What To Do If Your Dog Is Allergic To Glucosamine


Most joint support supplements contain glucosamine, which is an ingredient that is often given to middle age dogs and cats to help relieve the pain and soreness within their joints. It is especially helpful for pets with deteriorating joints, dysplasia (hip or elbow) and arthritis. While glucosamine is generally well-tolerated by most dogs, a small percentage may have an allergic reaction. The most likely culprit is a food allergy to shellfish since glucosamine is derived from shellfish. Fortunately, there are alternative joint support supplements that can be effective for dogs with this allergy.

Symptoms Of A Glucosamine Allergy In Dogs

Identifying an allergic reaction to glucosamine in dogs can be challenging, as allergies may manifest in various ways. Here are some signs that could indicate a potential allergic reaction to glucosamine in your dog:

Skin Issues - Allergic reactions often present with skin problems such as itching, redness, hives, or rash. If you notice your dog excessively scratching, licking, or chewing at their skin after starting a glucosamine supplement, it could be a sign of an allergy.

Gastrointestinal Distress - Some dogs may experience diarrhea from glucosamine. Dog owners may observe that the digestive symptoms resolve as soon as they stop giving the joint support supplement.

Swelling - Swelling, especially around the face, muzzle, or eyes, can indicate an allergic reaction and may be a side effect of glucosamine in dogs.

Respiratory Symptoms - In severe cases, allergic reactions can lead to respiratory issues such as coughing, wheezing, or difficulty breathing. Breathing difficulties always require immediate veterinary attention.


Alternative Joint Support Supplements For Dogs Allergic To Glucosamine


If your dog cannot take glucosamine, consider a safe alternative joint supplement for dogs with allergies. Collagen, Curcumin and CBD Oil are all effective in reducing pain and inflammation as well as supporting dog joint health.

Ultra-Flex Collagen for Pets – A natural “whole-food” supplement that strengthens cartilage, rebuilds connective tissue and supports joint health. Collagen is the "cellular glue" that is found in the bones, muscles, skin, tendons, and digestive tract of your pet. As pets age, natural collagen production declines and can lead to decreased elasticity and stability in the joints, muscles and connective tissue. Ultra-Flex Collagen For Pets contains NEM® brand eggshell membrane - a safe, all-natural whole-food source containing three varieties of collagen, glycosaminoglycans (GAGs) such as chondroitin sulfate, glucosamine, hyaluronic acid, and enzymes for enhanced absorption and bioavailability. Excellent choice for pets that are allergic to glucosamine or that are picky about herbal formulas.


K9 CurcuMagic - A scientifically proven, natural anti-inflammatory for dogs that contains a patented combination of three curcuminoids, along with turmeric essential oil. These are the strongest, most protective and best-researched constituents of the herb turmeric that act as powerful free-radical scavengers. Curcumin is helpful in reducing inflammation, whether acute or chronic, caused by physical injury, joint wear and tear (as in osteoarthritis) and inflammatory conditions such as hip or elbow dysplasia. Helps to relieve pain and improve mobility. K9 CurcuMagic is especially bioavailable (pets can get the most benefit) because of the added essential oil, to improve absorption. This is why K9 CurcuMagic is more beneficial for pets than just sprinkling turmeric spice on your dog's food. For dogs over 15 pounds.


Happy Paws Organic Hemp Extract For Dogs - A high-quality hemp CBD oil that can help improve your pet’s overall well-being. Just a few drops of this non-psychoactive tincture is an effective way to reduce anxiety, inflammation and relieve pain. Happy Paws is a full-spectrum hemp oil containing CBD, CBG, CBN, and CBDA. Rigorous independent laboratory testing ensures purity. Each 1oz bottle contains 550mg of full-spectrum hemp extract in an unflavored all-natural coconut oil base. Organically grown in Colorado. Happy Paws Drops can help pets with anxiety/stress, cancer, pain, digestion, dementia, inflammation, seizures and more!
