Prices as shown on the Mighty K9 store on October 12, 2026: 1 bottle $64.99 (sale price), 3 bottles $269.97 and 6 bottles $539.94 ($89.99 a bottle; the store showed no bulk discount, and its bundle selector also listed 1 bottle at $89.99). Free shipping on orders over $100. The checkout shows the final total before you pay; prices can change. Before you pay, the secure order page lists the final total, shipping and tax. We show no struck-through "was" prices, since we cannot check that anyone ever paid them.
Each pack holds the same 60 mL bottle of olive oil with ESS60 (C60) and bacon flavor. Pick the pack by how long you want to try the drops, not by the size of your dog, because the label lists the same 2 mL serving for every dog.

Side by side
How many days does each Mighty K9 pack last?
One bottle is one month at the label serving. The rest is simple multiplication.
| Pack | 1 Bottle | 3 Bottles | 6 Bottles |
|---|---|---|---|
| Bottles | 1 | 3 | 6 |
| Oil | 60 mL | 180 mL | 360 mL |
| Servings (2 mL) and days | 30 | 90 | 180 |
| Pack total | $64.99 | $269.97 | $539.94 |
| Price per bottle | $64.99 | $89.99 | $89.99 |
| Cost per day | about $2.17 | about $3.00 | about $3.00 |
| Shipping | Free over $100 (sales page) | Free over $100 (sales page) | Free over $100 (sales page) |
| Covers the 30-day window | Yes | Yes | Yes |
The math comes straight from the Guaranteed Analysis: 2 mL per serving and 30 servings per container. At one serving a day, a bottle lasts 30 days. Three bottles last about 90 days and six last about 180. If your vet suggests a different amount, the days change with it. Check the serving on the how to use page.

Should I buy one bottle or three?
One bottle is enough to judge Mighty K9 on your own dog inside the 30-day money-back window. The sales FAQ suggests starting with at least three bottles. That is the brand's sales advice, not a dosing rule, and no study sets a three-month minimum.
01
1 bottle: test it
Thirty days covers the whole guarantee window. You learn if your dog likes the taste, if the oil sits well, and if you keep the routine.
02
3 bottles: follow the FAQ
Ninety days matches the sales FAQ's 8 to 12 week timeline. Keep in mind that the refund window still closes at day 30.
03
6 bottles: fewest reorders
Half a year of drops in one box. It suits owners who have already tried the product and want to skip reordering.
Read what to watch for on the results timeline page.
Shipping
Does Mighty K9 ship free?
The sales page says free shipping on orders over $100. At the prices we saw on October 12, 2026, the 3 and 6 bottle packs ($269.97 and $539.94) clear that line and a single bottle at $64.99 does not. Check the shipping row on the order page before you pay.
Orders ship from the U.S. unless the sales page says otherwise, and the tracking link arrives in your order email. Delivery times are not published. Ask the order desk at +1 (302) 200-3480 if you need the bottles by a certain date. More on the shipping page.

- Pay only on the secure order page that opens from an order button here.

FAQ
Mighty K9 pricing FAQ
How much does Mighty K9 cost per bottle?
On October 12, 2026 the Mighty K9 store showed one bottle at $64.99 (sale price). The 3 bottle pack was $269.97 and the 6 bottle pack $539.94, which is $89.99 a bottle, so there was no bulk discount. Prices can change; the order page shows the total, shipping and tax before you pay.
Is the 6-bottle pack of Mighty K9 worth it?
It makes sense once you know your dog does well on the drops. Six bottles were $539.94 when we checked, about $3.00 a day for 180 days, with no bulk discount over single packs. If you have never tried Mighty K9, one bottle covers the full 30-day money-back window and tells you whether your dog eats it.
Does Mighty K9 have a discount code or coupon?
We know of no discount code, and we make no discount claims. Be careful with coupon sites that send you to unknown checkouts. Buy only through a secure order page you trust, and compare the final total there before you pay.
Is there a Mighty K9 subscription or autoship?
We have not seen a subscription offer on the sales page, and we make no subscription claims. Read the order page carefully before you pay so you know if any repeat charge is included. If you see one you did not expect, call the order desk at +1 (302) 200-3480.
Why are Mighty K9 prices different on other websites?
Prices change, and the store itself listed one bottle at $64.99 as a sale price while its bundle selector showed $89.99. Other sites may also be old pages or unknown resellers. The checkout that opens from our order buttons is the only total we point buyers to.
How many bottles of Mighty K9 should I start with?
One bottle is enough to judge Mighty K9 within the 30-day money-back window. The sales FAQ suggests starting with at least three bottles, which matches its 8 to 12 week timeline. That timeline is not backed by a study and runs past the refund window.
Does Mighty K9 come with free shipping?
The sales page says free shipping on orders over $100. At the October 12, 2026 store prices, the 3 and 6 bottle packs qualify and a single $64.99 bottle does not. The shipping line on the order page shows the real cost before you pay.
