Glucosamine is naturally concentrated in joint cartilage, where it plays an important role in maintaining the smooth working of joints. Daily glucosamine supplements for dogs will protect and lubricate the joints and help to rebuild damaged cartilage, while also relieving arthritic pain. Omega 3 Fatty Acids are proven to reduce joint inflammation and lubricate joints and often help to relieve joint stiffness after periods of inactivity. Feed your dog a diet filled with omega 3 fatty acids, good sources of which are salmon, tuna and sardines. Cod Liver Oil supplements for pets are rich in Omega 3 fatty acids and are easy to add to their food. Swimming is a form of exercise not stressful to the joints and can help to increase mobility and strengthen the joints. Apply heat to affected areas - Heat increases circulation, stimulates muscles, and lessens pain. Use heating beds or a warm bath to soothe your dog's aching joints - ensure that you test the temperature yourself first to make sure it is bearable. Give your dog gentle massages each day - Regular massages reduce muscular tension and help to relieve the aches and pains associated with arthritis.
