Most veterinarians may recommend Dasuquin for dogs because the additional ingredient of ASUs provides the most support. The addition of MSM is also a plus, as it provides the anti-inflammatory effect for conditions such as arthritis. Cosequin supplements are approximately 20% less expensive than Dasuquin. Dasuquin offers additional ingredients not found in Cosequin, and the supplement is more expensive to produce. The main difference between Cosequin and Dasuquin is that Dasuquin contains ASUs, or avocado-soybean unsaponifiables. ASUs help protect joint cartilage by decreasing inflammation and stimulating healing after damage. They work with glucosamine and chondroitin to maximize the benefits of a joint supplement. Most veterinarians will start by recommending one of the Cosequin sprinkle capsules for cats, due to its ease of administration. When considering a new joint supplement for your pet, it’s always best to speak with your veterinarian first to help you determine which product makes sense, based on your pet's health.
