Best Glucosamine for Dogs: Can Canine Joint Supplements Help Ease My Dog's Joint Pain?

Why Should I Put My Dog on a Glucosamine Supplement?

As dog owners, we want to know what supplements can help our pups feel their best regardless of age. Glucosamine is a supplement that can support healthy joints for our dogs. This is especially important as our dogs age and their joints begin to wear down.

Hip dysplasia and arthritis are common hip and joint problems that can develop in dogs, and there are many supplements available that are easy to administer to your dog that can coat the joints and provide pain relief for these bone conditions. With so many options to choose from, it can be a struggle to choose the best glucosamine for dogs. In the sections below, we will explain what joint conditions commonly affect dogs, how glucosamine can help, and which supplements we recommend for dog owners.

Glucosamine is a beneficial supplement for many dogs with varying ages and medical conditions. Due to improvements in veterinary care and dog owner education, domestic dogs are living longer. As dogs age, their bones and joints deteriorate while the muscles around them become inflamed. This can be very painful for dogs.

Fortunately, glucosamine supplements combined with chondroitin work to coat the joints, relieve pain, and reduce inflammation around problem areas.

When considering adding glucosamine to your dog's diet, it is important to find one that also includes chondroitin to help any inflammation your dog may be experiencing.

3 Main Arthritis Symptoms to Watch For in Your Dog

Arthritis is a problem that many pet owners will face as their dog ages, and Arthritis has several warning signs associated with it. As a pet owner, if know what to watch for, you may be able to get your dog on a supplement sooner which may help to alleviate the damage Arthritis can do to your dog's joints.

Warning Sign One: Difficulty Moving
Perhaps you've noticed your dog having difficulty getting up or down stairs, or simply standing up. This is one of the easiest arthritis warning signs you'll get as a pet owner, and it's relatively easy to track.

Many dog breeds tend to develop arthritis in their backs, hips, legs, shoulders, and joints as they age. Your dog may seem more hesitant to jump up on things, have less flexibility, and trouble with sitting or going from laying down to standing.

Once you do notice these symptoms, you should also take note if your dog's mobility problems are worsening or staying the same. By watching your dog, you should get a good idea of how much they're feeling this common Arthritis symptom.

Warning Sign Two: Muscle Tone Changes
When it hurts your dog to move around like they used to, they might spend a lot more of their time laying or sitting down. This decreased activity level can have a negative impact on your dog's overall muscle tone.

If your dog's muscles aren't getting used on a regular basis, you may see a softening of their muscle tone. Your dog may seem weaker, and their leg and thigh area muscles will look and feel softer to the touch.

Unfortunately, this lack of movement can also lead to an increased weight gain as your dog isn't moving around and burning off as many calories. If you combine this with a softening muscle tone, you could quickly see your dog's quality of life go down.

Warning Sign Three: Increased Pain Levels
While it isn't unusual for older dogs to experience some minor aches and pains, high levels of pain will most likely be easy to recognize. Your dog may begin to favor one leg over the other and develop a limp if their joints or hips hurt when they walk.

Once your dog starts limping, pay closer attention and observe them throughout the day. You'll most likely see your dog experiencing higher pain and stiffness levels in the morning hours, and this is a common time of day for this symptom.

These increased pain levels can also lead to your dog having a significant decrease in their willingness to play or run around. They do this because they're trying to avoid the pain that can come with arthritis, and it may be a gradual change that can take weeks to notice.

What are Glucosamine and Chondroitin and How Do They Help My Dog?

Common Areas of Joint Pain in Dogs

Glucosamine and Chondroitin are two key ingredients in almost all dog joint health and arthritis prevention and reduction supplements. They each have benefits for your dog on their own, but when you combine them together, you can get a more powerful overall formula that can help to reduce your dog's arthritis symptoms.

Glucosamine is a naturally-occurring compound that is found in your dog's system, and it one of the more popular joint supplement ingredients you hear about. It helps to reduce any previous damage done to your dog's joints by injury or arthritis, and it helps to strengthen the cartilage that is there.

As your dog ages, their natural Glucosamine production slows down, and this is one of the factors that can lead to an increased wear and tear on the joints. Along with this, your dog's cartilage cells are always renewing, and damage can lead to inflammation and the cells releasing enzymes which can lead to even more joint damage.

A joint supplement can help to restore your dog's Glucosamine levels and give your dog's immune system a boost. Also, Glucosamine has several other benefits including:

  • Ease the recovery process due to joint surgery
  • Keep working and performance dogs in top condition
  • Rebuilds and restores joint cartilage
  • Helps improve joint flexibility and lubrication for easier movement
  • Helps to cushion your dog's joints so they have reduced pain levels

The second key ingredient in many dog joint supplements is the compound called Chondroitin. Chondroitin is also considered to be a natural compound, and you can find it in your dog's cartilage.

The main function of this naturally-occurring compound is to help your dog retain water in their cartilage, and this helps the joints retain their elasticity, and it provides shock absorption from everyday activities. Additionally, it helps to nourish your dog's joints and cartilage, so they remain healthy and balanced.

As your dog ages, it isn't unusual for them to produce less and less Chondroitin. When this happens, your dog may start to experience less flexibility and more stiffness at the joint level, increased pain, and inflammation.

By giving your dog a joint supplement that contains Chondroitin or a mix of Glucosamine and Chondroitin, you may see several benefits including:

  • Decrease in inflammation and swelling
  • Improved flexibility levels
  • Hydrates the joint cartilage for better shock absorption
  • Protects existing cartilage from further damage
  • Assists with preventing any stress injuries due to damaged ligaments

When you combine both of these ingredients, they can work off of one another and improve their effectiveness. You may also get a more complete joint repair and protection package if you choose a joint supplement with both of these ingredients instead of one or the other.

What is the Recommended Glucosamine Dosage for Dogs?

Before you begin to give your dog any new supplement, it is a good idea to consult with your veterinarian and see if they recommend that you start your dog on this supplement. It is also important to note that the amount of Glucosamine you give your dog can and usually will vary from dog to dog depending on their age, weight, and other health factors.

When you choose the Glucosamine supplement you want to use, and your veterinarian has given you the okay to use it, carefully check the dosage instructions. It is not uncommon for different brands of Glucosamine supplements to have different dosing amounts and instructions.

Additionally, you have to consider if the Glucosamine product instructs you to give your dog a loading dose or not, as this can easily lead you to give them too much or too little right from the start. Many supplements recommend that pet parents give their dog either one and a half or two times the normal amount for a short period of time to jump-start the supplement's beneficial effects.

It is possible to overdose your dog with Glucosamine, and this is why it is extremely important you talk to your veterinarian and carefully follow any and all dosing instructions they give you, or you get with the supplement. If you believe you've given your dog too much Glucosamine, your dog may exhibit the symptoms we've listed below, and you should call your veterinarian right away.

  • Vomiting
  • Lethargy
  • Skeletal structure and joint pain increase
  • Jaundice (eye yellowing)
  • Increased thirst and urination

When you begin giving your dog the Glucosamine supplement, make sure your dog's treats don't also contain Glucosamine as this can lead to you accidentally giving them more than the prescribed dose. Other medications your dog may be on can also interfere with the dosage and the overall effectiveness of the Glucosamine supplement.

As with any new diet changes or supplements, it is important that you monitor your dog for any unusual behaviors or changes. If you notice something, it is a good idea to call your veterinarian and ask what they recommend you do.

What are the Differences Between Human and Dog Glucosamine?

Many pet owners assume that there are no differences between human and animal glucosamine. While glucosamine is an amino sugar that both humans and dogs have in their bodies, giving your pet the human version of this supplement could be a mistake that can lead to some harmful side effects for your pet.

Let’s go over the differences in the two types of glucosamine and how they differ for the human and dog systems.

Ingredients

Glucosamine itself is safe for both humans and dogs. What makes them different is the other ingredients that, while maybe healthy for a human, are not as healthy for your four-legged friend. In fact, some of these ingredients can even be fatal for dogs.

The Coating

Another factor that makes a difference is the coating in the supplement tablets. The coating on human supplements is designed to digest in the human digestive tract, not that of a dog. While our systems can process the coating easily and without any issues, your pet's system may have difficulties and could lead to health issues.

Digestive System

There is another difference between canine and human versions of glucosamine. Each digestive systems works in different ways when breaking down materials.

Since our digestive tract is much longer than that of a canine, it has plenty of time to be absorbed before passing from our bodies.

If your dog was to take a human tablet designed to be swallowed whole, the tablet would more than likely pass through their system long before it has time to properly dissolve.

This is why canine glucosamine tablets are designed to be chewed, it helps to break down the material and allows it to be absorbed into their bodies.

Unless you are planning on giving your dog a human supplement that is pure glucosamine, such as a powder or liquid, your best bet is to simply purchase a glucosamine supplement designed for canines.

Side Effects of Glucosamine for Dogs

The side effects that can occur from your dog taking a Glucosamine supplement have been reported as being a rare occurrence. As a pet parent, you should also know that the side effects that do present are typically very mild and resolve on their own once your dog's system has time to regulate to the new supplement.

Allergic Reactions
If your dog has an allergy to shellfish, double check the ingredients in the Glucosamine supplement, as many of them have a shellfish base. It is possible to find corn or plant-based supplements that contain Glucosamine, but they're slightly more difficult to find.

A common mild symptom of an allergic reaction is your dog chewing or biting at his or her feet. If your dog has a strong shellfish allergy, it could send them into anaphylactic shock, and they'll need immediate veterinary treatment.

Diabetic Problems and Blood Sugar Interactions
If your dog is on medication for common conditions like Diabetes, it is generally not a good idea to give them a Glucosamine supplement as this can interfere with how well their diabetes medication works. Again, if you're not sure you can always ask your veterinarian how the two would mix, or if it would cause further problems.

Your veterinarian may recommend a lower dose than the instructions say to use, or they may recommend that you avoid giving your dog the Glucosamine supplement entirely.

Gastrointestinal Issues
Some of the most common issues pet parents have reported after starting their dog on a Glucosamine supplement is mild gastrointestinal issues like runny stool, vomiting, and general upset stomach. These symptoms typically go away on their own as your dog's system gets used to the supplement.

You can also check the instructions and see if they recommend you give your dog food when you give them this supplement. It can be beneficial to give your dog's stomach a cushion of food before you give them the supplement so it can absorb quickly and not be so harsh on their system.

Liver or Kidney Problems
If your dog has liver problems, liver disease, kidney problems, or kidney disease, adding a Glucosamine supplement is generally not recommended for safety reasons. Your dog's body won't be able to filter out and regulate the Glucosamine, and it can actually cause more damage to your dog's liver and kidneys.

Even at extremely low doses, Glucosamine may cause liver or kidney failure if your dog has existing problems, and you don't want to make your dog's condition worse.

Which Joint Supplement Works for Dogs with Food Allergies?

Every year, thousands of dog owners make the decision to start their aging dogs on a joint supplement regimen. However, dogs have food allergies just like humans do, and this can make something as simple as adding a supplement much more complicated.

Remember, the overall health of your dog and any other conditions will affect the way they respond to supplements. Always check with your veterinarian before adding supplements to your dog's diet.

Food Allergies and Supplements

One topic that can put a halt on your search for a good supplement is food allergies. Dogs who have food allergies or sensitivities need special care when the time comes to add in supplements like glucosamine. So many supplements have added ingredients which, even in small amounts, can trigger a reaction in your dog.

Vegetarian glucosamine is a viable option for dogs with food allergies, especially shellfish allergies. Since shellfish is the most common source of glucosamine, a shellfish allergy severely limits the safe options for your dog. The glucosamine in vegetarian supplements is derived from corn. These supplements now also included MSM derived from plants, where older vegetarian supplements were missing this ingredient.

This article describes a great option for dog owners who have to consider food allergies when choosing a high quality joint supplement.
