As dogs age, it's common for their joints to start causing them pain and discomfort. Just like in humans, arthritis is a frequent cause of lameness and stiffness in older dogs. Fortunately, there are several joint supplements that can help ease these symptoms and support continued joint health. In this article, we’ll explore the science behind joint supplements for dogs, discuss which ones are most effective, and provide recipes for incorporating supplements into tasty homemade dog treats.
The Aging Canine Skeletal System
To understand joint supplements, it helps to first review some basics about how a dog's joints work. A joint forms wherever two or more bones meet. The ends of the bones are covered in smooth cartilage, protecting the bone surfaces and allowing them to slide past each other with minimal friction. The entire joint is enclosed in a capsule lined with synovial membrane, which secretes synovial fluid that lubricates the joint space.
Ligaments connect bones together and provide stability to the joint. Tendons attach muscles to bones, allowing the muscles to move the joint through contraction. The surrounding muscles, tendons, and ligaments provide dynamic support to help stabilize the joint through its full range of motion.
As dogs age, their joints undergo several changes that can impede optimal function:
- Cartilage breakdown - Years of use and minor injuries take their toll on the slick cartilage lining the ends of bones. As cartilage deteriorates, more stress is placed directly on the bone endings.
- Reduced synovial fluid - The synovial membrane produces less joint lubricant over time. This reduces smooth joint gliding and can allow painful bone-on-bone friction.
- Ligament laxity - Ligaments stretch out gradually with age, leading to joint instability and decreased proprioception (sense of body position).
- Muscle atrophy - Disuse, pain, and age-related muscle loss lead to thinner, weaker supporting muscles around affected joints.
- Bone changes - The bones themselves may develop abnormal bony growths, fragments, and cysts.
These age-related changes reduce shock absorption and smooth motion in the joints. The resulting pain, stiffness, instability, and inflammation are collectively referred to as degenerative joint disease or osteoarthritis.
Common Joint Issues in Senior Dogs
Though osteoarthritis can happen in any joint, several locations are especially prone to problems in aging dogs:
- Hips - Hip dysplasia and osteoarthritis are very common, particularly in larger breeds.
- Knees - Cruciate ligament tears lead to instability, wear and tear.
- Elbows - Elbow dysplasia and fragmented medial coronoid process (FCP) cause osteoarthritis.
- Shoulders - Rotator cuff injury and osteoarthritis cause lameness.
- Spine - Intervertebral disc disease and spinal arthritis result in back pain.
No matter the location, the goals of treatment are the same - reduce pain and inflammation, protect remaining cartilage, improve joint mobility, and increase comfort during activity. Let's look at how joint supplements can help achieve these goals.
The Science Behind Joint Supplements for Dogs
Several compounds found naturally in healthy joints and cartilage have been extensively studied for their benefits in dogs with arthritis.
Two main categories show particular promise:
- Glucosamine and Chondroitin Sulfate
Glucosamine and chondroitin are structural components of cartilage and synovial fluid. Supplementing them is thought to help repair and maintain cartilage while also decreasing inflammation.
Multiple scientific studies show reduced arthritis symptoms and improved mobility in dogs receiving these supplements, particularly when combined.
Benefits often take 4-8 weeks to see and may include:
- Decreased pain and lameness
- Increased weight-bearing and activity level
- Improved range of motion in affected joints
- Less need for anti-inflammatory prescription medications
Glucosamine and chondroitin have an excellent safety profile with minimal side effects. They may also help slow the progression of osteoarthritis.
- Omega-3 Fatty Acids
Omega-3s like EPA and DHA from fish oil sources have powerful anti-inflammatory effects. They inhibit the body’s natural inflammatory response to joint damage and arthritis.
Studies in dogs confirm reduced inflammation and improved mobility and pain scores when taking omega-3 supplements.
Additional benefits may include:
- Decreased stiffness after long periods of rest
- Ability to lower prescription anti-inflammatory dosages
- Improvements in itchy skin/allergies due to omega-3’s effects on the immune system
Omega-3 fatty acids are extremely safe for dogs. Look for a quality fish oil product derived from wild-caught fish sources. The optimal EPA to DHA ratio is around 5:1.
Other Joint Supplements for Dogs
A few other compounds show promise for canine joint health, though more research is needed:
- MSM (methylsulfonylmethane) - This sulfur-containing molecule may have anti-inflammatory and analgesic effects.
- Curcumin - Found in turmeric, curcumin has been studied for its anti-inflammatory properties. Absorption is a challenge.
- Green lipped mussel - This New Zealand shellfish contains glycosaminoglycans and omega-3’s that may support joints.
- Hyaluronic acid - Directly supplements the synovial fluid that lubricates joints. Also used intravenously.
- SAMe (S-adenosylmethionine) - Synthetic form of a natural compound involved in cartilage synthesis.
- Collagen - May support cartilage and connective tissue repair. Collagen peptides are easily absorbed.
- Avocado/soybean unsaponifiables (ASU) - Plant-derived extracts with anti-inflammatory effects.
- Boswellia - Herbal medicine used for centuries to treat joint pain and inflammation.
How to Choose the Best Joint Supplements
With so many products available, choosing the right joint supplements for your dog can feel overwhelming.
Follow these tips for finding effective products:
- Consider your dog's size/breed. Some ingredients work better for larger versus smaller dogs.
- Look for clinical studies proving efficacy and safety, especially in dogs.
- Choose reputable brands that follow Good Manufacturing Practices (GMP).
- Verify if the product has received an NASC (National Animal Supplement Council) seal. This ensures quality standards.
- Avoid artificial preservatives, colors, sweeteners, and fillers in supplements.
- Review labels for dosing. Amounts and frequencies vary between ingredients.
- Talk to your veterinarian, especially if your dog takes any medications or has other health conditions.
Incorporating Supplements in Homemade Dog Treats
Rather than giving joint supplements as capsules or tablets, another option is incorporating some of the key ingredients into homemade dog treats or food.
Some easy ways to do this include:
- Mixing glucosamine/chondroitin powder into peanut butter or pumpkin and stuffing in a Kong toy. Freeze for a cool, long-lasting chew treat!
- Adding fish, krill, or algae oil to homemade dog food recipes as a source of omega-3s. Salmon oil works great drizzled over kibble.
- Including collagen peptides powder when making homemade dog biscuits or cookies.
- Using bone broth made with the bones/cartilage of chicken, beef, or fish as the liquid in homemade food or as a base for gravy to pour over kibble.
- Making turmeric paste with ground turmeric and oil to mix into homemade treats. Black pepper increases curcumin absorption.
- Adding green lipped mussel powder into homemade jerky or dehydrated sweet potato treats.
- Using avocado or peanut oil as healthy binding fats when baking dog treats - both provide additional joint support!
Start with small amounts of new supplements to ensure they agree with your dog's stomach. It’s also smart to consult your vet before significantly altering your pup’s diet.
Tips for Cooking with Joint Supplements:
- Glucosamine/chondroitin powders tolerate heat well. Add before baking homemade treats.
- Collagen peptides dissolve well in warm liquids if adding to homemade wet dog food.
- Fish oil can get rancid with heat. Drizzle over treats after baking or just before serving instead.
- Turmeric paste mixes best into room temp wet food rather than baked treats.
With delicious homemade treats like these, your dog will have no problem getting their joint supplements in their diet! Just remember to always follow dosage recommendations for any ingredients you add.
The Outlook for Dogs on Joint Supplements
Research clearly shows that supplements like glucosamine, chondroitin, and omega-3’s can provide real benefits to dogs suffering from painful osteoarthritis and other joint problems. They’re an excellent complement to prescription anti-inflammatories, joint injections, physiotherapy, and other treatments recommended by your veterinarian.
While no cure for arthritis exists, supporting joint health can keep your senior dog active and comfortable for as long as possible. Be patient, as it may take weeks to months to see improvements, and consider combining several synergistic joint supplements together.
