As our dogs get older, some of the changes we may notice such as a few grey hairs or a slightly reduced activity level have no impact on health. However, the deteriorative changes that may negatively affect a senior pets overall health and quality of life, such as those associated with illness, changes in mobility, changes in cognitive function and the development of behavioural problems are referred to as senescence.
While few diseases are diet induced with the exception of obesity, many other diseases are diet-sensitive, meaning that diet can play a role in managing the condition. Examples of diet-sensitive conditions include chronic renal disease, diabetes mellitus, and arthritis. Other changes may impact on food intake and subsequent nutritional status such as gum disease, tooth loss, reduced appetite and changes in taste and smell. These are all important factors to consider when planning how best to support the nutritional needs of older dogs.
