As pets age, two kinds of changes often occur. The first is age-related change such as vision or hearing loss. These are normal and generally cannot be prevented. The second kind is pathological change or disease such as arthritis which can slow your pet down and cause discomfort. These are, to some extent, preventable or can be successfully managed. In both instances it is also possible to help your pet maintain a comfortable lifestyle by making small changes around the house and being mindful of your pet’s needs.
