2. Visible Kidney Disease Signs May Take Time
Kidneys are made up of microscopic nephrons. As your dog ages or if the kidneys become damaged, some nephrons begin to die and other reserve (or "resting") nephrons take over. Once there are no extra nephrons remaining, your dog may begin to display signs of kidney damage such as loss of appetite, weight loss, increased thirst, and anemia. However, this often only occurs once 75% of kidney function (2/3 of nephrons) has been lost. This is why it so important you bring your dog to veterinarian at least once a year and remain vigilant for unusual signs in your dog's behavior. It may help prevent your dog from developing kidney disease in the first place.
