How much do you give a 20lb dog? How long will it last?

Thank you for your question! The manufacturer's recommended dose range for concentrated 90g formulas is 0.125-0.25g per 10-20lb twice daily for dogs and cats. The length of time the bottle will last depends on the dose your vet recommends in that range. If you find out how many grams per day your vet recommends, you can figure out how long it will last. You can divide 90 by the number of grams per day your vet recommends to see how many days the bottle will last.
