SmartBreathe® Ultra Pellets is rated 4.0 out of 5 by 73.
Rated 2 out of 5 by from no difference noted I have been using this now on my mare now for 5 months. to be honest...I have seen no difference. It is expensive, so i figured i would give it at least several months to make my decision. my mare is recovering from tie back surgery and tends to get a little bit of seasonal inflamation per my vet. so we decided to give this a try. for the $250 i spent over 5 months i wish i would have went on the perscription ani-hisamine/ resp health through my vet. my mare ate it fine, she is not a picky eater AT ALL.

Rated 2 out of 5 by from My horse won’t eat it I can’t say how helpful this is as my horse won’t eat it. She actively avoids it in her grain. I tried for 2 months but she’s still refusing it. Switching back to the normal smartbreathe as she seems to eat that okay.

Rated 5 out of 5 by from I saw results right away. Coughing stopped. Happy for my horse. He's comfortable now.

Rated 4 out of 5 by from Just didn’t work for her My mare gets seasonal allergies. In the summer and sometimes spring she will get a cough my vet did give me a prescripted anti histamine powder that does help but sometimes they are out of that and have to wait till they get more in or sometimes she is fussy about eating that stuff so isn’t a fan of powders no matter what you mix it with in her grain, so I tried looking for other things for when I don’t have anything and came across this and had to try it! She is a very picky eater and she ate this with no problems I had her on it for two months with her cough and I noticed she slightly was maybe coughing a little less but still had that horrible allergy cough I ended up taking her off this because it is pricey and just getting her back on her prescription anti histamine and got her eating that and her cough seems a lot better. Maybe for the early spring I could try seeing if this would work for her I will update than but for starting in mid summer when her allergy was at it’s worse it didn’t work unfortunately

Rated 5 out of 5 by from Help my old man I waited to do my review until I had used for two months. During the winter months when the grass is not green, my 34 yr old appaloosa would develop a runny nose and the cough that he has year round gets worse. Since using this product, he has very little nasal discharge and I just realized this morning, I hardly ever hear him cough. If I dont mix well into his feed (soaked beet pulp, grain and alfalfa cubes) he will not eat it but mixed in we have no problems.

Rated 1 out of 5 by from Will Not Eat! I have two quarter horses that have never turned their noses up to any feed or supplement, until I tried this. Neither of them would eat their grain or beet pulp with this mixed in. It has a very strong smell and large serving size. What a bummer.

Rated 5 out of 5 by from Love the features A friend of mine suggested this product. Seems to have been helping my girl with her breathing.
Date published: 2019-11-13
Rated 5 out of 5 by from Really helps! One of the geldings I care for has always had a pretty bad cough, he had pneumonia when he was a yearling and has never gotten rid it. Ontop of this, he has bad allergies so the cough worsens in the spring. The owner has tried multiple supplements but nothing has helped him ever. I did some research for him and suggested that he added this to his horse's SmartPak, since I've always seen great results from SmartPak's supplements with my own horses. He's been on this for about 4 months and it has done wonders for him. The horse still coughs a little bit if he rides in the dusty arena, but it's nowhere near as bad as it is without this supplement. It has an extremely pungent odor, so I was worried about him not eating it at first but he never leaves any of it behind.

Rated 5 out of 5 by from Great Product I got this supplement for 2 of my horses that developed a cough this fall from seasonal allergies. It has worked great for them.

Rated 5 out of 5 by from Great Ingredients My horse has asthma related to seasonal allergies. About 3 weeks after starting him on smart breathe , his cough is almost totally gone. I highly reccomend this product!
Date published: 2019-10-26
Rated 5 out of 5 by from Can’t recommend enough! I started using Smart Breathe last summer. We used WAY less meds for heaves over the last fall/winter/spring. Recently switched to Breathe Ultra due to a big flare up late summer. Could not be happier. This supplement, plus soaking hay, and Smart Pak Spirulina, I believe has allowed us to come off of meds completely at this time.

Rated 5 out of 5 by from They work great! My broodmare has breathing and swallowing issues caused by a botched throat surgery. Any inflammation aggravates her condition. SmartBreathe Ultra Pellets have made an enormous difference in her ability to breathe well, swallow properly and be active without coughing! She has been fussy about eating other supplements but, cleans up her SmartBreathe Pellets every day. We are beyond thrilled to see her happy and comfortable! Thank you SmartPak!

Rated 1 out of 5 by from Won’t eat! Even though so many other reviews stated that their horse(s) wouldn’t eat this, I thought our horse would be different and would gobble it up! NOPE! Not only did she refuse to eat her food with this pellet mixed in, but also her pasture mates turned up there noses at their own food even though theirs didn’t contain it. So I have no idea if it works or not because our horse with breathing issues didn’t take any. Do not recommend.

Rated 5 out of 5 by from Great Product I bought this 2 months ago and it has really helped my boy breathe better. He gets allergy flare ups every year and this is the only product that gets them under control.

Rated 4 out of 5 by from Seems to be working! We are into our second month of feeding a supplement designed to help one of our horses who has been diagnosed with asthma. He still has labored breathing but seems now to be gaining some of his weight back?

Rated 1 out of 5 by from Started this a month ago and have not seen any change in my mare... still coughing
Date published: 2018-11-13
Rated 3 out of 5 by from Horse refuses to eat it Started my mini who suffers from seasonal heaves on SmartBreathe about 3 months ago. During the last month I noticed my pony stopped eating it as well as she should, and honestly it didn't make as much of a difference when she was eating it. I contacted customer service and they recommended the SmartBreath Ultra. She ate it for about a week, and now she won't touch it. The only way I can get her to eat is if I mix crushed up peppermints with it (which obviously isn't healthy to do every day for a mini horse!). Unfortunately I will probably cancel my next shipment and try to find something else. I can't say if the supplement actually works or not since she won't regularly eat it.

Rated 5 out of 5 by from Did the trick! I purchased this for my horse after he recuperated from a respiratory infection. He had a persistent cough. This product helped a lot and he is back in full training.

Rated 5 out of 5 by from The most comprehensive respiratory support! My mare has struggled with seasonal respiratory issues for years, and I previously had her on SmartBreathe Pellets. When this new formula came out, I knew it would be perfect to give her an even higher level of support. Along with her prescription medication and a management program from her veterinarian, this supplement is really helping her to breathe easy, even during the more challenging summer months. I love the addition of spirulina and turmeric, plus the pelleted formula ensures she finishes it all (and she is a very picky eater!). This product has everything you could want for respiratory health all-in-one, so you don’t have to feed multiple supplements to get key ingredients like MSM, herbs, and antioxidants. SmartBreathe Ultra Pellets have been a great addition to my mare’s program, and she is doing fantastic since starting on this formula!

Rated 1 out of 5 by from Sounded like the answer to my horse with heaves Gave as directed for over a month with no relief, back to the vet for a prescription, customer service was very accommodating, overall satisfied with SmartPak just not product

Rated 5 out of 5 by from Will definitely use agathem n! My horse was having seasonal allergies for the first time, I tried another product that smelled terrible and he refused to eat it. I switched to the Smart Breathe ultra and he loved it. I noticed he worked better and was no longer making the loud breathing noise while being conditioned. There was also no more cough at the beginning of a work out.

Rated 1 out of 5 by from Horse refused to eat it My horse ate this day 1...following day wouldn’t touch his feed and has been off his feed for several days afterwards even with nothing added Horse also got a nose bleed the next day after the one and only time he ate this supplement

Rated 2 out of 5 by from Wish this worked better My horse has no problem eating SmartBreathe, but it has not helped with any of her allergy symptoms.
Date published: 2018-03-20
Rated 5 out of 5 by from Trying This Out To See What Happens This Spring I have a very young horse who had some Airway Inflammatory issues. We treated him with steroids and he got better, but I don't want to have to do that again if it's at all possible to avoid. So, knowing I've had great results with other SmartPak Products, I started him on SmartBreathe Ultra Pellets. So far, he likes them, eats them no problems and we've had no more coughing or wheezing. When spring arrives and the allergens are really in full force, I'll update and say how he's doing.
Date published: 2018-02-20
Rated 4 out of 5 by from Seems to help! This is our 2nd month using smart breath ultra. our older gelding has a chronic cough with occasional mucus, this supplement decreases the frequency he is treated by our vet with prescription medication.
