Glucosamine is a natural amino sugar that the body uses for forming and regenerating joint cartilage. In dogs and cats, it is often used as a supplement to reduce joint pain and stiffness and to slow the progression of osteoarthritis.
Does your dog have a growing body, or is it already a senior with a stiffer gait? Below, we explain what glucosamine is, how it works, and how to choose it correctly.
What is Glucosamine?
Glucosamine is an amino sugar that an animal’s body synthesizes naturally. It participates in the formation of glycosaminoglycans - a raw material for cartilage growth and regeneration.
With age, the natural production of glucosamine decreases. This can lead to cartilage damage, joint pain, swelling, stiffness, and lameness. Osteoarthritis in dogs and cats is a chronic disease - in its treatment, alongside medication, the use of glucosamine supplements is often an integral part of therapy.
How Does Glucosamine Help Joints?
Glucosamine acts as a natural anti-inflammatory agent that:
- relieves pain and reduces swelling;
- reduces joint stiffness;
- helps maintain cartilage structure.
In combination with chondroitin, glucosamine inhibits the activity of enzymes that break down joint cartilage.
Which Dogs and Cats Need It?
Glucosamine can be beneficial for:
- growing, large dogs whose joints are subjected to greater stress;
- seniors with joint stiffness or osteoarthritis;
- cats with age-related joint problems;
- animals after joint injuries or surgeries.
In cats, joint pain often goes unnoticed - they hide discomfort, which manifests as reduced activity, reluctance to jump, or altered behavior. If you notice this, it’s worth discussing it with a veterinarian.
How to Choose a Glucosamine Supplement?
When choosing a product, pay attention to the composition of active ingredients:
- how high the glucosamine concentration is;
- whether additional active ingredients are included - for example, chondroitin or MSM (methylsulfonylmethane).
The best source of glucosamine is glucosamine derived from shellfish or shrimp shells (in the form of glucosamine hydrochloride or sulfate). Tablets, powder, solution, and chewable forms are available.
Suitable glucosamine supplements for dogs and cats can be purchased at our veterinary pharmacy and pet store →.
How and How Much to Give? When to Expect Results?
The dosage is determined by the animal’s weight and the specific product - always follow the manufacturer’s instructions or your veterinarian’s recommendation. Initial doses are recommended to be given with food.
Glucosamine does not work immediately - improvement can usually be noticed after 4-6 weeks of regular use. In cases of chronic joint problems, it is often used long-term.
Are There Side Effects?
At the beginning of use, puppies and kittens may experience diarrhea or bloating - therefore, it is important to give the initial doses with food. If symptoms persist, consult your veterinarian.
