Cosequin may help to alleviate pressure on the dog's joint tissue during strenuous activity.

Like humans, dogs are more prone to develop arthritis as they age. Cosequin is a medication to help provide relief from arthritis in afflicted dogs. According to the Vet Info website, Cosequin is a natural supplement that contains the ingredients chondroitin sulfate, glucosamine and manganese ascorbate, which work together to strengthen joint tissue. Dispense the pills after meals to help prevent negative side effects, which are uncommon.

Gastrointestinal Upset

Although side effects from Cosequin are rare, gastrointestinal upset has been reported in certain cases. The most prevalent symptom is diarrhea, but vomiting, indigestion and an overall upset stomach have also been reported on occasion. These symptoms tend to occur when the supplement is first introduced into the dog's system and typically subside relatively quickly. Because the initial dosage of the supplement remains high for about the first two weeks, the dog may also experience a decrease in appetite. If the dog has a particularly sensitive stomach, administering the medication either with or right after meals can help reduce the incidence of any kind of upset.


Allergic Reaction

Dogs that have an allergy to beef products can have allergic reactions when they take chewable Cosequin tablets, which contain beef. According to the Pet Education website, beef is one of the most common foods that cause an allergic reaction in dogs. Symptoms can include hair loss, excessive scratching, hot spots, skin infections and an increased incidence of bowel movements. Veterinarians may suggest that these dogs switch to Cosequin capsules.


Increased Mobility

Different dogs react differently when they take a nutritional supplement, and some may not receive much benefit. Many dogs do respond favorably to Cosequin, and a pleasant side effect can be moderate to enhanced relief from arthritis pain and an increase in overall mobility. The AltVetMed website recommends using the supplement Cosequin over any anti-inflammatory drugs and advises pet owners to watch for gradual improvements in their dog's comfort level when the dog performs everyday activities like climbing up stairs, going for walks or even just getting up. Many owners say that, as the pain subsides, they also notice an improvement in their dog's overall attitude.
