What CBD for Dogs Really Costs Per Month
Nobody puts the monthly number on the label, so here it is. The real cost of CBD depends on three things: your dog’s weight, the strength of the oil, and whether you are in the loading week or on the maintenance amount. Below is the honest math at our current prices, and the method works for any brand’s bottle.
Quick answer
At maintenance dosing, quality broad-spectrum CBD runs from roughly $18 per month for a 10 lb dog to roughly $118 per month for a 100 lb dog at our current prices. The first week costs more because the loading dose is about double. Compare products on price per milligram of CBD – not bottle price – and right-size the bottle strength to the dog.
Monthly cost by dog size (maintenance dosing)
Maintenance is about 1 mg/kg per dose, twice daily. These numbers use the best-fit Rejuvenator bottle at current prices; the pattern (bigger dog, bigger bottle, lower cost per milligram) holds for any honest brand.
| Dog weight | Daily amount | Best-fit bottle | One bottle lasts | Cost per month |
|---|---|---|---|---|
| 10 lb | about 9 mg | Small (750 mg, $49.99) | about 83 days | about $18 |
| 20 lb | about 18 mg | Small (750 mg, $49.99) | about 41 days | about $36 |
| 30 lb | about 27 mg | Medium (1,500 mg, $79.99) | about 55 days | about $44 |
| 50 lb | about 45 mg | Large (3,000 mg, $129.99) | about 66 days | about $59 |
| 75 lb | about 68 mg | Large (3,000 mg, $129.99) | about 44 days | about $88 |
| 100 lb | about 91 mg | Large (3,000 mg, $129.99) | about 33 days | about $118 |
Two notes on reading the table. First, the loading week (about 2 mg/kg per dose) roughly doubles the daily amount, so your first bottle goes faster than the table suggests. Second, notice the 50 lb row: the Large bottle costs more up front but comes out cheaper per month than running a Medium dry every month. Bottle size is a lever.

Why bottle price lies
A $30 bottle with 150 mg of CBD costs $0.20 per milligram. A $50 bottle with 750 mg costs $0.067. The “cheap” bottle is three times the price for what you are actually buying, and it will run out in days at a real dose. This one division – price divided by total milligrams – cuts through nearly all pet CBD marketing. Our calculator page has a true-cost checker that does it for any product in two fields.
Three honest ways to lower the cost
- Right-size the bottle. Larger bottles cost less per milligram – the Large works out to about $0.043/mg versus about $0.067/mg for the Small. If your dog is 45 lb or more, the bigger bottle is the cheaper bottle.
- Do not stay on the loading dose. After the first week, maintenance is about half the loading amount. Staying at the loading dose doubles your monthly cost without a reason.
- Subscribe if you are staying on it. CBD is a daily-use supplement judged over weeks, so if it earns its place, subscription pricing beats re-buying bottle by bottle.
What about cats?
Cat math is different: feline oils come in smaller bottles at gentler strengths, which costs more per milligram. At label dosing, a 10 lb cat uses about 1.4 ml per day, so a 30 ml bottle lasts about three weeks – roughly $56 per month at our current cat oil price. The calculator runs the exact numbers for your cat’s weight.

Frequently asked questions
How much does CBD oil for dogs cost per month?
At maintenance dosing with a quality broad-spectrum oil, roughly $18 per month for a 10 lb dog, about $44 for a 30 lb dog, and about $118 for a 100 lb dog at our current prices. The loading week costs about double.
Is more expensive CBD better?
Not by itself. Judge price per milligram, the COA, and whether it is THC-free broad spectrum. A high sticker price on a weak or unverified bottle is the worst of both worlds.
What is the cheapest safe way to give a dog CBD?
A properly tested oil in the largest bottle strength that fits your dog, dosed by weight at maintenance after the first week. Skipping the COA to save money is the one economy that is not worth it.
