Stopped the hacking almost immediately
My dog has allergies and has been coughing a lot. The vet was thinking it was acid reflux, but I knew that wasn’t it given his history, especially since when we visit my parents down south he doesn’t have the coughing fits. So I bought this to try and a little hand-held nebulizer. My dog doesn’t like using the nebulizer for too long so I’ve been doing it for 20-30 seconds at a time. He hasn’t coughed since his 2nd treatment and it’s only been one day. I’m super excited for him that I found something to stop his coughing. He has been doing it about 2 or 3 times an hour, especially at night. We’ll see how he does tonight. Update 02/20/2026: My baby is sleeping so much better. He's not waking up coughing and hacking all the time. His fits have drastically reduced, but are not entirely gone. I am going to start a combination of nebulizing (for about 20 seconds since that's all he tolerates) and also putting it in his food. Hopefully, that will help reduce his fits even further.

Natural Nebulizer Solution for Pets
I can’t explain how good this product is. My pet had a sinus infection and I was giving him treatment with the nebulizer. His allergies got better with a conjunction of a natural antibiotic that I gave him. Easy to use, very effective and the value I paid was worth any penny. Also the size of the bottle is pretty big and durable.

That it helped my dog breathe, but it didn’t
I I should’ve read the whole ingredients and it turned out that this was not good for my dog that it would cause more problems in helping it

It really works!
I bought this for my 8 year old female Weimaraner who developed trigeminal neuritis this past year. Because of her condition, she has a perpetually stuffy nose that frequently gets clogged and results in sinus infections and general misery. I thought this product would be minimal help at best, but it’s absolutely amazing how much better she feels after just a handful of treatments. Don’t get me wrong - she hates it. She hates the nebulizer and the moist air, but it helps her so much. Her sinuses are clear and she can breathe!!
