    Rated 5 out of 5 by from Amazing difference! I started this about two months ago on my irritable and spooky mare - I LOVE IT! This supplement has helped take the edge off of my mare - now she is much more focused and willing to pay attention.

    Rated 5 out of 5 by from Game changer!! I had my mare on this last year and took her off of it due to boarding her in a barn that was very expensive. I didn't realize how much the supplement was helping. She turned into being very irritable, wanting to bite at you when you were brushing her belly and cinching her up. It all came to a head when my trainer worked her for 60 days and she would have a month of good and then all of the sudden would act terrible for several days. He suggested that i put her on a very expensive hormone. I talked it over with my vet and she wanted me to try to use herbal supplements first so back to Smart Pak I went! I started noticing results in the first week!! Now she will stand still and actually relax a leg when she is on the cross ties, she doesn't care if her belly is brushed and she is way better riding too!! We went to our first open show this last weekend and she quickly calmed down to the new environment and acted like a 20 year old horse instead of a 4 year old!! Lesson learned, she will stay on this supplement!! The cost is well worth the benefits!!!!!

    Rated 2 out of 5 by from I have been using the Smartmare Harmony for about 6 weeks now, and have noticed very little change in my mare' s stall behavior. That is the only time that she shows bad behavior. Unfortunately the Smartmare Harmony did not work for my mare.

    Rated 5 out of 5 by from LOVE MARE HARMONY! I have awesome mare but us mare owners know when they are on their cycles some can be a challenge. My mare is very moody and likes to put up a fight when on her cycle. Since she has been on Mare Harmony she has been calm. She rode so well I didn't even notice she was on her cycle. I really love mare harmony and haven't had and moody mare fits since she has been on it. I highly recommend Mare Harmony.

    Rated 4 out of 5 by from Seems to make a difference... My 24-year-old mare has a ruined cycle from previous mismanagement. She's almost always in heat or showing signs thereof, and the introduction of teaser stallions on the neighboring farm isn't helping. She's been on SmartMare Harmony pellets, including the loading dose and maintenance dose, for about six weeks. It's not a miracle product thus far, but it does seem to have an effect, and she seems more comfortable, if not more manageable.

    Rated 5 out of 5 by from Seems to be working Horse has been on this product almost 3 months. Stopped it once and the cranky mood returned, restarted and it went away. Not all of it, she is a mare after all, but the witchy part greatly improved. Much easier to deal with and isn't as nasty with the cows. Still have to watch for kicking when around other mares.
    Date published: 2017-05-17
    Rated 5 out of 5 by from So far it works! My mare hasn't completely changed BUT she is much calmer and doesn't seem to be so stressed out. As a result, she's gaining weight she lost running the pasture any time one of her pasture mates left her behind.

    Rated 2 out of 5 by from Didn't see any effect... Fed as recommended for a month with no noticible change in my mares comfort or behavior. Due to my lack of success with other supplements on her other than Moody Mare I'm not surprised but decided to discontinue feeding smartMare pellets since no improvement was observed.

    Rated 5 out of 5 by from I think it has helped I put my moody mare on this over a month ago. She would be uncooperative to work with and throw tempers. Within a week of giving this she seemed to mellow out. I don't know if it was a co-insidence or if it really worked but I'm a little nervous about stopping the supplement. She had been sent away to be trained, which was a bust, and had come back with a worse temper. Couldn't ride her. Once I started her on this she started to get easier to deal with til I was finally able to ride her. She's still temperamental with some of the other animals but I think that part is just her personality, she wants to be the one in charge. But her mood has gotten better.

    Rated 5 out of 5 by from This supplement works amazing and is affordable My mare was super agitated all the time, super spooky, jumpy, hot and was very hard for her to focus. After only about two weeks on this product I noticed her starting to quiet and work a little better. Now she's been on it for about two months and she's incredibly different! Not so mare-ish in heat and is a much happier and quieter mare!!

    Rated 5 out of 5 by from Crazy Ollie Oliver was given to me to be a companion for my Halflinger Maggie that injured her leg. It did not work as well as I imagined. He got very jealous when he wasn't the center of attention. When I needed to change Maggies bandages, Oliver would stick his head in her stall and make a rukus. These Pellets def. made him relax enough for me to change the bandage in a somewhat peaceful setting. I donated him to a Therapeutic Horse Stable. Going to miss him soo much, though in exchange I got 3 minis. Soo my hands are full. Bye Olive :( Thanks for the helpful pellets though.

    Rated 5 out of 5 by from Great supplement! I have had my mare on this for about 2 months now and I can't believe the difference. This supplement doesn't just drug her up to make her more compliant like I have found with other similar products. This product keeps my mare alert and ready for anything while helping to regulate her hormones. I have found her to be a bit more relaxed and her heat cycle was so much more regular and she didn't appear aggressive or irritable while in heat. I would recommend this for anyone that has a mare struggling to regulate their hormones on their own. Great supplement!

    Rated 2 out of 5 by from My vet recommended this for my young mare whose having trouble coming off of cycling throught the winter.
