Questions & Answers

6 Customer Questions

Is this product safe for race horses in the track or is this product illegal.

Answer by Chewy • Mar 30, 2020
This supplement is a show-safe formula and is safe for use at the race track (and all other competition types).

Can I double the dose of this supplement?

Answer by Chewy • Apr 19, 2023
The serving sizes are based off of the average 1,100-pound horse. Serving sizes may be adjusted up or down in correspondence with weight. For instance, for a 500-pound pony, we would recommend feeding half the recommended daily serving. However, you may safely adjust the serving down or up, depending on your horse's needs.

Is this OK to feed to a yearling?

Answer by Chewy • Aug 30, 2023
This horse supplement is intended for adult horses only.

Can this product be given to dogs?

Answer by Chewy • Jan 11, 2026
This product is for equine use only.

Calming effect without causing dull sluggish behavior.

I have been using this product for well over a year. It works great on my high strung mare. She was not pleasant to be with when I first got her. I considered selling her because she was not what I wanted in a horse. I enjoy grooming and just being around my horses in addition to riding them. She never tried to kick, bite or anything but she did not like any attention or ground handling. She would try to walk away when I tried to let her stand ground tied. She did not like being shod and would try to get away from the farrier with everything in her. The farrier that I used told me he would only shoe her sedated. That worried me for her and him. I was afraid that she could fall and get hurt or hurt him. I researched natural herbs and ways of naturally calming her. I tried a couple that did nothing. I happened upon 707 products and after reading the product ingredients, the lack of things that could hurt her in the long run, I ordered my first bag. When I got it, I introduced it to her slowly. I took about a week to really give her the full recommended dose. After about two weeks, I started to notice a very slight difference in her. I kept using the product with the hope of improvement. Within a month of using 707 Calming she started to really show behavior improvement. I had taken to another place for shoeing after my regular farrier said he would only shoe her sedated. They too had some problem with her but this was before I had put her on the 707 product. When I took her back there eight weeks later, could not believe the difference in her. I told them about having her on 707 Calming supplement and that we were making progress with our ground training work. They were so impressed with the results that they saw. The CJ Farrier said that she seemed like a totally different horse. He complimented me on my training and help she had gotten from the supplement. I am a believer and plan to keep my girl on 707 Calming. If anyone is looking for something to change their horse over night, this is not the product. It takes a week or so to see full effect. A few doses can be missed and she does not slip back to her bad behavior. I am one happy customer. I highly recommend it.

Ease of giving the supplement.

We couldn’t tell that it calmed our gelding at all. He’s 20 years old and still has a big motor. Waste of time and money as far as we are concerned. May work

It really worked!

Another barn friend recommended 707 to help with my looky, looky gelding. I was hesitant at first, but I didn’t know what else I should do and so I gave it a try

Another barn friend recommended 707 to help with my looky, looky gelding. I was hesitant at first, but I didn’t know what else I should do and so I gave it a try. Within about two 2 weeks his attitude changed, and he was more confident of himself and not so hesitant to go into the trailer and different parts of the field. I noticed a big difference in that he stopped shying from certain odd objects in the barn and his confidence in himself actually was quite apparent. Highly recommend this product.!

My horse was very spooky, nervous and I didn't trust him for riding. I've only had him a year and since he's been on this he seems more attentive. I think next year

Works!!!

I have a Mustang that was anxious, constantly pacing, couldn't focus and i couldn't put weight on, or train him because of it. After 2 weeks on Formula 707 calming

I have a Mustang that was anxious, constantly pacing, couldn't focus and i couldn't put weight on, or train him because of it. After 2 weeks on Formula 707 calming pellets, he was noticeably more relaxed able to focus on me, and began eating more consistently. He doesn't act like a 'doped' horse, just a calmer, healthier minded one. I had done the calming pastes, CBD and most every other product at my usual feed store. I decided to try Formula 707, and not in glad i did! Reno just took first at Branded Bonanza Idaho in Handling and Conditioning and Trail. We placed 3rd overall!! Without Formula 707 we wouldn't of been able to even go to the competition.
