Dasuquin is the number one veterinarian-recommended joint supplement for dogs and cats, manufactured by Nutramax Laboratories. It combines three active joint-support ingredients: glucosamine, chondroitin sulfate, and ASU (avocado/soybean unsaponifiables). The inclusion of ASU is what sets Dasuquin apart from the more basic Cosequin (also by Nutramax), which contains only glucosamine and chondroitin. Dasuquin is available without a prescription and is widely used as both a preventive supplement for at-risk breeds and as supportive care for dogs and cats with established osteoarthritis.
What Is Dasuquin Used For?
Dasuquin is recommended for joint health support:
- Osteoarthritis — supporting joint function and comfort in dogs and cats with diagnosed arthritis
- Joint health maintenance — preventive use in large-breed dogs, active dogs, or aging pets
- Post-surgical joint support — after ACL repair, joint surgery, or other orthopedic procedures
- Cartilage protection — supporting healthy cartilage metabolism
- Multi-modal arthritis management — commonly used alongside prescription pain medications (NSAIDs, Librela, gabapentin)
Dasuquin is a supplement, not a prescription medication. While it can provide meaningful joint support, it is not a substitute for prescription pain management in dogs or cats with significant arthritis pain.
How Does Dasuquin Work?
Each of Dasuquin’s three active ingredients contributes to joint health through different mechanisms:
Glucosamine:
- Serves as a building block for glycosaminoglycans (GAGs), which are essential components of cartilage and joint fluid
- Supports production of new cartilage matrix
- May have mild anti-inflammatory properties
Chondroitin sulfate:
- A major structural component of cartilage
- Inhibits destructive enzymes (metalloproteinases) that break down cartilage
- Supports water retention in cartilage, maintaining its shock-absorbing properties
ASU (Avocado/soybean unsaponifiables):
- The key differentiator from basic glucosamine/chondroitin products
- Inhibits inflammatory mediators (IL-1, IL-6, TNF-alpha) in joint tissue
- Stimulates collagen synthesis by chondrocytes (cartilage cells)
- Reduces cartilage breakdown enzymes
- Studies show ASU enhances the effects of glucosamine and chondroitin when used together

Dasuquin is typically given at a loading dose initially, then reduced to a maintenance dose. Follow the product label or your veterinarian’s instructions.

| 10-29 lbs | 1 chewable daily | 1 chewable every other day |
| 30-59 lbs | 2 chewables daily | 1 chewable daily |
| 60-120 lbs | 3 chewables daily | 1-2 chewables daily |
| Over 120 lbs | 4 chewables daily | 2 chewables daily |

|---|---|---|
| Dasuquin for Cats | 1 capsule daily | 1 capsule every other day |
Sprinkle capsule contents over food for cats.
How to Give Dasuquin to Your Dog or Cat
- Chewable tablets (dogs): Flavored soft chews that most dogs accept as treats.
- Capsules (cats): Open and sprinkle over food.
- Can be given with or without food, though most owners give with meals.
- Start with the loading phase (higher dose for 4-6 weeks) to build up joint support, then transition to the maintenance phase.
- Joint supplements take time — allow 4-6 weeks before evaluating effectiveness.
- Can be used safely alongside prescription medications including NSAIDs, Librela, gabapentin, and other arthritis treatments.
Side Effects
Dasuquin has an excellent safety profile.
| Common Side Effects | Serious Side Effects (Contact Your Vet) |
|---|---|
| Mild GI upset (soft stool, gas) | Allergic reaction (rare) |
| Mild decrease in appetite (uncommon) |
Side effects are uncommon. GI upset is typically mild and transient, often resolving by reducing to the maintenance dose.
Drug Interactions
- No significant drug interactions are known with Dasuquin.
- Safely used alongside NSAIDs, corticosteroids, gabapentin, and monoclonal antibody treatments (Librela, Solensia).
- Glucosamine may theoretically affect blood sugar in diabetic animals — monitor if your pet has diabetes.
Contraindications
- Known allergy to any ingredient (including soy or avocado)
- Shellfish allergy — glucosamine is often derived from shellfish (though allergic cross-reactivity is debated)
- Not a substitute for veterinary evaluation and diagnosis of joint conditions

Frequently Asked Questions
What is the difference between Dasuquin and Cosequin? Both are made by Nutramax Laboratories. The key difference is that Dasuquin contains ASU (avocado/soybean unsaponifiables) in addition to glucosamine and chondroitin, while Cosequin does not. ASU provides additional anti-inflammatory and cartilage-protective benefits. Dasuquin is considered the premium product and is the one most veterinarians recommend. Cosequin is a more affordable option that still provides basic joint support.
Do joint supplements really work? The evidence for glucosamine, chondroitin, and ASU in dogs is moderate — some clinical studies show meaningful improvement in mobility and comfort, while others show more modest benefits. Individual responses vary. Most veterinary orthopedic specialists view joint supplements as a reasonable part of multimodal arthritis management but emphasize that supplements alone are insufficient for significant arthritis pain. They work best when combined with weight management, appropriate exercise, and prescription pain management as needed.
How long before I see results? Most pets require 4-6 weeks of consistent use at the loading dose before noticeable improvement. Some owners report subtle improvements in mobility and willingness to exercise within 2-3 weeks. If no improvement is seen after 8 weeks, discuss alternative or additional treatments with your veterinarian.
Can I give Dasuquin preventively? Yes, many veterinarians recommend starting joint supplements before arthritis develops in breeds predisposed to joint problems (Labrador Retrievers, German Shepherds, Golden Retrievers, etc.) or in highly active dogs. The evidence for preventive use is limited, but the safety profile makes it a reasonable option.
