Thanks for the response, Mike.
I do have access to an acoustic-electric and will give that one a try. Adding an equalizer is a great suggestion. I never even thought about independently changing out the low E string with a thinner one. I'll try that too. I suspect that these changes will remedy the problem, although I'll undoubtedly still need to contend with the howling. You're right, there probably isn't a more fitting song to accommodate the input of one guitarist and two hounds. I'll try to shoot and post a video of our cacophony once I've mastered the song.
