Dogs reaching the final one-third of their lifespan undergo a variety of physical and metabolic changes that may cause them discomfort and change their behaviour. For example the senses  sight, hearing, taste and smell  are reduced. Metabolism slows and immunocompetence decreases. Muscle and bone mass decline, and arthritis may affect the joints. There is an increased risk of cardiovascular disease, cancer and endocrine, renal and hepatic disorders. From now on, do take Julie for regular health checkups to your vet, at least once every 3-6 months so that they are able to catch any abnormality and treat it sooner than later.
