You do not have to decide today for the rest of your life. Today, maybe is enough.
The Gut-Ready Method
7 probiotic strains, 350 million CFUs per serving, entering the gut routine every day.
Prebiotic inulin from chicory root: food for the good bacteria, so they arrive and find something to eat.
Herbal and nutritional blend with hydrolyzed fish collagen, flaxseed, fennel, L-glutamine, turmeric, PEA, kelp, chlorella and chlorophyllin.
Beef liver flavor and liquid drops: once a day, directly in the mouth or mixed with the food your pet already eats.
How to use
Shake gently. Give once a day, preferably with the first meal, directly in the mouth or mixed with food. Clean the dropper and refrigerate after opening. Always follow the directions on your bottle.
| Weight | Daily serving |
|---|---|
| 1–25 lbs | 0.5 mL |
| 26–50 lbs | 1.0 mL |
| 51–75 lbs | 1.5 mL |
| 76+ lbs | 2.0 mL |
| Weight | Daily serving |
|---|---|
| Up to 5 lbs | 0.33 mL |
| 6–10 lbs | 0.66 mL |
| 11–15 lbs | 1.00 mL |
| 16–20 lbs | 1.33 mL |
For both: adult dogs and adult cats, with the daily serving adjusted by weight. The drop format exists exactly because of the cat that turns away and the dog that spits out capsules.
Drops in food are not the same as a capsule hidden in cheese. Some homes get it right on the first try; others take 2 or 3 days testing the time of day and the mix. And if it still does not make sense for you, the 30-day guarantee covers your decision.
If you simply want to begin, choose 1 bottle. If you want the path that best matches the method, choose 3 bottles: it gives the routine time to stop being a test and become a base. If you already know that starting and stopping is what feeds the cycle, choose 6 bottles for the lowest cost per bottle.
Every pet has their own rhythm, and we will not invent a date. The routine acts first where it lives, so gas, odor and stool are the first things to observe. Coat, skin, paw and ears are conversations of weeks, not days. Avoid changing several things at the same time so you can read the results clearly.
Yes. You do not need to change food to begin. Keeping the rest of the routine steady also makes it easier to observe how your pet responds.
The gut is not a CFU auction, it is an environment. BYON Pet combines 7 strains, a prebiotic to feed the bacteria, a support blend and daily drops your pet can actually take. Look at the architecture, not the isolated number.
BYON Pet is made in the United States in an FDA-registered facility and passed 11 quality tests using USP and AFNOR methods, with negative pathogen results. Follow the label: do not use in pets with epilepsy, kidney disease or liver disease, in pregnant or nursing animals, or in pets under 6 months, and talk to your veterinarian first if your pet takes any medication.
Every order is covered by a 30-day money-back guarantee. If BYON Pet does not feel like the right fit for your household, contact our support team within 30 days of delivery.
