PREBIOTIC POWERHOUSE

These feed good microbes to stay in your dog’s gut and thrive. Different microbes like different prebiotics. We give the good guys a reason to stick around.

WHY PROBIOTICS ALONE DON’T WORK

Probiotic do not survive the gut of many dogs. They do not live in the gut. They go right out the other end. Sustain™ is food-based and designed to correct this issue and support the gut to heal. How? Through valuable phytochemicals, micronutrients, and fibers.

FERMENTATION IS THE WAY

For the same reason dogs bury bones, bury prey, and eat the gut contents of their prey, we ferment. It also makes everything easier to digest and to absorb.

FAQ

Use it as a topper or mix in to any food (raw, kibble, or wet). Add up to 2 teaspoon per 10-20 pounds of your dog's weight.

Feed less to start if you'd like to get them used to it.  Give it once a day.

💦 Please add a little water to instantly hydrate the ingredients.  Mix well and serve.

A 6.5oz pack contains 97 tsp servings. You can feed 2 tsp per 20lbs of your dog's weight. That means this trial pack lasts a 20lb dog 48 days.

It's actually made for both dogs and cats, so YES!

It's 100% different. All different ingredients. In fact, Daily has no grasses or sprouts. So you can feed with Daily and even reduce your Daily serving size per day and add in Youthful Grasses & Sprouts or alternate the formulas each day. Dr. Billinghurst says, have fun with it. See how adding in this formula can enhance your dog's health!

Yes! We made it to compliment our product Daily. It can help you save money by incorporating it into your dog's routine.

We are proud to say, our ingredients are sourced from organic, biodynamic or regenerative farmers.  Organic is our minimum requirement.  We never ever allow ingredients that have pesticides or herbicides.   

Nothing is too good for our dog customers. Our ingredients are everything to us. 

We will continue to build amazing relationships with the finest farmers and ranchers on behalf of our customers.  

Dogs and cats eat the gut contents of their prey animals. Those contents are fermented. Well we wanted to create a formula as if their prey ate the ultimate diet of grasses and sprouts and they fermented in their stomach.
