A dog that is 10 years old is equivalent to a human being who is about 60 years old, and is already an elderly dog. During this period, their state will become heavy, their vision will be weakened, their movements will be slow, and their sleep time will increase. Therefore, dogs at this stage need more careful care from their owners.

A dog is a puppy from birth to 1 year old, an adult dog from 2 to 5 years old, a middle-aged dog from 6 years old, and starts to enter old age after 7 years old. As the 10-year-old dog's own mechanism deteriorates, its reproductive capacity stops, its back becomes curved, its hair becomes rough and dull, its movements are slow, and its sleep time increases.
Dog’s toenails will also gradually turn from white and transparent to yellow and dull as they age; due to calcification or hardening, they usually no longer make a crisp sound when trimmed, but If it becomes brittle and brittle, it means that the dog has entered old age. After the age of 10, the hearing of dogs begins to decline, and they will suffer from varying degrees of deafness. Sometimes they will not be able to hear their owner's calls.
When a dog reaches the age of 10, his behavior will become sluggish and laborious, and sometimes it will even become difficult to complete some simple commands that he used to do before, showing signs of dementia; some dogs will wake up in the middle of the night. When it comes, it barks suddenly, gasps for air, and looks sad.
