Note changes in teeth for an older dog. As a dog ages, their teeth change. Changes in teeth can help you assess a dog's approximate age. Ridges on the incisors change as a dog ages. By the time the dog is three years old, the ridges will have worn off the bottom incisors. By five years old, the ridges will have worn off the upper incisors as well. A small amount of ridges on the upper front four teeth indicate your dog is between three and four. By seven, a dog's teeth are completely smooth. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/c\/c6\/Determine-Your-Dog%27s-Age-Step-3-Version-2.jpg\/v4-460px-Determine-Your-Dog%27s-Age-Step-3-Version-2.jpg","bigUrl":"\/images\/thumb\/c\/c6\/Determine-Your-Dog%27s-Age-Step-3-Version-2.jpg\/aid8850335-v4-728px-Determine-Your-Dog%27s-Age-Step-3-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>"}
