Mighty K9 Price: What Each Pack Costs and Which One to Pick

The 3-bottle pack is $269.97 and the 6-bottle pack is $539.94, both $89.99 a bottle with free U.S. shipping, about $3.00 a day.

How much does Mighty K9 cost?
A single bottle of Mighty K9 costs $64.99 on the brand store, and standard U.S. shipping adds $8, for $72.99 in total. The 3-bottle and 6-bottle packs list $89.99 per bottle and ship free.
Those are the prices the brand store showed on October 11, 2026 (Mighty-K9, product page). Before you pay, the order page gives the final total.
Each 60 mL bottle holds 30 servings of 2 mL, so the price of a bottle is the price of one month.
The honest part
Most supplement sites push the biggest pack. At these listed prices, the bigger packs cost more per bottle than the single bottle. We would rather you know that before you order.
The three packs
Which Mighty K9 packs can you buy?

Read before you pick
Why do the bigger Mighty K9 packs cost more per bottle?
The single bottle carries a sale price of $64.99, while the 3- and 6-bottle packs are listed at $89.99 a bottle. That is why the packs come out higher per bottle, even with free shipping.
Put plainly: Three single bottles bought one at a time cost $72.99 each with shipping. That is still below the $89.99 per bottle in the 3-pack. The packs give you fewer orders to place and free shipping, not a lower price.
- Single bottle: $64.99, plus $8 shipping, $72.99 in total.
- 3-bottle pack: $269.97, shipping free, $89.99 a bottle.
- 6-bottle pack: $539.94, shipping free, $89.99 a bottle.
- Free standard shipping applies to orders over $100 or with 3 or more bottles (Mighty-K9, shipping policy).
If the single-bottle sale ends, the math may flip, so compare the per-bottle number on the day you buy.
Subscribe and Save
Does Mighty K9 have a subscription discount?
Yes. The brand store shows a Subscribe and Save option at 10% off. A subscription sends a new bottle on a schedule so you do not run out.
Sign up only once you know your dog does well on it. Check three things first:
How often it ships
One bottle lasts 30 days at 2 mL a day. Pick a schedule that matches, so bottles do not pile up in the cupboard.
How to pause or cancel
Write down how to stop the subscription before you start it. Keep the confirmation email with your order ID.
The real total
Look at the price after the 10% comes off, plus any shipping. Compare it with a single bottle at $64.99 before you commit.

Order nowHow to choose
Which Mighty K9 pack should I buy for my dog?
Start with one bottle. It covers the full 30-day money-back window, costs the least per bottle at today's prices, and tells you whether your dog will even eat it.
Buy a longer supply only if your dog does well. That means your dog takes it with food, has no upset stomach or loose stool, and you have notes from the first weeks. The sales FAQ says owners often notice changes in two to three weeks, and that full results typically arrive between weeks eight and twelve. That claim has no dog trial behind it, so judge by what you see.
Most dogs
1 bottle
A first try. Thirty days, inside the refund window, at the lowest listed price per bottle.
If it suits your dog
3 bottles
About three months. Fewer orders and free shipping, at a higher price per bottle.
Only if sure
6 bottles
About six months in one order. Spares need a cool, dark cupboard, since C60 in olive oil breaks down in light (Grohn et al., 2021).
Supply planner
How many bottles of Mighty K9 do I need?
You need one bottle per month per dog at the label serving. Slide the planner to the number of months you want, and it shows the lowest-cost mix of orders at the listed prices.
For 30 days you need 1 bottle. Lowest total: 1-bottle order for $72.99.
Counts each order separately, with $8 shipping on a single bottle and free shipping on 3 or 6. A planning aid only; the order page has the final total.
Remember that a refund only covers the 30-day window. Buying six months up front means more money at risk if your dog stops eating it or gets an upset stomach. The guarantee page explains how a claim works, and shipping covers delivery times.
Context
Is Mighty K9 expensive compared with other dog joint options?
Mighty K9 sits at the higher end for a daily dog supplement, and it pays for a different thing than most joint products. You are paying for C60 in olive oil, which has no controlled trial in dogs (Hui et al., 2023).
We do not list prices for other products. Instead, think about where your money buys the best evidence:
- Keeping your dog lean costs little and has the strongest dog data. Lean-fed Labradors showed hip arthritis on X-ray at a median of 12 years, against 6 years for their heavier littermates (Smith et al., 2006).
- Omega-3 fish oil diets have controlled dog trials. In one, 82% of dogs improved in weight bearing, compared with 38% of controls (Roush et al., 2010).
- Glucosamine and chondroitin are often cheaper, yet showed no pain-relief effect in 88.9% of trials in one review (Barbeau-Gregoire et al., 2022).
If you add Mighty K9, treat it as an extra on top of weight control and vet care, not a swap for them. See how to choose a dog joint supplement for a fuller comparison.
