Glucosamine Rash on Dogs
Glucosamine for dogs is an amino sugar complex that is often used to release bone and joint pain in older dogs. Dogs suffering from arthritis are often prescribed glucosamine to reduce inflammation and pain. However, as with any other medication, there can be side effects. Some pet owners report a glucosamine rash on dogs taking the medication regularly.
Glucosamine helps arthritic dogs by healing painful joints. When taken correctly, this amino sugar stimulates protein production in the joints. This helps to build and repair the connective tissues of tendons and ligaments. Though dogs’ bodies produce it naturally, over time the body can begin producing less or stop all together. This can lead to the painful joints of osteoarthritis.
The glucosamine for dogs that is given as a supplement is a sulfate drug. It is often derived from shellfish, where chitin is available. Though glucosamine is not an allergen by itself, if is it poorly prepared from the shellfish it can cause a reaction. Also, some animals cannot handle sulfur medications well. Negative side effects such as a glucosamine dog rash, nausea, fever, and diarrhea have all been reported.
It is important that a dog who is taking glucosamine and displaying any of the negative side effects be taken off of the medication immediately. Though it is possible for these side effects to be caused by other illnesses, only a veterinarian can safely diagnose the cause. For dogs who are dealing with side effects from the glucosamine, there are vegetarian and non-sulfate versions of the supplement available.
Dogs who are suffering from joint pain due to osteoarthritis can greatly benefit from taking a glucosamine supplement. Many owners have reported marked improvement in their dogs pain and movement after taking this medication. Side effects can occur, however, and owners should be aware of this.
