There are so many ways older dogs add value to our lives. In fact, you may not even realise it but they're actually setting a very good example as to how we could live our own lives.
Different breeds of dog are considered senior at different ages. It may also depend on the individual dog. The process of aging will begin slowly and nearly imperceptibly. Your dog will become less active, their metabolism will slow down, and they might put on a little weight. At this time, it's important to make a few changes to help and accommodate your aging canine as they make the inevitable change into their golden years.
