lots of other things too.
If you've got the time to spend with your dog, you can teach him to do whatever you like. So many people say you can't do both & it is rubbish!
I too have successfully done both with different breeds of dogs.
Put the work in now & you'll benefit so much.
Good luck & enjoy your training. :)
