Much like human beings, as dogs start getting older, their bones get weaker and many suffer from arthritis and other bone-related issues. For this reason, they start feeling weaker and witness problems in their joints, bones and hips which, in turn, reduce their mobility. Your dog is a major part of your life, and it is important that you take proper care of it. This is especially true for some breeds that can be labeled high maintenance as they need to be looked after very closely.

It can be traumatic for a dog to witness such events and can also reduce its lifespan. To help their beloved friends pull through, many people start their pets on a diet of glucosamine supplements or joint supplement for dogs to help them get better and live a long and fulfilling life.

Taking into account all the most important factors, we have selected Top 5 Glucosamine Supplements for Dogs


What Is Glucosamine and How Does It Work?

Let’s get one thing out of the way; dog glucosamine is different from that for humans. Do not try to feed your dog with human supplements. Glucosamine is sold in supplements and comes from an unusual source which is shellfish. The shells of these crustaceans are rich in amino sugar which is also present in bodies and has a key role in building and maintaining the cartilage (a layer of tissue that protects the bones from each other, especially in the joints).

Glucosamine can easily be produced in abundance by young dogs which ensures healthy bone development, but as dogs get older, the production decreases because the cartilage in their bones almost disappears. This can easily cause a condition known as osteoarthritis. The cartilage that is no longer there causes the bones in the joints to rub against each other, causing pain and inflammation and, thus, low mobility.

By adding the best glucosamine supplement for dogs in their diet, you can help bolster its supply in their bodies. This will help reduce the symptoms and problems being caused by osteoarthritis. As soon as the supplements are absorbed into the dog’s system, you can see the impact in a few weeks. It will give the pet a healthier cartilage, ensuring that the pain goes away and it gains more mobility.

If your dog is healthy, it is recommended that this supplement should not be given as it will be of no use and will come out from the other side. Some studies have also found that this ingredient helps some dogs with their hip dysplasia, though the results of these studies are still a bit inconclusive.

Another thing to note is that glucosamine is usually made with chondroitin sulfate, which is another nutrient that plays an essential role in curing osteoarthritic dogs. The way this works is that it combines enzymes that can actually cause damage to the cartilage and fluid.

If you feel that your dog might be suffering from any bone-related disease which usually comes with age, it is best that you take your dog to the vet and talk to them about the problem you might be facing. They will be able to determine whether the dog needs glucosamine or not and which type will be best suited for it to consume.

Benefits of Using Glucosamine for Your Dog

There are many reasons vets recommend that you give your dog glucosamine, especially since it is one of the safest dietary supplements that you can give to a dog. There are also many other benefits of these supplements, some of which are listed below:

Anti-Inflammatory Properties

More often than not, when a dog suffers from pain, especially joint or cartilage related, an inflammation occurs as the bones start rubbing together. This can increase the pain that a dog may feel and lower mobility further. Glucosamine also has anti-inflammatory properties, which ensure that the pain is reduced and there is no other problem caused by it.

Restores Joints

As the supplements increase the level of glucosamine present in the body, it aids in restoring the joints back to the way they were. This also helps it increase your pet’s mobility and activity level and the great part is that your dog will then be able to enjoy moving around again.

Formation of Connective Tissue

With more glucosamine present in the body, the cells are stimulated to work more due to which the connective tissues, especially the cartilage one which gets damaged during arthritis, are retired as their formation starts again.

Prevents Bone Decalcification

In this condition, bones start to get weaker, but with glucosamine for dogs, they stop deteriorating. Also, in the future, the ingredient prevents bone decalcification.

Protects Joints

Once a dog starts on this supplement, it ensures that the dog does not suffer anymore from damage and degeneration of the joints. It also protects the ligaments and regenerates both.

Strengthens Joints and Prevents Arthritis

Another great benefit that glucosamine provides your dog is that it ensures the protection and strengthening of the joints all over their bodies. The best part about glucosamine is that it helps dogs fight against arthritis, helping them resume some of their energy levels and allowing them to walk more comfortably and live a longer and healthier life.

Increases Mobility

One of the worst aspects of arthritis and other bone-related problems is that they decrease the activity and mobility of the dog. You will find a considerable difference in its walking and activity level once the effects of glucosamine start kicking in.

Helping the Cartilage

Remember how we mentioned that the cartilage of dogs are compromised when they hit old age? This supplement ensures that the articular cartilage of a dog is rebuilt.

Infrequent Side Effects

Unlike most supplements and other medicine, glucosamine rarely has any side effect. Even if it does, it is very minor. Even in the case of an overdose, you don’t have to worry as it won’t cause any functional problems in the dog.

How Can I Tell That My Dog Needs Glucosamine?

First of all, you must trust your instincts. When you feel your dog is getting old and having problems with its walk routine, take it to the vet for a checkup and talk to them about it. Some signs that you need to look out for include:

  1. Stiffness in your dog’s postures whether it sits, walks or otherwise
  2. Old age
  3. Decrease in its activity
  4. Signs of arthritis
  5. Wincing while walking or playing

As soon as you spot any one or more of these signs, go to your vet and discuss the forms of release available and what would be the best option or your dog. They will also help you decide the right dosage and form of glucosamine for dog’s arthritis. Also, sometimes vets might suggest you start on glucosamine just to make sure your dog remains healthy instead of suffering at a later stage.

Dosage of Glucosamine for Dogs

The best way to feed your dogs these supplements is by providing them as per the recommended dosage, which is usually administered according to their weight. You will mostly find the right dosage written on the bottle, but you can always ask your vet in the case you are unsure about it according to your dog’s size and weight. Yes, it is necessary to know the weight and size before you start giving it pills.

Usually, you will find that the recommended dosage is 20 mg of glucosamine per pound of the dog’s weight. Of course, it can also be different according to the severity of your dog’s condition. As they are present in various forms, pills, liquid, and powder, make sure you measure the right amount before you feed your dog. If it does not take it orally, try mixing it with its food.

Effects of Glucosamine Overdose

Glucosamine is thought to be one of the safest dietary supplements that you can give your dog. If it does not require too much glucosamine in its body, it is usually excreted out of the system. In case you do overdose your dog with glucosamine, there is nothing much to worry about as it will usually only cause a mild upset stomach and/or diarrhea. However, as these tablets are not licensed by the FDA, you need to make sure that you purchase them from quality manufacturers.

Another point to remember is that if your dog suffers from diabetes, you should avoid giving it these pills at all cost as they can block the formation of insulin. This can cause the sugar level to build up dangerously.

Side Effects of Using Glucosamine

There are minimal to almost no side effects of these pills, which makes glucosamine one of the best dog supplement. Some of the common side effects are:

  1. Fatigue
  2. Allergies (if your dog is allergic to shellfish)
  3. Thirst and urination
  4. Insomnia

If you feel that your dog is suffering from any of these, talk to your vet and/or stop giving the pills as they might not suit your pet.

What Form of Glucosamine Is Best for Your Dog?

As we mentioned earlier, there are various types of glucosamine available for consumption. You can find glucosamine for dogs as powder, liquid or even chewable pills. Your vet can tell best which form you should give your dog, but usually, it is recommended that you use the liquid form. This is because it is better for a dog since the absorption is quicker, making it more efficient, and the effects will kick in earlier. Hence, if you are unsure which type to go for, sticking to liquid glucosamine is the best way to go.
