Emeraldgreen - by all means, check out whatever you can find at health food stores and other local places.

But DO ask your vet if there are any nose drops or anything you can put in the vaporizer. I like the vaporizer idea because you said his lungs are "gargly", so if he can inhale safely medicated steam, that should help.

Also - try printing out all the vet medical stuff I found and faxing it over to your vet. I am NOT trying to play vet here, or doubt your vet at all - but you could ask which of those methods might be good.

It's written in your vet's language - "Vettinese".

HUGS!
