Content: Tartar buildup starts shortly after this. Most dogs will start to show wear on their incisors, the teeth along the front of their mouth, between 3 and 5 years. The wear on the teeth will gradually increase as your dog ages. Significant tartar build-up with evidence of gum disease (look for red, inflamed gums) can be seen after they are 5 years old. Missing teeth usually means that the dog is a senior and could use some dental care. The stage and condition of the teeth can help to give you a good estimate of your dog's age, but remember that there are many factors besides age that can affect their appearance including breed, genetics, chewing behavior, and history of dental care. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/e\/ed\/Calculate-Dog-Years-Step-4-Version-2.jpg\/v4-460px-Calculate-Dog-Years-Step-4-Version-2.jpg","bigUrl":"\/images\/thumb\/e\/ed\/Calculate-Dog-Years-Step-4-Version-2.jpg\/aid1338936-v4-728px-Calculate-Dog-Years-Step-4-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><p>License: <a target=\"_blank\" rel=\"nofollow noreferrer noopener\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}

Assess your dog's size and growth. If your dog is continuing to grow, then he is less than 1 1/2 to 2 years old, depending on overall size. Small dogs have reached their full height and length by around one year of age, but large and especially giant breed dogs may take until they are 18 months to 2 years old.
