Cosequin has become a popular treatment for arthritis in dogs and other animals. It’s widely used and is considered safe. However, what happens if your dog eats too much Cosequin?
In this article, we’ll take a look at what Cosequin is and whether or not it can make your dog sick. Let’s get started!
What is Cosequin?
Cosequin is an OTC supplement that works to support dogs’ joints. In dogs who have arthritis, Cosquin can help lower pain levels while also strengthening joints to help maintain normal movement. This product comes in various forms, including tablets and chews for dogs.
Cosequin contains glucosamine, which acts as an anti-inflammatory. It also contains chondroitin, which works to stop the destruction of the cartilage. When it comes to effectiveness, there haven’t been many studies on whether or not glucosamine and chondroitin are effective but there are some promising results so far.
Cosequin is considered safe for dogs. However, can too much Cosequin make a dog sick?

Treatment for Glucosamine Overdose in Dogs
At the vet’s, they will perform a complete physical on your dog, which may include lab work and other tests. If the overdose happened fairly recently, then the vet may induce vomiting and use activated charcoal to help remove the toxin from your dog’s digestive system. Your dog may also need an IV to replace fluids and give medications to treat symptoms as they come up.
Depending on the severity of your dog’s symptoms, he may need to stay in the hospital for a day or so. The vet may want to monitor the dog’s symptoms and make sure he’s stabilized before going home.
The good news is that in most cases when a dog receives prompt medical treatment, they will go on to make a full recovery!
