PawBiotix costs $79, $69 or $49 per 30 mL bottle depending on the package, paid once with no autoship. What it costs per day depends entirely on your dog: the dose runs from 0.5 mL for small dogs to 2 mL for dogs over 76 lb, so the same bottle lasts anywhere from about 60 days to about 15. For a 30 lb dog the 6-bottle package works out to about $1.63 a day; for a 90 lb dog it is about $3.27.
What we like
- One-time payment; the FAQ says no autoship
- Weight-based dose, so small dogs cost little per day
- Free US shipping on 3 and 6 bottles
- 60-day guarantee that covers empty bottles
Keep in mind
- "60-day supply" only holds for a 26-50 lb dog
- Large dogs finish a bottle in about 15 days
- You pay return shipping

Most supplement price pages can stop at "cost per day". PawBiotix cannot, because the label doses by body weight: a Chihuahua and a Labrador on the same bottle are on very different budgets. So this page does the math per dog size. You will find the packages, the cost per milliliter, a cost-per-day table for each weight band, the shipping rules and how the 60-day guarantee fits in. For the strains, the evidence and which dogs should not take it, see our PawBiotix reviews and complaints.

| 6 bottles | about 180 days for a 26-50 lb dog | $49 | $294 | free US shipping + 3 e-books |
Prices as listed on the official order page when we checked (October 2026); the page presents the 3 and 6-bottle packages as "2 + 1" and "3 + 3". How long a bottle lasts depends on your dog's weight. The checkout page is the final word.
Payment is processed by BuyGoods, and the FAQ says there is no autoship and the checkout price is the only price you pay.
How long a bottle lasts for your dog
Each bottle holds 30 mL. The label sets the once-daily dose by weight:
| Dog's weight | Daily dose (label) | One 30 mL bottle lasts |
|---|---|---|
| 1 to 25 lb | 0.5 mL | about 60 days |
| 26 to 50 lb | 1 mL | about 30 days |
| 51 to 75 lb | 1.5 mL | about 20 days |
| 76 lb and up | 2 mL | about 15 days |
The order page's supply figures ("60-day supply" on two bottles) assume a 1 mL dose, which fits a 26 to 50 lb dog. For a 90 lb dog, six bottles last about three months, not six. Note too that the label says to refrigerate after opening and use within 6 months; at 0.5 mL a day, each bottle lasts about two months, well inside that.
Cost per day by dog size
Per milliliter, PawBiotix costs about $2.63 on the 2-bottle package (before shipping), $2.30 on the 3-bottle package and $1.63 on the 6-bottle package. Multiply by your dog's dose:
| Dog's weight (dose) | 2 bottles ($158) | 3 bottles ($207) | 6 bottles ($294) |
|---|---|---|---|
| 1-25 lb (0.5 mL) | about $1.32/day | about $1.15/day | about $0.82/day |
| 26-50 lb (1 mL) | about $2.63/day | about $2.30/day | about $1.63/day |
| 51-75 lb (1.5 mL) | about $3.95/day | about $3.45/day | about $2.45/day |
| 76 lb+ (2 mL) | about $5.27/day | about $4.60/day | about $3.27/day |
The 2-bottle figures exclude the $9.99 shipping, which adds roughly 5% to them. For a large dog, the 2-bottle package lasts only about 30 days and costs over $5 a day; that is the scenario where package choice matters most.

Is there a subscription or hidden charge?
No. The FAQ describes a one-off purchase with no autoship or recurring charges. Trial offers that convert to monthly billing are among the most common supplement complaints the FTC warns about; if a page offers PawBiotix as a trial or subscription, it is not the brand's offer. Check that the BuyGoods checkout total matches your package before you pay.
Shipping costs and delivery times
- 2 bottles: $9.99 shipping.
- 3 and 6 bottles: free US shipping.
- US delivery: 5 to 7 working days.
- Canada, the UK, Ireland, Australia and New Zealand: $15.95, 10 to 15 working days.
Plan reorders around those times, especially for a big dog who goes through a bottle in about two weeks.
The PawBiotix e-books
The 6-bottle package includes three e-books: The Ageless Dog, Brain Building Exercises for Dogs and Happy Dog Code. They are digital extras. Choose the package for the price per milliliter, not the reading.
Which PawBiotix package should you buy?
Small dog (up to 25 lb)
Two bottles already last about four months at 0.5 mL a day, longer than the 60-day guarantee. That makes the 2-bottle package a perfectly reasonable first order despite the higher per-bottle price; six bottles would be close to a year's supply.
Medium dog (26 to 50 lb)
This is the dog the brand's supply figures are built around. Two bottles cover the guarantee period exactly; three bottles give you 90 days at about $2.30 a day with free shipping. For a first try, the 3-bottle package is the balanced choice.
Large dog (51 lb and up)
At 1.5 to 2 mL a day, two bottles last only 20 to 30 days, so you would need to reorder before the guarantee ends. Three bottles cover 45 to 60 days, roughly the trial window, and six bottles cover about three months at the lowest daily cost. For a big dog, the 3-bottle package is the sensible minimum.
How the guarantee affects your choice

Every order from the official PawBiotix store is covered by a 60-day money-back guarantee, and it is a one-time payment with no subscription or auto-shipment.
The 60 days count from delivery, and the refund policy accepts all bottles, empty or not, which lowers the risk of a bigger order. You pay return shipping and need to include the packing slip. One caution: the refund page mentions both 60 and 180 days in different places. Plan around 60, and if you want more time, ask support in writing before you rely on it. Our guide to PawBiotix complaints and refunds has the steps.
Lower prices on other sites
The brand says PawBiotix is only sold on its own website, so a cheaper listing elsewhere is not covered by the guarantee. See where to buy PawBiotix for how to confirm the real store, and PawBiotix coupon codes for why codes will not beat the 6-bottle price.

Before you buy
The label says not to use PawBiotix in dogs with epilepsy or kidney or liver disease, in puppies or pregnant or nursing dogs, or in dogs on other medicines unless a veterinarian directs it. It contains beef liver and fish collagen, and kelp, a natural source of iodine. Diarrhea lasting more than a day or two, vomiting, blood in the stool or weight loss need a vet, not a probiotic.
