I have been giving my 10 year old 5 pound chihuahua ground farm fresh eggshells for 2 months and she has had one episode since we started treatment. I use a Krups coffee grinder and get them down to almost powder fine. This is a huge improvement all with no chemical intervention! Yeah!! I would only use farm eggs that you can be sure momma chicks have been free of antibiotic treatment.

you can also use organic eggs.

I give my 3 pound Pom one 1/4 or

1cc syringe I'd Robitussin DM it dries the mucus trapped in her c trachea. Also I use a humidifier with 5-6 drops of eucalyptus in it.

Also to calm her down from the anxiety of not breathing. I crushed calm forte in water table spoon. I give it to her by syringe. It works so wonderfully altogether.

my Pom has a severe case of collapsed trachea. I took her to the vet. She is on theophylline a bronchial med. It does help her. The robitussin really helps her cough 1/4 teas. I also use 3 drops calendula non alcohol organic and 3 drops astragalus non alcohol organic extract. I am also trying the organic eggshells It is very important to not gain weight.

I spend 24/7 with my chihuahua and know instantly when something is up. I could tell after he gulped down a treat a little too big that there were remnants stuck in his throat and had all the collapsed trachea symptoms. He had a little but now it was really bad. Anyway they told me olive oil is a good way to soften hard bits of food so I started putting a few teaspoons in his wet food and seriously his 'honking'/snoring is 70% better. Whatever was stuck is now not and it was there for 2 weeks. He never snored before either. Maybe your pom has some food stuck. There's a post on google about eucalpytus oil and showers too that apparently helps.
