Common Signs Seen in Senior Dogs
All dogs get older. And like us, dogs age at distinctive rates, especially dogs of different breeds and size. For example, giant breed dogs like Great Danes are generally considered to be a senior by roughly 5-6 years old, whereas a smaller breed dog like a Chihuahua would probably only enter the senior stage between 10-11 years. Pay close attention to following signs and issues associated with aging, and visit your veterinarian regularly (many vets recommend twice a year for senior dogs) so that these issues do not become an insurmountable problem as your beloved dog enters his senior years.
