Star had a horrible dry cough; mainly in the mornings. The vet suggested children's cough medicine, which maybe helped a bit. It wasn't too bad at first, but then it suddenly became a lot lot worse. Really scarey. (She is inoculated against kennel cough.)
Different vet suggested getting her to inhale steam. (Tell me how!!!!)
Then someone suggested Olbas Oil. I put some on a tissue and held it in front of her nose so she had to breathe it in, for about 30 secs.
By the next day, she had improved greatly. I repeated this twice daily for two days, and it completely disappeared.
Not only has the cough gone, her breathing is quieter, and she doesn't snort and snore at night. Fantastic!
There have been a couple of slight recurrences, but at the first sign I give her a sniff, and it's gone. The last time, I wiped some under her chin, so she breathed it in, but couldn't lick it. Worked a treat.
I've recommended this to a couple of people on these boards. Maybe it'll work for you. Hope so.
Only £3:80 a bottle. Miracle cure!!
