What's the Right Glucosamine Dosage for Dogs

Glucosamine is a drug that is recommended for dogs that have problems with arthritis.  If a dog no longer enjoys moving around, is lethargic, limps and/or shows signs of pain when touched, then this may mean that the dog has a problem with arthritis.  Arthritis is a prevalent problem with dogs that are getting on in years; thankfully, glucosamine combats this problem by helping to build up a dog’s cartilage so that it can once again enjoy life and moving around.

There are various factors to consider when purchasing glucosamine for dogs.  First of all, one should take the dog to a vet and ask the vet if the dog should have sulfate, HCL or 2KCL glucosamine.  When purchasing glucosamine, it is important to ascertain that the drug is superior quality and has been made in a GMP certified facility.  Low quality glucosamine is not as effective as it needs to be, as many dog owners have discovered.  Liquid glucosamine is easier to administer to dogs that tablets, as it tastes good and a dog will readily drink it.

Correct Glucosamine Dosage for Dogs

Administering the right glucosamine dosage for dogs is imperative.  A dog that does not get enough of this drug will not show visible improvement.  However, there is a dosage limit and a conscientious pet owner should never give a dog an overdose of glucosamine.

First of all, one will want to talk with a vet about the dog’s glucosamine dosage.  A vet will be able to give one a recommendation of how many fluid ounces a dog should have per day and how many times per day the medication should be given.  The dosage is determined by the dog’s weight; the heaver the dog is, the more medication it will need.

However, the dosage also depends on what type of glucosamine is being administered.  The type given should also be determined by a vet; in fact, if the dog is very sick then getting a second option from another vet may be advisable.  Most vets will recommend that a dog take a double dosage of this drug for the first four to six weeks.  After this time, a dog should show visible improvement and be able to take less glucosamine.


A dog owner should realize that glucosamine is not an instantly effective wonder drug.  In fact, it takes at least two weeks to a month before a dog will show visible signs of improvement.  However, if the dog is not better after a month, it could be a sign that the original dosage prescription is too low, or that a dog also needs anti-inflammatory medication with the glucosamine dosage.

The right glucosamine dosage for dogs depends on various factors.  The main factor is the dog’s weight.  Generally speaking, a dog that weighs under 10 lbs. should only take 300 mg of glucosamine daily; dogs that weigh from 11-29 lbs. should have twice this much.  Dogs that weigh from 30-59 lbs. should have 1200 mg of glucosamine daily, and dogs that weigh from 60-120 lbs. should have a dosage of 1800 mg.  However, consulting a vet is always in order, as only a vet will be able to make a fully accurate prescription for the amount and type of glucosamine that should be used.
