Poseidon Animal Health

Daily Support, Complete Care for horses and dogs.

Poseidon Animal Health was created by Linda Goldspink-Lord, dog lover and proud owner of 12 horses, with over 40 years of riding, training, breeding and competing experience across various disciplines.

Wellness from within

"Horses have always been a big part of my life, and I'd always tried to feed my horses as naturally as possible. But I was having serious ongoing trouble with one particular horse. He was losing weight, having trouble with his right canter lead, grinding his teeth, and I was spending a fortune on supplements! Then one day he bolted from under my daughter, putting her in hospital.

My journey to find the right solution for him led me to create the Poseidon Animal Health brand, where we are PASSIONATE about supplements that provide daily care and complete support for gut health in horses, and our precious dogs."

World-leading gut health supplements

Why are Poseidon Animal Health’s products a staple in the diets of horses in elite eventing, high-level showing and jumping, grand prix dressage, barrel racing and western disciplines, racing - and even lucky geriatrics living their well earned retirement?

Why do so many dog owners choose our gut health supplements to support their dogs' wellbeing?

Because the evidence is in - True health begins in the gut, and it can change everything for your dog or horse. See reviews and before and afters from dog lovers and horse lovers.

Linda's success with improving her own gut health inspired her to learn about horse nutrition and the role of the hindgut in horses. In collaboration with leading animal and equine nutritionists Linda explored the effect that diet, mycotoxins and stress have on a horse, and in particular the horse’s gut.

She was determined to create the best possible evidence based gut health supplement for horses in the world - to improve horses wellbeing, eliminate the need for a plethora of supplements, and save horse owners time and money.

The initial trial on 17 horses - mostly her own - showed significant changes, even in the horses who had been performing really well. The supplement formulation was tweaked to be even higher quality then trialled across 40 more horses in various disciplines.

Common changes in the horses health included:

Better weight gain
Calmer horses, no more head shaking
Greater elevation in movements
Shinier glossy coats, better hoof quality and growth
Fussy eaters had a better appetite
Improved feed conversion
Less scouring while travelling

A third trial of Digestive EQ was run with the guidance of a leading Equine Veterinarian Professor on a number of horses, with evidence collected for weight gain, measurable health changes and palatability. The feedback was positive and with a few texture adjustments, Digestive EQ was ready for market in November 2017. In line with our committment to delivering the highest quality product possible, our products are made in Australia, in a quality-controlled environment which meets Government standards.

We believe in providing real support, so we are available to answer your questions, and have dedicated trained distributors across Australia. We truly listen to you and your dog or horse’s needs.

We are dedicated to helping animal owners make informed decisions about feeding your dog or horse for great gut health - to maximise performance, health, longevity - and economy! This is why we continually work with animal health experts with PhDs in Equine Nutrition and Gut Health to create and share educational content - see our LEARN section in the menu for articles, videos and fact sheets.

We’re excited for you to see the changes Poseidon Animal Health can provide for your horses and dogs.

We love dogs too

After welcoming a new puppy Oscar into her family’s lives, Linda decided the time was right to create a gut health supplement for her other furry four-legged friends.

Working with a highly-skilled team including a holistic veterinarian, canine nutritionist/naturopath, and a microbiologist, Poseidon Animal Health formulated their first product: Digestive K9.

Linda's journey

"It started with my own health crisis after suffering encephalitis - over ten years later I was still having major problems with my health, energy levels, memory and concentration. I investigated dietary changes and learnt about the link between gut bacteria, health and emotions - when I started looking after my gut with my diet I was amazed at the improvement I experienced."
