Content: Between 3 and 5 years of age, a dog's teeth are typically somewhat worn, and tartar buildup may be evident. Teeth become significantly worn between the ages of 5 and 10 years, and beyond 10 years of age most dogs have worn teeth and significant tartar buildup. Missing teeth may be a sign of accident, injury or old age, but many dogs also are born with some teeth missing. Step 2
Observe your dog moving around the indoor or outdoor environment. If he moves stiffly and slowly, that is a sign that your dog is most likely in the second half of his expected natural lifespan. Just as humans commonly experience problems such as arthritis in later years, dogs' skeletons typically become weaker and stiffer as they age. However, a young dog may move stiffly or awkwardly if she has suffered an injury in the past. Step 3
Look at your dog's coat and skin. Like humans, dogs usually develop gray hair as they age. Normally this happens by the time a dog is around 7 years old, but some dogs may go gray at an earlier age.
