Verified Jun 17, 2026
A joint support soft chew supplement for small dogs and puppies that combines glucosamine, MSM, and type II collagen to help support healthy cartilage and joint function. It also includes boswellia for additional joint comfort, EPA and DHA from omega-3s, and astaxanthin as an antioxidant. This is designed to be a daily chew for dogs who need extra support for mobility, activity, or recovery from regular exercise.
This is a well-designed joint supplement for small dogs and puppies, with a thoughtful mix of glucosamine, MSM, collagen, boswellia, omega-3s, and astaxanthin to support overall joint health and comfort. The soft chew format is convenient for daily use and tends to be easy to give, especially for small breeds. It’s a solid option for dogs who are very active or starting to show mild stiffness and need added joint support alongside a complete diet.

At a Glance
KibbleLab Review
Strengths
- Multiple complementary joint-support ingredients (glucosamine, MSM, creatine, and type II collagen) that work together to support cartilage and overall joint function.
- Includes boswellia and astaxanthin, which can provide additional support for joint comfort and oxidative stress from activity or aging.
- Contains EPA and DHA omega-3 fatty acids, which are commonly used to support joint health in active or aging dogs.
- Soft chew format with small “mini” size is particularly suitable for small dogs and puppies that may struggle with larger tablets or chews.
Considerations
- Contains shellfish-derived glucosamine, so it may not be suitable for dogs with known shellfish allergies.
- This is a supplement, not a complete and balanced diet, so it should only be used in addition to an appropriate dog food, not as a primary source of nutrition.
- Includes cane molasses and starches for palatability and texture, which add a small amount of extra calories that should be considered if your dog is on strict weight control.

Top 5 Ingredients Explained
01
Glucosamine
Glucosamine is a dietary supplement commonly added to pet foods and treats to support joint health by promoting cartilage maintenance and repair and helping maintain joint function in dogs and cats. It can help reduce symptoms of osteoarthritis and improve mobility in older or large-breed animals, but effects are variable and may take weeks to appear; it is generally well tolerated though mild gastrointestinal upset can occur and many preparations are shellfish-derived (allergy and dosing, especially in diabetic pets, should be considered).
02
Methylsulfonylmethane
Methylsulfonylmethane (MSM) is an organic sulfur compound commonly included in joint-support supplements and pet foods as a source of sulfur for collagen and cartilage synthesis, and for its reported anti-inflammatory and connective-tissue support properties that may benefit mobility, skin, and coat health. It is generally well tolerated in dogs and cats and may help with joint comfort, but evidence is mixed and some animals can experience mild gastrointestinal upset or other reactions, so owners should consult their veterinarian about appropriate dosing and use—particularly for pregnant or medicated pets.
03
Amino Acid
Amino acids are the individual building blocks of proteins commonly added to pet foods to ensure complete, species-appropriate protein nutrition and to correct deficiencies in raw ingredients (examples include lysine, methionine and taurine). They are nutritionally critical—cats in particular require dietary taurine—and appropriate levels support growth, muscle maintenance, immune function and coat health, while imbalances or excess supplementation can cause metabolic issues, so formulations should meet established nutritional standards.
04
Boswellia Serrata
Boswellia serrata is an herbal resin extract used in pet foods and supplements as a functional anti-inflammatory ingredient to support joint health and mobility rather than as a primary nutrient, often standardized for boswellic acid content. It may help reduce inflammation and improve comfort in dogs (evidence in cats is more limited), but can cause gastrointestinal upset or allergic reactions in some animals and may interact with NSAIDs or blood‑thinning medications, so use and dosing should be guided by a veterinarian, especially in pregnant or nursing pets.
05
Collagen
Collagen is an animal-derived structural protein commonly added to pet foods and supplements as gelatin or hydrolyzed collagen to support joint, skin and coat health and to provide digestible connective-tissue protein for dogs and cats. It supplies key amino acids such as glycine and proline important for cartilage and skin maintenance but is low in tryptophan and not a complete protein—so it should not replace higher-quality muscle proteins—and pet owners should note source quality and potential allergen/contaminant concerns.
