removing unwanted sounds with Audacity

[espman2]

Hi,
I've posted before about a problem I have. I have some dog barking while I was doing a show at an SPCA. I woyuld really like to remove most or all of it. Problem being, some of it happens while I'm talking, some doesn't. A response was posted to try to use Audacity to correct it. For the life of me, I just can't seem to do it. I've watched all the tutorials on youtube. None of them deal with that sort of problem.
Is there anything out there, free or otherwise, that might isolate the frequency or wave length and eliminate it that way?
Thanks,
espman2
