    SmartBreathe® Pellets is rated 4.5 out of 5 by 440.
    Rated 5 out of 5 by from Respiratory issues and allergies Second month that Jack is on this supplement and I see improvement. His cough has almost stopped.

    Rated 5 out of 5 by from Works! My paint gelding starting coughing. A lot. He never coughs during exercise. We thought it was allergies, but had him checked by the vet who suggested environment changes first - hay fed only on the ground, wet hay, etc. She said if that doesn't help, SmartPak makes a great supplement. Winter came and he was still coughing, so I talked to a SmartPak rep and we started him on SmartBreathe. After three weeks, there was a significant reduction in coughing. We are at week five now and the excessive coughing is gone, even though it is spring now!

    Rated 5 out of 5 by from Helped my horse tremendously A neglected TWH came to me 5 months ago. One of his problems included COPD which showed as coughing, wheezing, and breathing difficulties. We had the vet out and paid hundreds of dollars during one attack. She recommended trying Omega Fatty Acids and I also saw that SmartPak had a respiratory supplement. I give it every day and the horse has not needed vet attention since. He coughs only on rare occasions and does well on trail rides. I'm impressed!

    Rated 3 out of 5 by from I think it worked! My gelding developed an upper respiratory cough so I thought in order to assist his recovery, I thought I would try some SmartBreathe Pellets for him. The cough resolved itself with the help of antibiotics, eucalyptus essential oils and Smartbreathe. He has remained cough free and I have discontinued all of the products now. He was only on the SmartBreathe for about 30 days so I do not know if they helped or not, but he is fine now without the Smartbreathe pellets or oils. As far as the palatability goes, as you can see I have a very chubby, haffie cross who eats anything....and he didn't really love the flavor of the smartbreathe. He does get a handful of grain in the mornings so I had to mix the smartbreathe pellets to his grain. He would not eat it on its own.

    Rated 3 out of 5 by from Did not work for my gelding Sadly this did not help my gelding with his coughing/seasonal heaves. I thought it was at first, but I saw his cough slowly getting worse as we went into the spring pollen season, which is awful this year in Ga.

    Rated 5 out of 5 by from Worked great for my mare! My mare had a cough for a few days, so I bought a supplement at a feed store, and had her on it for a week and half. Nothing changed. Not sure why she had the cough, could've been hay, could've been allergies, who knows. She wasn't sick though. So I decided to add smartbreathe to her smartpaks, and after just a few days on it. She was coughing less. And at the end of the 28 days, no cough at all. Thanks smartpak!

    Rated 5 out of 5 by from This really works! My 14 year old gelding has trouble breathing when fed round bales at his boarding facility. After using SmartBreathe Pellets for about a month, he sounded much better. Now, after about 6 weeks, I don't notice any heavy breathing at all. I'm amazed and very happy!

    Rated 4 out of 5 by from Helps with heaves Bought this to try as a long-term supplement for my horse, diagnosed with heaves in December '15. We finished a course of steroid and antihistamine, and started him on SmartBreathe. So far, his coughing is rare, and hopefully we'll avoid more medications this year! If this supplement does the trick, I'd give it 5 stars, but it's only been a month.

    Rated 4 out of 5 by from It Works! I bought this for my horse cause she was weazing and coughing. We will soon be going on month 3. I know the weather has been crazy here for the winter but I thought I would give it a try. It Works! She isn't weazing and hardly coughs at all now.

    Rated 5 out of 5 by from Worked when nothing else did My gelding developed allergies and a horrid cough. I had tried albuterol and some other things recommended by the vet, wet his feed and hay, and nothing helped. I was ready to quit riding him, since his cough so often interrupted our rides that neither of us was comfortable. Called Smartpak as a last resort, and SmartBreathe pellets were recommended. After a month or so of doing the dosage wrong, we got it right, and after a few weeks the cough was nearly gone. He is now back in work and very comfortable, with minor coughing. I am so glad this product was recommended. And so is Bentley.

    Rated 5 out of 5 by from Game changer! Very noticeable difference My 18 year old mare has been suffering from coughing episodes for a couple of years, and I finally decided to put her on SmartBreathe about 9 months ago after having minimal luck with other supplements. One of my main issues when trying to give her supplements is that she is a very picky eater, and although she turns up her nose when she smells it in her bucket, she usually does eventually break down and eat it.This product works great for her. I was actually concerned at one point that we wouldn't be able to ride regularly or compete anymore because she coughed so much. She does still cough sometimes, but it is not the guttural hacking that she used to do, and it usually occurs if she doesn't finish her supplements.

    Rated 5 out of 5 by from This saved my horse's life We were planning to have my horse euthanized due to chronic heaves. We started her on Smart Breathe Pellets and, after a month, she is not struggling to breathe, her nostrils are not flaring and we are not going to euthanize.

    Rated 4 out of 5 by from Works Wonders. great product Dakota has mild heaves and SmartBreathe Pellets work wonders. She is breathing better and the coughing is under control. The smell of the pallets seem to bug her a bit, she doesn't want to eat them alone. we have to mix with honey but they work great.

    Rated 5 out of 5 by from Sonny actually ate these, no mixing needed Sonny will not take meds. I have to use a syringe to give meds. He has seasonal allergies. I always give Sonny a treat after we ride. I placed the first dose in his bucket. He ate all of it and licked the bucket! He is not coughing.

    Rated 5 out of 5 by from Seems to work! My horse was recently diagnosed with COPD. We've been wetting the hay, and he's outside permanently, but just when he would seem to get better he'd relapse! He's been on smartbreathe for two months now, and I have noticed significant improvement! I can't say for sure if it's the smart breathe, the weather, or both (it's now winter in Chicago), but the improvement is drastic enough that I will definitely continue with this smart pak!
