Joints allow your pet's limbs to perform everyday actions like walking, sitting, jumping and running. All joints are cushioned by cartilage, which acts as a shock absorber, helping to prevent bones in joints from grinding together and wearing down. In the course of these everyday activities, joints (especially in larger dog breeds) are subject to a great deal of strain and stress. While designed to cope with daily living, it also makes sense to do all we can to keep pet's joints healthy and flexible. The best way to do this is by living a healthy lifestyle and ensuring they get regular, moderate exercise to promote keeping joints in good shape. But age, wear and tear of the joints over time, or being overweight, can lead to joint swelling. Swelling joints are often associated with symptoms of muscle and joint issues such as tenderness, warmth, redness, inflammation, stiffness and pain. Common symptoms and signs of muscle and joint problems include: morning stiffness, reduced activity, limping, whining or crying when getting up or being picked up, thickening joints, favoring limbs, lethargy, difficulty sitting or standing, and reluctance to jump, run, or climb stairs.
