    SmartBreathe® Pellets is rated 4.5 out of 5 by 449.
    Rated 5 out of 5 by from Great My vet suggested I try this product as my horse has seasonal allergies. This prevented him from having to get an inhaler and paying for the vet to come out every time he had a flare up. I no longer have to worry about him not being able to breathe due to him having coughing fits. He's been on Smartbreathe for 3 months and rarely coughs, even when it is dry for weeks and the dust, mold, and pollen count is very high!

    Rated 4 out of 5 by from My mare has respiratory issues in the spring and summer due to allergies. I had her on Anahist H which was working fine but on the expensive side and only available in a very small container, so I decided to try this one during a sale. So far it seems to be working just as well. She still has had mild issues on and off but nothing that has prevented her from being comfortable being ridden so far. In the beginning she refused to eat it (she can be picky with new supplements) so I literally just mixed 1/4 of a well in with her grain and soaked it and added a little molasses and gradually worked up to the full two wells. Now she eats it just fine without being soaked or adding any molasses.

    Rated 5 out of 5 by from excellent product When my horse started having trouble breathing I was afraid he was going to bed on harsh meds for long term and cause other health issues. Once he was over the initial inflammation I've been able to keep him comfortable with this product. One call to you people has made my life easier and my horse happier..

    Rated 5 out of 5 by from Great Product! I started my horse on this for general respiratory health as well as to ease a dry lingering cough she had when I rode her. After only a month and a half of SmartBreathe, she already coughs less and her breathing sounds better after a hard workout. She even likes the taste of the pellets!

    Rated 5 out of 5 by from The only thing that has worked! I've had my Paint horse since he was a yearling, and around two years old he developed seasonal allergies. I tried antihistamines which worked for about the first season or so. Tried going the vet approach, which involved a lot of steroids and money...it worked but who can afford $30 a week for the ventapulmin when it got bad, along with other meds. Then I found a supplement that worked OK, but it smelled awful and tasted just as bad. Once he started straining his food in his water bucket, I about gave up. He was to the point you could barely ride him as he was coughing so much...not to mention that when he ate, he also ate, which made me worry about him inhaling his food and causing further problems. Then I called SmartPak and decided to give this product a try. I figured I'd give it the couple months of worry free guarantee and hope for the best. It worked like a charm and this will be my second season using this product. I seriously couldn't be happier with this stuff. It has saved me a boatload of money and restored my horse's health.

    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.
    Date published: 2016-02-18
    Rated 4 out of 5 by from She eats it right up. She seems to breathe better and has energy again. Good product. Easy to feed and she likes it.
