    SmartBreathe® Pellets is rated 4.5 out of 5 by 500.
    Rated 5 out of 5 by from Works wonders Daily feeding of this product has all but eliminated any abnormal respiratory sounds from my husbands heel horse.

    Rated 5 out of 5 by from Works Product worked as described. My horses ate it without any problem. Cough subsided in a few weeks. Love it when products actually do what they claim.

    Rated 4 out of 5 by from Cough disappeared I ordered SmartBreathe Pellets since my mare came up with a persistent cough. Although it wasn't terribly bad, she would cough a few times a day and always when we started out trotting. After only one month I can report that the cough has disappeared. My mare can be picky when it comes to supplements, but she devoured this without any issues.

    Rated 1 out of 5 by from MSM made my horse anxious, nervous, spooky I bought this product for my horse who has a very mild COPD. She coughs a couple times in trot during our warm up. I received this around march 15th 2017 and the following weekend I took her to a horse show fro the weekend where she was a nervous and spooky mess and started refusing fences. I was perplexed and chalked it up to maybe her first estrus cycle. The behavior continued at home and I had eyes checked, chiro done and also scoped for ulcers. She had grade one ulcers and we have been treating in hopes the nervous spooky behavior would go away. A month later I still had a very nervous and spooky horse who is usually very level headed and will jump through fire. I stumbled upon a couple of COTH message board threads that mentioned that MSM made their horse nervous and anxious and spooky. I took my horse off this the next day and within 3 days I had my horse back. I also did not notice a noticeable difference in her coughing.

    Rated 5 out of 5 by from No spring Heaves! Since moving to Colorado 3 years ago, my mare Na'vi would get horrible heaving coughs every spring when the weeds start to grow. This spring I started her on the SmartBreath and no heaves! This is invariable to me because I need her in best condition for compete in sortings and competitions. I told my veterinarian and has since recommended it to clients horses that would normally be on steroids for heaves and now don't need steroids and are breathing clear.

    Rated 5 out of 5 by from My Sugar has heaves. This allergy season has been difficult with all the oak pollen and lack of rain. I noticed less of a heave line within 2 weeks. Though she's not 100% she's 100% better than she was before the smart breathe pellets. My Sugar thanks you!!

    Rated 5 out of 5 by from Bad cough My boy had a horrible cough. This has changed that and he breathes so much better! It took a couple months, however I am so happy with it and excited about the results it had on Cisco! I would highly recommend trying this. It is also great since Cisco is such a picky eater, he ate this wonderfully.

    Rated 4 out of 5 by from Life saver My son's pony has COPD. We have used several drugs and breathing treatments to get her through the worst of it. Now I use SmartBreathe. It's convenient and easy to feed. Right now she is 110% better but allergy season is coming so that will be the real test! So far we love it. She has been on it for two months. Only downfall, it is rough on their stomached so now I ad Aloe Vera juice to her feed every time I feed her. I wish it was easier on her tummy! But overall an awesome product so far!

    Rated 5 out of 5 by from My Mare Is A New Horse I've been using smart breathe for over 3 years now for my mare. She has a break in her trachea from a previous injury that makes her breathing heightened after minimal work. With SmartBreathe her breathing is much more fluid without that raspy inhale and coughing exhale. I had to take her off it for a few months and her breathing was significantly worse. Now she is back on it and feeling great! Dusty arenas and working bother her no more!

    Rated 5 out of 5 by from Love Love Love SmartBreathe!! I am on my second month of SmarkPak for my horses and I wish I would have started feeding SmartPak from the beginning. My gelding is 16 years old and has seasonal allergies and heaves. After being recommended this product by a friend, I decided to try it and I honestly wish I would have started my horse on SmartBreathe years ago. Within the first couple weeks, I noticed his coughing and breathing was improving. One month into feeding SmartBreathe and he's is a completely different horse. Noticeably more comfortable. Coughing has been reduced to very very rarely if ever. I am very pleased with everything SmartPak has to offer for my horses.

    Rated 5 out of 5 by from Marked improvement in breathing My young miniature mare has had breathing issues for several years now and has been examined by three different veterinarians. She does not have heaves, but evidently has inflammation in her nasal passages without lung involvement. No one has been able to make much difference in her condition without resorting to steroid use. With less than two months of using this product, she has shown at least 85% improvement in ease of breathing. SmartBreathe pellets have been wonderful for her health.

    Rated 5 out of 5 by from Really helps my mare My mare has seasonal allergies and breathing issues, and SmartBreathe really helps her out. I give it to her during the spring and fall and it really eases her symptoms. She likes the taste of the pellets and I have to admit I love how they smell. Her seasonal cough has resolved since I started using SmartBreathe.

    Rated 5 out of 5 by from SmartBreathe Pellets SmartBreathe Pellets were recommended by my vet. I am always skeptical about how valuable supplements are but I have seen my horse's breathing issues improve since using this product.

    Rated 5 out of 5 by from A definite must-have for horse with heaves! One of our rescue horses suffers from heaves and between this & smartimmune he no longer has to have steroids multiple times a day! In fact, since being on smartbreathe & smartimmune he has gone from 2x/day steroids to help him breathe to 2x/YEAR!! He's a semi-picky eater but has no problem gobbling up these pelleted supplements!

    Rated 4 out of 5 by from Picky eater likes SmartBreathe My gelding has allergies to the point that his vet suspected heaves. I had him on Cough Free for about 6 months and his lungs got better, but the nasal discharge and coughing continued. My gelding didn't like to eat his supplement. Now that he is switched to SmartBreathe for a month, his cough is almost all gone and there is no more nasty nasal discharge. And my gelding likes to eat his grain with SmartBreathe pellets.

    Rated 1 out of 5 by from Buyer Beware - Do not use in horses with ulcers! I started my horse on SmartBreathe about 4 months ago. He had developed allergies following a move to a new stall where there was hay storage above him. We moved him back to his old stall and started him on SmartBreathe. He was better within a week. However, he began having chronic GI issues. After 3 courses of UlcerGard and Sucralfate, many vet bills later and a still-symptomatic horse, I stumbled upon the paperwork that came with his first month's worth of SmartBreathe and was horrified to read that SmartBreathe may be a GI irritant and should not be used in horses with ulcers (see attached pic.) I immediately went to the SmartPak website to see if it was mentioned there since I didn't remember reading anything about GI irritation. I would never have started him on SmartBreathe had I known since he had had ulcers in the past. Sure enough, there was absolutely nothing on the website. Shame on you SmartPak! That "Cautions" statement should be clearly displayed on the website so other horse owners can make a better decision than I did and so that other horses don't end up in a viscous cycle with ulcers and GI issues. In the past when my horse had ulcers, 1 course of Ulcergard did the trick. Not so this time. Ugh! Can't help but wonder how many horses are on SmartBreathe and SmartGut...

    Rated 5 out of 5 by from My mare is no longer coughing! My 25 year old QH mare was recently diagnosed with heaves, and had a respiratory infection on top of that; which made for a very nasty, lingering cough and difficulty breathing. After completing the recommended treatment from the vet, I started her on SmartBreathe pellets. It's been about 2 months and there has been no more coughing, and she is breathing much better. The farm she is boarded at even feeds round bales (as they feed several other horses, cows, and a herd of goats), and still no issues. I'm so happy that she is no longer coughing and I plan to keep her on SmartBreathe for as long as I have her.

    Rated 5 out of 5 by from Great product!!! This is month two of my Mae being on Smartbreathe and I am so happy I tried it I have my horse back!! I've tried several products both prescribed by my veterinarian and friends to no avail. This product is amazing. My mare has no coughing wheezing or heaving or trouble breathing anymore. I plan on taking her back into the show ring which two months ago would've been unheard up thank you so much for everything you've done for her.

    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.

    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.
