    SmartBreathe® Pellets is rated 4.5 out of 5 by 439.
    Rated 4 out of 5 by from Just stated 1month ago and our 22 year old Welsh pony seems to be breathing with more ease while working. His warmup cough is hardly noticeable. He was coughing so much at warmup he break to a walk. This product will be but to its best test in the heat of the hot humid summer. I think it will help.

    Rated 5 out of 5 by from AMAZING Effect - Quick acting and life changing My 12 y/o gelding started showing signs of COPD last year, mostly seasonal-related. Temperature changes were his biggest trigger; dust did not seem to be an issue. Was very manageable, until he tore his suspensory ligament in February and had to be stalled 24/7 for several months. His heaves became so bad, he would go down on his front legs in coughing fits. Constant discharge and strenuous breathing. Tried changing sawdust around; 100% pine large flakes helped, but symptoms remained. Once healed up enough from the ligament injury, he went out on pasture board to alleviate. Helped some, but was still struggling. Vet had us on a cycle of Dex & Pred; started discussing expensive inhalers for his bad attacks. Then I found SmartBreathe. Almost IMMEDIATE turn-around; no labored breathing, NO coughing, and zero nasal discharge. Within weeks, he was back to the same perfectly healthy horse from several years ago. He gobbles up the supplements, even if fed alone, too, which helps a ton.Cannot say enough good things about this supplement. An absolute MUST for any horse showing signs of heaves, asthma, COPD, etc.

    Rated 5 out of 5 by from Chronic cough seems to be better I started a horse on this supplement after receiving an email detailing respiratory benefits. This is a horse who has had a cough for a good part of his life that occurred with work and in his stall. He has been scoped and nothing was found. He has been on antibiotics for long periods of time but the cough continued. He has been on the supplement for about 6 weeks and I am told that there is significant improvement. He is not coughing with work. Still has occasional coughing jag in his stall but not like before. His hay and shavings get sprinkled with water. The barn manager/trainer has said to definitely continue this supplement as if has made a difference.

    Rated 5 out of 5 by from Cough free It's bad when your horse has as many alergies as you do. If it was dry or hay roll got damp,poor Jazz would cough, eyes water, and nose run. It was a constant vet call, shots, and eye wash. Read about this and tried it. Within a week, he was better. At the end of a month, no signs at all. He has no problem with the pellets, in fact, he thinks they are treats.

    Rated 3 out of 5 by from Does not like the pellets My horse does not like the pellets. If I remember right, you used to have a powder form. She used to eat that easily. She seems to have a problem with too many pellets in her feed bowl at once. I have been experimenting, though it sounds weird it is true. This supplement has made her leary of what I put in her feed now. She hates the taste of this one the most. I would much rather use the tubes.

    Rated 5 out of 5 by from It works great! I bought this to try it out to help my older horse. He has some seasonal allergies and usually has a cough at the end of the summer from the dust outside in the turnouts. All year round he might cough once or twice when warming up then is fine. Since being on this supplement his cough has stopped! I rarely see or hear him cough anymore. He is a very picky eater and I have a hard time eating supplements. He gobbles up his smartpak no problem! I'm very happy with this product! Two thumbs up!! Thank you SmartPak!

    Rated 4 out of 5 by from just starting with this supplement my horse has terrible allergies. I started this about a month ago. She has been also taking medication to help with breathing so it is hard to say how helpful this supplement is. She is able now, with the weather change here, to take a break from the medication so maybe the supplements are helping.

    Rated 5 out of 5 by from Saved my friend's horse's life My friend's 28 year old horse was continuously coughing very hard. Steroids from the Vet made him founder. His future was not looking good. Then he started taking SmartBreathe and was cough free within 3 days! He has been on SmartBreathe for over a year now and continues to do great. He will remain on SmartBreathe for the rest of his life. Thank you for making such a great product!

    Rated 4 out of 5 by from Horse loves it. My mare has no problem eating it. I add it to daily feed. She is a rescue so I don't know all that she has been through but, she has not coughed since we finished the first bucket. I know it is helping build her up.

    Rated 5 out of 5 by from Works Well I have been using this for over a year. My gelding is extremely sensitive to dust and mildew. Since we started using Smart Breathe he has not had an episode where he is unable to breathe due to swelling of his nasal passages and severe congestion.

    Rated 4 out of 5 by from smartbreath pellets--horse loves them! I bought this product trying to help my 21 y.o.gelding . He coughs like a heavy smoker but since he is on the pellets he coughs less and seems to be more comfortable. The meds from the vet did nothing. I will continue to feed this.

    Rated 5 out of 5 by from Really works I have been using this supplement for 2 years now on my TWH who was having an on going cough- seen by vet SMZ 14 days some improvement. Read about smart breathe and started using it- very little coughing first year almost none second year. I pay attention to dusty hay etc. but I truly believe this daily supplement helped to improve the quality of life for my then 4 year old mare!

    Rated 5 out of 5 by from SmartBreathe Pellets help my horse cough less. My horse used to blow her nose and cough during our morning rides, now she still blows her nose a little, but the coughing has gotten much better. She actually coughed so hard when cantering that she lost her lead before we started feeding SmartBreathe.

    Rated 5 out of 5 by from Really worked for my horse My 20 year old mare had coughing issues in the summer on and off for a couple of years. The vet said she was starting to have allergies. Then last summer she had the cough with a runny nose and kept both all winter. Had the vet check her out again and still thought allergies. So I got the SmartBreathe Pellets this March after reading all of the reviews from other SmartPak customers. She has been on this for 6 months. It took a few weeks, but she has not coughed this summer and the runny nose is gone too! I add the pellets to her morning grain and she didn't even noticed a difference. She is a good eater so I wasn't surprised. I am so pleased with this product!

    Rated 5 out of 5 by from Really works! My three horses have breathing issues due to bad hay when they were younger. Now just a hint of mold or dust and they start wheezing and heaving. I have tried everything from prescriptions from the vet to soaking their hay. The soaking worked but it took a long time for the wheezing and heaving to subside. I got the small bag at first to see if it worked and by one week I noticed the heaving subsiding. By three weeks their nostrils weren't flared and by two months they were barely coughing and all other symptoms were virtually gone. I love Smart Breathe pellets. I only wish I'd discovered them sooner so my horses didn't have to suffer for so long. And they LIKE IT! Thank you Smartpak!

    Rated 4 out of 5 by from Seems to work I bought this for my horse who is on stall rest and in a dusty barn all day. he was starting to sneeze, snort, and show symptoms of headshaking. I put him on this and noticed a very subtle difference over time, but I definitely do think it's working. he has been on it for 2 months now and has improved immensely.

    Rated 5 out of 5 by from Does it work? Are these reviews all hype? Yes it does! Not hype at all! Very much worth the money! If your horse coughs and 'cough free' doesn't quite do the trick, if cough is persistent even when not at work, USE SMARTBREATHE! My filly had a cough that scared me so bad, I thought I had blown out her lungs and she would be done for.. 2 weeks on this and I haven't heard or had reports of her coughing in over a week!! So relieved.. I had used cough free before it had gotten this bad and had little effect.. I am sticking with SmartBreathe.. And the taste? I feed pellets and she eats them without hesitation (they even have a funny scent that I had been worried about)..
