Don't Doubt This Product's Usefulness
April 22, 2017
At one point, we thought of saving some money by changing to a different product. A visiting vet, who was looking at our horse, recommended putting him back on Cosequin ASU immediately. Our regular vet is what I consider a 'minimalist', but recommends this as the only feed-through joint support product that he would recommend.

Wife insists on using this on her horse.

Ordered Cosequin ASU for my wife to use on her aging horse. She maintains that this is the best product she has used for her horse's joints and has had excellent results.

Barrel racing every weekend is tough on a horse. Giving a scoop every day ensures continued joint health and promotes longevity for additional runs for years to come.

I love this product
September 18, 2015
I have been using this for years at the recommendation of my vet, who was impressed that my horse's hock injection lasted 2.5 years. I can't say for sure that it was due to the daily use of this product, but I'm going to keep using it.

Excellent product

My mare is now 23 yrs old and my vet continues to say how wonderful she looks. We have had her on Cosequin since she was 16 yrs old as a preventive for arthritic problems. I recently switched her to Cosequin ASU at my vet's recommendation. She is doing very well and moves well. I am not changing a thing!

Worth the price!

I'm convinced this works! My eventer is now 18. He has been getting Cosequin for most of his life and, so far, NO arthritis issues. Worth the price! I've even started to take the human version for my crummy knees and it's helping me too!

I've been using this on my horse for a couple of years now, he eats it with no problem in a little bit of grain, and has been very sound since adding to his diet. I would recommend adding to ensure soundness.

My older mare is now living her retirement years very happy and as close to pain free as I could hope for, Thanks to this great product. Shipping was fast and easy and I will continue to purchase my horse supplies through your company...a big thanks!!
Love product/discounted price but about to expire

Think this is a wonderful product and was very excited to find such a discounted price (~50%). Should have guessed it was close to expiry date, but would have been nice if description had revealed this info.

Great product for an older horse
February 19, 2013
My 30 year old Arab gelding was starting to have difficulty holding a foot up for the farrier so I knew I had to do something for him. I tried this product on the advice of my vet. After only a couple of weeks on it I noticed my gelding started doing little bucks when he and the other horses ran out to the pasture! He is also much more comfortable holding a leg up for a hoof trimming. Entirely Pets had the best price on this expensive product and I was able to do a search for a promo code to bring the price down further!

Good support

Our 4 year old just went through hock sack surgery and a series of metabolic problems post surgery. We credit Cosequin ASU for giving him the joint strength to make it though these traumas and soundly return to working under saddle.

Cosequin ASU
December 24, 2012
I have been using this product for about 2 years.
I have seen great improvement in the overall well-being and movement of my two older geldings who get Cosequin. One is an 18-year-old thoroughbred gelding who has been a jumper all his life. The other is a 23-year-old quarter horse who has been a professional roping horse his whole life. They now frolic in the field like young horses, and appear to be pain-free and enjoying life. Also, your company provides excellent service when I place an order.

Certainly worth trying
November 13, 2012
I have a young TB who was diagnosed with severe navicular syndrome. Did the Tildren, special shoes etc and he was still very lame. Vet said all that was left was a neurectomy. (no way) I wasn't giving up and took a natural approach. Removed his shoes, started him on Formula For Feet and the Cosequin ASU (I did my research, all reviews pointed to ASU as did my Vet). I also changed his grain. He isn't 100% but he is close FAR better than before. I am even riding him soundly on good footing. As I did all the changes at the same time it's hard to say if one did more than the other (the barefoot for certain) but I am convinced this product is working for him. I believe it enough to spend the money as it is expensive. (I would likely give 5 stars if it wasn't so costly) I would definitely recommend it.

Outstanding product

I have 2 donkeys on this, one is over 35 years old & the other one spent the 1st part of his life, being used by cowboys for roping practice. The old guy had a broken hip & blown knee, the other one's legs are arthritic from being roped many times. Both of them stay comfortable when given Cosequin ASU

I have two older horses that have worked hard their whole lives. One is a 23 year old roping gelding, one is a 17 year old jumper. They both were showing signs of wear and tear on their joints. I heard that Cosequin ASU was a good product, and decided to try it. They have both shown amazing improvement in the way they feel. When you see them out in the pasture, playing like young colts, you would never guess their ages. I will continue to give them Cosequin for the rest of their lives. They deserve the best!

Vet recommended my horses need the daily suppliment for their working lives. I depend upon Entirely Pets to always ship my order in a timely manner so the horses never miss their daily dose. I have never been disappointed.

Product and prices are the best!

I've been giving my older horse Cosequin ASU for 2 yrs. I noticed a significant improvement in his movement and comfort when I started at the recommendation of my veterinarian. I won't be without it and Entirely Pets has the best price anywhere with fast, free shipping. I got an expired container last shipment which was resolved immediately. They sent me a new package and picked up the old. Love the customer service!

I recently purchased Cosequin ASU from Entirely Pets. I've used the product before for my jumper, and feel it has been very effective in treating his hocks for arthritis.
My rave review is for Entirely Pets for the fantastic service I received. Shipping was so fast, I couldn't believe it when I received my order only 2 days after I placed it! Thank you!

I know not everyone will have the same experience, but the Cosequin ASU has made a difference in my older trail horse. He injured his shoulder and has had intermittent lameness; the Cosequin ASU has alleviated a lot of his symptoms. I also greatly appreciated the price break I received.

Absolutely Amazing
December 28, 2011
My 18 year old gelding foundered and we were getting him through that but he just wasn't coming back as fast as he should. I thought there might be another issue going on.

An easy keeper, his weight was up so I thought arthritis had to be an issue with his size,weight and age. I added this supplement to his food and he is now galloping all over the fields.

My horse is very picky about what goes in his food, but he loves this stuff! If only they made wormers and other meds like this!
