Michael, This is a little bit off your topic but you said you were thinking of getting rid of your dogs and on that I have a little experience. I have CF and I own a dog kennel / daycare. I am around lots and lots of dogs every single day. I have had Pseudomonas in the past but with antibiotics it has gone away. I use TOBI now every other month and my cultures have been negative. I don't have any sinus problems and even being around all the dander and fur does not bother my lungs. Now ask me to take my dog for a walk to the corner and its a whole different story and god forbid if someone comes with me and wants me to talk while I walk. That I can't do. All I'm saying is don't rush to change everything in your life all at once because of what might happen. There are lots of people, adults and children who live with pets and are fine. Good luck!
