I just noticed one of our Silkies gasping for breath, I guess "gaping." I suspect gape worm, but have heard it is kind of rare. We've never dealt with it before. We tried the Q-tip test, but didn't see any worms. Then again, she wasn't cooperating very well. Opinions? What treatment should we use? Any input would greatly be appreciated! Here's the link in case it doesn't work right.
