Rated 5 out of 5 by from Helps keep shoes on my horse. My gelding was losing his front shoe. He has not lost one since I started giving the supplement.

Rated 5 out of 5 by from Perfect for your OTTB Since starting this supplement back in November of 2020 my OTTB finally has heels, and is so much more comfortable on hard surfaces. As far as taste goes, my boy eats it up right out of my hand. But he has and never will be picky, so I can't write a truly honest review for your picky ponies out there. I will continue this supplement as long as my horse is in work. I do have front shoes on him right now since we do a lot of trail riding, and he hasn't lost one yet. Very happy customer.

Rated 5 out of 5 by from Improvement! My horse had developed some thrush under 3 of his hooves in the humid summer weather, which is the first time I've seen it happen. My farrier recommended starting Farrier's Formula after he had trimmed back his hooves and cleaned them out. It seems to be working as the thrush is gone and the hooves aren't mushy like they were before starting this.

Rated 3 out of 5 by from Seems to work well so far I have a new ottb and this was recommended to help thicken his thin soles. We just took off his back shoes so I was concerned he would be sore. He was sore for a week but has been good since. Fingers crossed for the future.

Rated 5 out of 5 by from I had a horse founder almost 2 years ago! Put her on this and within about 6-8 months she had so much sole growth the Ferrier was shocked! She now is cleared and running around like normal again!

Rated 4 out of 5 by from Expensive... I guess I see results... Expensive supplement but I did notice a difference in my horses hooves when he wasn’t on the double strength and since he’s back on this he’s been a little better at keeping shoes on!

Rated 5 out of 5 by from Must have good feet! I have been using for about a year now and it has made a big difference in the quality of the hoof and i think the mane and tail as well!

Rated 5 out of 5 by from Works Well to Maintain Overall Hoof Heath My horses, now horse, have been on Farrier's Formula now for about 10 years. My first mare had soft soles and had trouble building a heel, my farrier recommended this product and after doing some quick research I immediately purchased it for her. It did take a bit of time - nothing is over-night except for injuries with horses :) - but she began building strong hoof that held her shoes well with no cracking and no issues until the end of her life. My second horse had issues with thrush and holding his shoes while building his hooves back up. As I had my mare on FFDS, I put him on it shortly after he began having some issues adjusting from stall 22/7 to being slowly introduced outside for longer periods of time over pasture. He, along with my mare, often got complemented my by farrier at how healthy, solid, and problem-free their hooves were. He in the last couple years of his life also had very few problems with his hooves, aside from bone/etc problems. My current horse is on FFDS as of present, and I find his hooves from day one have had few issues. I find this keeps his hooves healthy, strong, and able to handle the weather and seasonal changes we have in CO. I will probably always keep my horses on Farriers Formula supplement - perhaps not always the double strength - but I find it really helps troubled and healthy hooves alike to maintain structure, gain and maintain strength, and to be really solid overall. No hoof, no horse; therefore I recommend this product immediately when asked by fellow boarders what my horse is on.

Rated 5 out of 5 by from Hardened his feet even with all this rain! Rio was throwing shoes due to soft hooves. After 6 weeks of the double strength my farrier noticed a huge improvement in the hardness of his hooves. I'll be able to put shoes back on him by Spring riding time!

Rated 5 out of 5 by from Great hoof supplement My horse has been on this for a while and you can see the difference. Highly recommended by my farrier and great price!
Date published: 2020-12-24
Rated 3 out of 5 by from Well, they eat it. This product has long been touted as the gold standard for a healthy hoof supplement. My older gelding is starting to have issues with quality of his hoof growth so I thought it would be time to give it a try. However, since I only received it in the middle of October how can I vouch for it's claims. It takes a year for a horses' foot to be replaced with new growth. Maybe as me again this time next year?

Rated 5 out of 5 by from Best Hoof Supplement Out There I have two thoroughbreds in farrier’s formula. After trying this supplement, I will never go back. Both horses are doing great on it and I have seen more healthy hoof growth than ever before. Definitely worth its price.
