Lifesaver?
I wrote a long review for a nebulizer chamber we bought this to use in. My mom instead points it at her cat’s face when he’s asleep and she wears a mask and lets him inhale it. Vets (two different) told my mom her cat would be dead in hours or a day from fluid around his lungs. They said the test to drain & examine the fluid would almost certainly kill him & cost almost $2,000. She told them he still had quality of life. He was playing with his toys and eating well and watching the birds. He slept on her lap and in bed with her all night. Sunbathing etc. She refused to euthanize him AMA and took him home to die. We bought this solution and got an old vet to prescribe antibiotics. It’s been a month and a half since all that and he’s still alive and holding his own. We credit this solution in part. It’s worth the money. It’s a big bottle so it’ll last you a while. We are grateful to other reviewers who convinced us it was worth a shot.

This device is worth every dollar spent.
My sweet 10lb Shipomepoo was suffering from bronchitis and seasonal allergies, and seemed to feel better after spending some time in a steamy bathroom. I was happy that the steam was helpful, but didn’t really want to waste all of that water every time she seemed overly congested so I was happy to find this product. It took a few brief sessions for her to get used to it, but once she did, she put up very little resistance, and it worked wonders I highly recommended if your dog is asthmatic, has allergies, or is prone to chest congestion. As an asthmatic myself, I can vouch for the relief a Nebulizer can bring, and I’m so grateful there was one available for my little Jazz.. It’s easy to use, small, and quiet. Just be sure to start with short 1-2 minute sessions to give your pet time to acclimate to it. Give it a try. Your pet will thank you. By the way, it comes with not only animal but human masks, so it should be great for traveling and children as well.

Magic!
Wow just wow! I have a 10lb Yorkie that caught a respiratory infection from my other pup that daughter when she got spayed. Only he got it worse. He was wheezing on and off for several days, he couldn’t get excited without sneezing or wheezing bad (still ate, drank, etc.) … I told myself I’d give this a shot before I took him to the vet. To our surprise, it worked. We only did 2 treatments of this for about 7 mins each time. He’s been running, playing, etc. without wheezing. Highly recommend!

Seems to work for my cat, but I’m super allergic to this!
PetSilver’s “Immune Support, Natural Nebulizer Solution, Promotes Respiratory Health in Cats & Dogs, Allergies, Sinus & Cough Treatment, Easy to Use, Patented Chelated Silver, Made in The USA, 16 fl oz,” seems to be okay for minimizing respiratory symptoms that my super senior cat is currently having, unfortunately. Hope he feels better soon… 🙏🙏 It’s easy to use, super calming and doesn’t smell. That said however, I’m very allergic to this. The back of my hands were itching, oozing, flaking, bleeding, and drying out so badly and they’re going up into my arms resulting from exposure of the steam coming from the nebulizer as I was giving it to my cat. It is also causing me to want to itch my arms so badly and when I do, it opens up small lesions and are bleeding. The reaction is also kind of delayed. At first, I was feeling the back of my hands tightening up and feels like they’re retaining water, and hard to form a fist, and then, it developed into red patches, super dry, flaky, with some areas bleeding and oozing. My throat and my nose are also another issue resulting perhaps from inhaling some of the ingredients while nebulizing my cat with this. It has been days now, since my allergic reaction to this first showed up, and I’m still dealing with it. Prescription steroid ointment, Benadryl topical cream, Benadryl liquid-gel, and Corn Huskers Lotion seems to be helping little by little. Fortunately, I know that these will eventually heal with time… That said, be cautious about this product since while this works well for others but, this is NOT for everyone! Hope this review helps… ♥️

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.

I cannot return the item, but i read so many reviews about this and do not buy it. I regret spending this, after doing research, i decided that it was not a great idea to use.
