(CNN) Wooden Phone was never asked whether he wanted to race. Born in 1997, the dull-brown thoroughbred didn't show initial signs of greatness, but the horse would net more than $800,000 in winnings during his career.

A warrior on the track, he kept coming back from severe injuries to beat likely champions. His temperament wasn't suited for the highly stressful industry -- trainers called him "difficult," a diva.

After his racing career ended at age 9, retirement didn't suit him either.

Easily agitated, Wooden Phone would pop his lip -- the equivalent of a child sucking his thumb. He was nervous just leaving the pasture.

Anyone who has been around thoroughbreds will tell you that these horses love a job, and now Wooden Phone's duties were outsourced to younger, stronger workers. Intelligent and sensitive with a drive to please, racehorses like him also crave human attention and care.

Unfortunately, when a racing or breeding career ends, thoroughbreds can quickly become useless to their owners. The injuries compound and when money and options run out, convenience leads them away from the stables and into the slaughterhouse.

The racing industry has worked to provide retirement programs and track policies that prevent slaughter. But Brown wants to see even more accountability: transparency of medical records from owner to owner, as well as support for programs that rehab ex-racehorses.

"I think all of us who make our living with horses have an obligation to give something back and provide for the welfare of these horses," Dan Rosenberg, head of Thoroughbred Charities, said.

LOPE Texas is just one of hundreds of organizations across the country dedicated to rescuing and rehabilitating ex-racehorses for new homes and purposes.

Suzanne Minter, an experienced rider volunteering her time at LOPE, first met Wooden Phone five years ago. His personality captured her heart.

LOPE founder Lynn Reardon was surprised by Minter's soft spot for the horse -- Wooden Phone was not an adoption candidate after his many injuries. And then, there were the stress issues.

Ex-racehorses get a bad reputation for being aggressively energetic, although their "bad manners" come from training gaps. With the right rehab techniques, they can be gentle enough to work with veterans who suffer from PTSD and children with autism.

Wooden Phone and Suzanne Minter quickly bonded.

Minter was dedicated to rehabbing Wooden Phone, although it became more sporadic when she had unexpected abdominal surgery. She wasn't able to ride, but she would sit on his back as he gently stood still. As she had helped him, he took care of her in return.

"He fell in love with her. He just melted every time she came around. It was a match that was so clear the moment he met her," Reardon said. Minter adopted him.

The 19-year-old horse, once known for the foamy stress sweat on his neck, is now the gentlest horse in the barn. Together, Minter and the newly named Watson have trained for dressage events.

The lip popping has evolved into quirks, such as holding one brush in his mouth while Minter uses the other to groom him, grabbing people's jackets with his teeth for fun or curiously following his new obsession: ponies.

"Ex-racehorses get overlooked sometimes because people just think they are fast, but they have a lot of heart," Minter said. "I think they are all looking for a person of their own."

Turning hope into help

"There are so many places for these horses other than slaughter," Cindy Gendron of the Homes for Horses Coalition said. "Now people are using them for therapeutic riding, equine-assisted psychotherapy, show events and family horses."

The Homes for Horses Coalition aims not only to end horse slaughter, but to promote growth and collaboration in the horse rescue and protection community. Supported by the ASPCA, the Animal Welfare Institute and the Humane Society of the United States, this coalition in Washington is an umbrella for 240 organizations.

CANTER , a member of the coalition, was one of the first groups to create an online showcase of ex-racehorses in 1997. It's an all-volunteer organization with affiliates across the country, where people scour the "backsides" of racetracks every weekend and document the horses up for sale, executive director Nancy Koch said.

"The racetrack is quite a closed-in world. Not everyone can wander into the backside, you need to be escorted otherwise. We broke a lot of barriers that way," Koch said.

Other CANTER affiliates in "phase two" have taken in horses and provided rehabilitation so they can find new homes. They placed more than a thousand horses in 2012, according to the Homes for Horses Coalition.

Volunteer-based adoption farms, such as Kim Smith's Second Stride near Churchill Downs, follow a similar model and work to connect owners and horses. Like LOPE, an extensive adoption process ensures that each new home is a good fit and requires follow-ups in the months and years ahead. If the home doesn't work out, they take the horse back.

These farms also make thoroughbreds available to people who may not have five figures to spend on a horse but have the time and resources to care for one, administrative manager Leslie Pratt said.

Life after the track

"In the horse adoption world, ex-racehorses are seen as the equivalent of pit bulls," Reardon said. "People think they are edgy, so you have to do a lot of myth-busting."

Retraining can ease the issues that create negative stereotypes about ex-racers. And helping these horses can help heal the trainers, too.

The James River chapter of the Thoroughbred Retirement Foundation pairs men at a correctional facility with ex-racehorses. The horses are cared for by men who work through and graduate from a groom elite training program, which trains them for a job once they are released.

Anne Tucker, the foundation's president, likes to tell the story of Happy and Will. Happy, a nervous thoroughbred, was kicked in the face by another horse while trying to assert her authority after arriving at James River. Will was the insecure young inmate taking care of her.

Will and Happy's bond helped them to heal each other.

"It's hard to say whether Will gave Happy confidence, or Happy gave Will confidence," Tucker said. "Horses look at everyone on even footing. The men have made some mistakes, but they aren't bad people. They just need someone to confirm that, and that's what the horses do."

The pair bonded and healed one another. Happy was adopted after a full recovery, and Will has been released and is working on a local thoroughbred breeding farm.

The golden years

"Some of these horses are like your best athletes -- they gave everything to the sport, and they got banged up in the process," said Michael Blowen, founder of Old Friends Thoroughbred Retirement Center . "To me, this is like having Larry Bird in my backyard."

Formerly with the Boston Globe, Blowen had racehorses at Suffolk Downs. He quickly learned that when the horses couldn't race anymore, they weren't "going to a riding academy in Maine" as he was told -- they were going to slaughter. He decided to dedicate the rest of his life to offering ex-racehorses a retirement paradise.

Old Friends' locations care for more than 160 horses across three states, located near racetracks so fans can come visit the "retired athletes" in big paddocks.

"It is the equine equivalent of retiring and living on a golf course, except they eat the greens," Blowen said.

Photos: Photos: 'Hat's Off to the Horses' – Sally Steinmann has never owned a horse, but her heart is full of love for them. Now, she creates hats in honor of retired racehorses at Old Friends . A hat is auctioned off to benefit their welfare each month for six months, leading up to the Kentucky Derby. Pictured here is a hat designed in honor of retiree Popcorn Deelites. Hide Caption 1 of 23 Photos: Rapid Redux – Rapid Redux retired to Old Friends in May 2012 after an impressive 22 consecutive victories. "His contribution to the sport of racing in ordinary races at blue-collar tracks called attention to the achievements of the majority of horses, who never win a stakes but provide the daily thrills and livelihood of the sport," according to Old Friends. Hide Caption 2 of 23 Photos: The Rapid Redux hat – To honor Rapid Redux's 22 consecutive wins, Steinmann created 22 rose curls to adorn this hat, which utilizes the distinctive pink and yellow racing silks of owner Robert Cole Jr.'s racing stable. Hide Caption 3 of 23 Photos: Benburb – Before retiring to Old Friends in 2008, Benburb finished his racing career with seven wins out of 22 starts and earnings of $1,159,904. He passed away in 2012. "Bennie," like many gray horses, had complications from melanoma. Hide Caption 4 of 23 Photos: The Benburb hat – Steinmann used nearly 12 yards of silver, black, ivory and white tulle layers to translate Benburb's legacy into fabric for the January 2012 auction. Hide Caption 5 of 23 Photos: Sarava – Sarava arrived at Old Friends in September 2012. He won the Belmont Stakes in 2002 and was the longest shot ever to win the race. His former owner, Gary Drake, still comes to visit him every month and donated more than $30,000 to his aftercare.

Hide Caption 6 of 23 Photos: The Sarava hat – To honor Sarava, Steinmann wanted to highlight the horse's nearly black coloring with his racing silk colors of red and white, as well as red roses to represent the Kentucky Derby and white carnations for the Belmont Stakes. Hide Caption 7 of 23 Photos: Ogygian – Considered one of the fastest runners of his generation, Ogygian is also known for his breeding. As a stallion, he sired 23 stakes winners. Old Friends raised the money to bring him back to the United States after his breeding career in Japan. Hide Caption 8 of 23 Photos: The Ogygian hat – When it comes to translating the legacy of a thoroughbred into a silk hat, Steinmann likes for her creations to mirror the rippling motion of a racehorse. To achieve this, she used rows and rows of alternating tulle layers, repeated under the brim as well. Hide Caption 9 of 23 Photos: Bull Inthe Heather – Bull Inthe Heather (yep, that's how it's spelled), retired to Old Friends in 2006, is considered to be the greatest son of Ferdinand, who won the 1986 Kentucky Derby. The death of Ferdinand in a slaughterhouse in 2002 inspired the foundation of Old Friends. Hide Caption 10 of 23 Photos: The Bull Inthe Heather hat – Steinmann used her trademark silk "feathers" to mimic the horse's mane and tail, as well as his iconic blue-gray coloring and dark accents. Hide Caption 11 of 23 Photos: Wallenda – When Wallenda was brought home by Old Friends from his breeding career in Japan during April 2007, the Flying Wallendas themselves came out to the farm and put on a circus for the whole weekend, walking the high wire and wearing the silks the racehorse sported in the Kentucky Derby. Hide Caption 12 of 23 Photos: The Wallenda hat – Dogwood Stable's yellow and green polka dot racing silks inspired the trimming colors for Wallenda's hat. Several strands of the great stallion's tail hairs were braided and woven into the trim of the hat itself. Hide Caption 13 of 23 Photos: Creator – Creator was owned by Sheikh Mohammed bin Rashid al-Maktoum, the ruler of Dubai and overseer of the world-renowned Godolphin Stables. He had a successful career and was retrieved from Japan in 2004 by Old Friends. Hide Caption 14 of 23 Photos: The Creator hat – Steinmann purposefully made this hat asymmetrical because Creator is known for striking particular poses with his forelock to the side. Hide Caption 15 of 23 Photos: Arson Squad – Arson Squad netted $1,190,181 during his racing career, but injuries ended it in 2011 during a training accident. His owner, Samantha Siegel, paid for his surgery, and he began his retirement with Old Friends in February 2012. Hide Caption 16 of 23 Photos: The Arson Squad hat – One of Steinmann's biggest creations, the Arson Squad hat, is 26 inches wide. She used a combination of his natural dark coloring and bright racing silks. The fanning black trim is meant to mimic his mane and tail. Hide Caption 17 of 23 Photos: Dancin' Renee – Dancin' Renee retired to Old Friends at the age of 20 in September 2012. In her banner year, 1997, she claimed seven consecutive victories and was crowned New York Horse of the Year. Hide Caption 18 of 23 Photos: The Dancin' Renee hat – Dancin' Renee was named after her owner's mother-in-law, Renee, who was a dancer in the Ziegfield Follies. To capture the playful nature of Ziegfield and the horse's stable colors, Steinmann played with contrasting textures and tones in her design. Hide Caption 19 of 23 Photos: Wooden Phone – Wooden Phone, now Watson, was a warrior of a racehorse who kept beating the odds and numerous injuries to defeat likely winners. During his retirement, Wooden Phone stayed at LOPE Texas, a thoroughbred adoption farm, and met his future owner, Suzanne Minter, while she was rehabbing him. Hide Caption 20 of 23 Photos: The Wooden Phone hat – To translate Wooden Phone's warm colors and "diva personality" in her design, Steinmann used dramatic layering of black and chocolate tulle around the brim. The looping and curling bow centerpiece is meant to reflect his "watchful eye" nature as well. Hide Caption 21 of 23 Photos: Barbaro – The beloved Barbaro won the Kentucky Derby in 2006 by seven lengths, but broke down in the Preakness Stakes after shattering his leg. He spent eight months at a treatment center, but succumbed to laminitis on January 29, 2007. Steinmann wanted to create a hat to remember Barbaro. Hide Caption 22 of 23 Photos: The Barbaro hat – "My way of coping with difficult things is to create, and I decided that I had to create a hat to honor Barbaro. I wanted it to be about his conformation, colors and his victories, not this completely sad memorial," Steinmann said. The red roses honor his incredible Derby win. Hide Caption 23 of 23

One resident, Clever Allemont , earned $316,329 during his eight wins. In 2009, he ended up in a kill pen in Kansas, deaf with one eye set in a graying face. He seemed to know he had reached the end, according to Kristin Chambers. Chambers and Diana Baker saved him from a trip to the slaughterhouse.

He was able to live out his golden years at Old Friends, gleefully rolling in the dirt and inspiring the groups of deaf children who toured the farm to see him. He passed away in 2014 at age 32.

Not every thoroughbred that gave their lives to racing has the same peaceful ending.

Old Friends has also inspired others to save ex-racehorses.

"I feel like these hats are little ambassadors and if anybody can learn about these horses, what we are trying to do and how much we all feel a responsibility to take care of them, then it's a really great thing," Steinmann said.

She studies photos and old racing film to craft hats that represent the horses, translating their legacies into silk dupioni with vivid trims. While the hats are extravagant pieces of wearable art, they are also creative pieces of awareness.

"Michael said we each get a dot, and this is his," Steinmann said. "I just want to connect our dots. We all have something we wish more than anything else that we could change in this world."

Inside and outside the racing industry, ex-racehorse welfare is a world of slowly connecting dots.

These retired horses are returning the favor by enriching the lives of the humans working to save them.

"People connect well with horses because they are gentle, instinctive creatures," Gendron said. "Just to lay your hands on a warm, powerful horse that puts his head down and looks you in the eyes is an amazing feeling, especially for someone who is in physical or emotional turmoil. Horses seem to sense that, understand it and take care of people."
