Extend Joint Care for Dogs Review : We Asked A Vet

extend joint care for dogs
Did you know that 80% of dogs over the age of eight have arthritis? As a vet, I feel it’s my responsibility to address this with owners of senior pets. But it’s often difficult to make them understand that their healthy golden oldie might have something wrong with them.
As a result, I am usually met with resistance at the suggestion of medications but some openness towards starting supplements. There are so many supplements on the market, and I usually like to lay out the facts and let the owners decide on one, but today we are going to specifically look at Extend Joint Care for Dogs, and how it might help your dog.

So, what are the key features about Extend Joint Care for Dogs that sets it out from other joint supplements on the market? Here we will breakdown how the ingredients, benefits, and added extras set this product apart from the rest.

Glucosamine Hydrochloride:

This is an ingredient which provides a precursor for components which make up cartilage itself. Therefore, it can aid towards building up cartilage itself, thereby improving the gliding motion and shock absorbing ability of the joint. This then leads to improved mobility, range of motion and comfort of the joint.

MSM (Methylsulfonylmethane):

MSM lacks many scientific studies proving its use, but the few which have been published have been extremely positive indeed. MSM can decrease inflammation, improve energy levels, boost immunity and combat stress.
It is naturally found in green vegetables. The active component of MSM is the sulfur, which not only contributes to the previously listed benefits, but also helps to boost collagen production; a vital component of joint cartilage. Sulfur has also been shown to help reduce fluid build-up, which can be present when there are areas of swelling.

Type II Chicken Collagen:

This particular type of collagen is a natural product with many benefits. It is a natural source of chondroitin and hyaluronic acid, which promotes cartilage regeneration, and a thick, lubricating joint fluid. It helps improve the cartilage by retaining fluid in the connective tissue. Other than these benefits for joints, Type II Chicken Collagen can support the digestive system and boost the immune system.

Ascorbic Acid: This

This is an ingredient which many joint supplements do not contain. It helps to increase the production of glycosaminoglycans; the building blocks of cartilage, which in turn helps improve the cartilage and gliding action of the joint.
  • One size to fit all: This product is not specifically made for small, medium or large dogs, and therefore no matter what size your dog is, it will be suitable to use.
  • No negative drug interactions: There have been no recorded negative interactions with other medications, which is good as many dogs which need joint supplements will also be taking NSAID pain relief. In fact, it is often the case that by adding in a supplement, pain relief medications can be decreased.
  • No loading dose necessary: Extend claims that no loading dose is needed which means that it is much more affordable at the beginning compared to other products which need loading doses.
  • Only proven ingredients included: Whilst there have been no scientific studies looking at the effect of Extend Joint Care for Dogs specifically, there have been scientific studies looking at the efficacy of each individual ingredient.
  • Money back guarantee: A full money back guarantee is provided within 30 days, regardless of how much of the product you have used if you are not 100% happy with it.
  • Locally manufactured: Extend Joint Care for Dogs is manufactured in facilities in the USA which are registered with the FDA and USDA which adhere to strict quality assurance standards. After manufacture, each batch is then sent to an ISO accredited laboratory to be tested, which allows for a certificate of analysis to be produced for every batch.
  • Loss of joint cartilage: Throughout time, no matter how healthy a dog is, the joints will begin to degrade and the joint cartilage will become compromised. For some, this will just be a microscopic change, but for many, it will progress to active inflammation and osteoarthritis.
  • Developmental disorders: Dysplasia of the hip and elbow are the most common and the instability of the joint can lead to major discomfort. As discussed earlier, dysplasia can also lead to osteoarthritis if not addressed.
  • Injuries: If a bone becomes injured, it can cause an imbalance within the nearby joint which adds additional stress when that joint is loaded. Injuries to tendons and ligaments, such as a torn cruciate ligament, also lead to abnormal loading of joints, as the dog will be shifting the normal load of his weight away from the area which hurts.
  • Other causes of joint pain: Conditions such as hormone conditions, cancer, Lyme disease, and spinal disorders can indirectly afflict joints.

What's the best way to give it to my dog?

Extend Joint Care for Dogs is a powder which comes in sachets. It can be sprinkled over your dog’s food once daily, or mixed with water to create a meaty gravy. It is one sachet per dog per day, however if you have a teacup sized dog, then they may only need half a sachet, or if you have a giant dog, they may need more than one sachet.
The good news is that the product is extremely safe. Whilst there have been no reported side effects for Extend Joint Care for Dogs itself, there have been some reports of side effects for glucosamine alone. These include stomach upsets or increased frequency of urination. In addition, since glucosamine partly contains a sugar, some veterinarians are hesitant to give it to diabetic animals, however there is very little proof that this will affect their ability to regulate their blood sugar levels, especially if it is given at a meal time.
Not sold? Well fear not. There are also other products on the market which you can consider too. Here are three other alternatives:

Why would you buy a joint supplement?

Joint supplements are wonderful additives into your dog’s diet for many different reasons. As the name suggests, these joint supplements help care for your dog’s joints. But why would your dog need added extra help to keep their joints healthy? In the next section, we will look at when dogs require joint supplements, and these are usually cases when the joints are either being put through increased stress or the joint cartilage has become damaged.
The joint is made up of several components; the most important of which are the joint capsule, which contains the blood vessels which provide nutrients to the joint, the articular cartilage, the subchondral bone underneath the cartilage, and the synovial joint fluid. When a joint is sore or inflamed, the joint capsule doesn’t deliver as many nutrients to the joint, the joint fluid becomes thin and no longer acts as a good lubricant, and the cartilage and subchondral bone lose their ability to deal with concussive forces.
Therefore, if your dog either has joint problems, or is at a higher risk for joint problems, then a joint supplement will help maintain healthy joints through providing precursors for cartilage production, decreasing inflammation and improving the viscosity of the joint fluid.

When Do Dogs Require Joint Supplements?

There are many different scenarios where a dog will benefit from joint supplements, some of which are listed below:


Arthritis, also known as osteoarthritis, is a whole joint disease. It is when the joint begins to degenerate, and becomes extremely sore. The cartilage breaks down, and no longer provides a smooth gliding surface, and the joint fluid becomes thin and low in volume. As a result, the joint grates as it moves, causing considerable pain.
Arthritis does not simply happen in a healthy joint. The joint must either be unhealthy due to a poor conformation, dysplasia or trauma, or it must be subjected to repeat abnormal forces, for example sporting dogs. Therefore, there are lots of opportunities to act early to improve the health of the joint, if you know that your dog is at an increased risk of arthritis.
Once your dog has arthritis, joint supplements will help rebuild some of the damaged cartilage, and stop it degrading further, as well as improve the quality of the joint fluid. That way, the joint will glide more smoothly, which reduces pain and improves function.

Joint dysplasia

Hip and elbows are most commonly affected by joint dysplasia. When a dog has hip dysplasia, the head of the femur does not match the shape of the socket of the pelvis. As a result, the joint can become unstable and be subjected to abnormal forces. As earlier mentioned, this can then lead to arthritis.
Elbow dysplasia is a little different. When a dog has elbow dysplasia, it is usually because there is part of the joint which is meant to be stable has not fused properly. This means it moves around in the joint, and causes considerable pain and also leads to early onset arthritis if not surgically stabilized.
In both cases, joint supplements can slow down the progression of arthritis which otherwise will start early in life.

Large breed dog

Large breed dogs are susceptible to joint problems for two reasons. Firstly, large breed dogs are generally congenitally more prone to develop joint dysplasia. But even if they are lucky enough to have perfect joints, the increased gravitational weight on the joints over time will cause them to have to have excess strain on them over a lifetime.

Certain pure breed dogs

Some pure breed dogs are more likely to develop hip dysplasia, elbow dysplasia, a luxating patella or osteoarthritis. All of these eventually lead to joint degradation. As we’ve already mentioned, large breed dogs are more prone to joint dysplasia. In particular, Golden Retrievers, Labrador Retrievers, Rottweilers, Dobermans, Great Danes and Staffordshire Bull Terriers are most prone to joint dysplasia and subsequent osteoarthritis.
On the other hand, small terrier breeds, such as Jack Russells, Yorkshire Terriers and Miniature Schnauzers are more likely to develop luxating patellae, which can lead to osteoarthritis of the stifle.


When a joint is injured, the inflammation can set of a degrading cycle, causing the joint to have altered blood flow to it. As a result, the cartilage and the joint fluid suffer. In addition, weight is often shifted off of where it hurts, over to the other side, resulting in the contralateral joints to bear more weight and strain.

Certain medical conditions

Some medical conditions can cause insults to the joints. For examples Lyme Disease, joint infections, Leishmaniasis and Rheumatoid arthritis, all cause inflammation of the joints.
There are so many joint supplements out on the market, it may seem overwhelming to choose one. But here are some things to look out for to help you choose the best.
  • Type of Glucosamine : There are two types of glucosamine; glucosamine hydrochloride and glucosamine sulfate. The hydrochloride salt is slightly more expensive; however, it has been shown to have more bioavailability in dogs. This is really important because the higher the bioavailability, the more is absorbed, and therefore the better it works.
  • Ingredients: Most joint supplements are not simply just glucosamine. Common other ingredients are MSM, chondroitin sulfate, hyaluronic acid, omega oils and green lipped mussel. There is scientific evidence, albeit fairly weak, promoting the use of all of these in the management of joint issues, and therefore, looking for a product which contains multiple products may yield better results.
  • Reviews: Always check the reviews. It’s all well and good if a company says that it works, but they need results to back it up. Reading first hand reviews about how the product has helped real life pets, will help you choose one which truly works.
  • Price: The price of a supplement will directly reflect the quality of the ingredients. To ensure that you choose the one which contains ingredients which are both effective and ethically sourced, you should not look for the cheapest product on the market. The cheaper products may not contain pure ingredients, which risks exposing your dog to contaminants, or they may not contain any of the ingredients which they have stated at all!
  • Scientific studies: Joint supplements are not regulated, which means they do not have to prove that they work or conduct any research prior to putting them on the market. Some supplement companies, however, have gone above what is required of them and invested in proving the efficacy of their product. These supplements should not be overlooked, as they will be far superior to others on the market.
So, you’ve now searched around, and chosen a few joint supplements which you think you might want to try out on your dog, but you still aren’t completely sure how to make your final decision. Here are five tips to know before buying:
  • Loading dose :Many joint supplements will require a loading dose of double, or even triple, the normal dose to get it established in the system. This might be the required dose for anywhere between two and six weeks. The longer and higher the loading dose required; the more initial expense.
  • Certification :Joint supplements do not have to be certified with any organization, nor are they FDA regulated. But those which have sought additional certification, such as GMP certification or organic certification, can be more trusted for avoiding any unnecessary or harmful additional ingredients.
  • Guarantee :Not all products offer a money back guarantee, but many do. It is nice to know when a company is confident in their product that they will provide a guarantee if you don’t see a difference.
  • How it’s administered :Supplements can come in many different forms; capsules, tablets, treats, powder, syrup etc. Only you know which your dog will prefer the most, and so it is worth shopping around to find one which you can easily administer to your dog.
  • Who’s selling it? :Most joint supplements will be sold online, but by doing a bit of research, you may be able to find out whether reputable pet stores or veterinarians are also stocking and selling it. Those which are backed by professionals are more likely to be of a higher quality.


Now that you have learnt all about using joint supplements for joint issues, and specifically Extend Joint Care for Dogs, I’m sure you’re starting to contemplate starting your furry friend on something. Well, if he’s suffering from arthritis, joint dysplasia, an injury, or is simply a large or active dog, you have nothing to lose by trying out this supplement.
