Price
How much does Mighty K9 cost?
One bottle of Mighty K9 is listed at $89.99. Every pack is priced at that same $89.99 per bottle, so the daily cost stays at about $3.00 no matter which pack you choose.
A bottle holds 60 mL (2 fl oz) dropper bottle. The label serving is 2 mL once a day, so one bottle gives 30 servings, or 30 days for one dog. Divide $89.99 by 30 days and you get about $3.00 a day.

Side by side
How do the Mighty K9 packs compare?
The packs differ only in how many bottles you get and whether shipping is free.
| Pack | 1 Bottle | 3 Bottles | 6 Bottles |
|---|---|---|---|
| Bottles | 1 | 3 | 6 |
| Servings (2 mL) | 30 | 90 | 180 |
| Days at 1 serving a day | 30 | 90 | 180 |
| Price per bottle | $89.99 | $89.99 | $89.99 |
| Pack total | $89.99 | $269.97 | $539.94 |
| Shipping | Shipping shown at checkout | Free U.S. shipping (over $100) | Free U.S. shipping (over $100) |
| Cost per day | about $3.00 | about $3.00 | about $3.00 |
| Covers the 30-day window | Yes | Yes | Yes |
The 1-bottle total is under $100, so its shipping is added at checkout. The 3- and 6-bottle packs are over $100 and ship free in the U.S., per the sales page.
Planner
How many bottles of Mighty K9 do you need?
You need one bottle for every 30 days of daily use for one dog. Slide the planner to the number of months you want to cover and it shows the bottles and the pack.
For 90 days you need 3 bottles: 3-bottle pack for $269.97.
Uses the pack prices above. Every pack costs the same per bottle, so pick the pack that matches how long you want to try it. Use this for planning only; the order page holds the final total.
How long each pack lasts against the 8-12 week claim
The sales page says most owners see changes in 2-3 weeks, with full results at weeks 8-12. That is the brand's claim, not a study result.
| Pack | Days of use | About how many weeks | Reaches week 12? |
|---|---|---|---|
| 1 bottle | 30 | 4 weeks | No, it ends around week 4 |
| 3 bottles | 90 | 12 to 13 weeks | Yes, just past week 12 |
| 6 bottles | 180 | 25 to 26 weeks | Yes, with room to spare |
Two dogs in one home use a bottle in 15 days. A 3-bottle pack then covers about 45 days, not 90.
Price check
Why did the Mighty K9 product page also show $64.99?
On October 11, 2026 the same product page that listed $89.99 also showed one bottle at a $64.99 sale price. At that price a bottle works out to about $2.17 a day. We show $89.99 as the standard price because the pack totals are built on it.
The order page total is final
Whatever any page says, the number on the secure order page before you pay is the one that counts. If it is higher than you expected, you can close it without paying.
We also do not print struck-through "was" prices or "save" percentages. We have no proof that anyone paid a higher price, so a crossed-out number would only make the deal look bigger than it is.
Shipping
Does Mighty K9 have free shipping?
Yes, on orders over $100. The sales page lists free U.S. shipping above that amount, which covers the 3-bottle and 6-bottle packs.
A single bottle at $89.99 is under the line. Its shipping cost appears at checkout before you pay, so you can see the full total first.
Orders ship from the U.S. with tracking in the order email. Delivery times are not published. Read the Mighty K9 shipping details for what to do with the bottles when they arrive.
Fair pricing
Why does every Mighty K9 pack cost the same per bottle?
The product page simply lists $89.99 for each bottle, whether you buy one, three or six. There is no bulk discount, so no pack is a better deal per bottle than another.
01
One bottle
Lowest total spend. Good if you want to see whether your dog accepts the bacon-flavored oil. Shipping is added because the total is under $100.
02
Three bottles
The sales page suggests starting with at least three. It covers about 90 days and ships free. The per-bottle price does not drop.
03
Six bottles
Fewer reorders if your dog already takes it daily. It is the biggest up-front spend, and the money-back window is still only 30 days.
Subscriptions
Is there a Mighty K9 subscription?
The sales page shows a "Subscribe & Save" option, but it does not explain the terms. We could not see the discount, how often bottles ship, or how to cancel.
If you pick that option, read the terms on the checkout page before you pay. Look for four things:
- The price per bottle on each repeat order.
- How often a new shipment is sent and charged.
- How to skip, pause or cancel, and by what date.
- Whether repeat orders are covered by the same 30-day money-back window.
Checklist
What should you check before you pay for Mighty K9?
Check the total, the shipping line and the guarantee before you click pay. A two-minute look now saves a phone call later.
- The total matches the pack you meant to buy: $89.99, $269.97 or $539.94, or a lower sale price if one is shown.
- Shipping reads free for orders over $100, or shows a cost for a single bottle.
- You save the confirmation email. The order ID in it is what the order desk asks for.
- You know the 30-day money-back terms, including that return shipping is on you.

FAQ
Mighty K9 price FAQ
How much does Mighty K9 cost per bottle?
On October 11, 2026 the product page listed Mighty K9 at $89.99 a bottle, the same in the 1, 3 and 6-bottle packs. The same page also showed one bottle at a $64.99 sale price. The secure order page shows the final price before you pay, so go by that number.
How much does Mighty K9 cost per day?
At $89.99 a bottle, Mighty K9 costs about $3.00 a day. One bottle holds 30 servings of 2 mL, and the label says one serving a day, so a bottle lasts 30 days for one dog. At the $64.99 sale price, the daily cost drops to about $2.17.
Is the 6-bottle pack of Mighty K9 cheaper per bottle?
No. The 6-bottle pack is $539.94, which is $89.99 a bottle, the same as the 1 and 3-bottle packs. The only difference is shipping: packs over $100 ship free in the U.S. Choose a pack by how many months you want to cover, not by a discount.
Does Mighty K9 offer free shipping?
Yes, the sales page lists free U.S. shipping on orders over $100. That covers the 3-bottle pack at $269.97 and the 6-bottle pack at $539.94. A single bottle is under $100, so its shipping cost is added and shown at checkout before you pay.
Does Mighty K9 have a subscribe and save option?
The sales page shows a Subscribe and Save option, but its terms are not explained there. We could not confirm the discount, the delivery schedule or how to cancel. Read the terms at checkout before you choose it, or buy a one-time pack if you want no repeat charges.
How many bottles of Mighty K9 should I buy first?
The sales page suggests starting with at least three bottles, which last about 90 days for one dog. It also says full results come at weeks 8 to 12, which is a brand claim. One bottle lasts 30 days and matches the 30-day money-back window, so it is the lower-risk first order.
