Inspect your dog's teeth. Look at the stage and condition of the teeth. Determine what stage the teeth are at. Puppies will usually have all of their baby teeth by the time they are 8 weeks old and should have all of their permanent teeth by the time they are 6 to 7 months old. They start getting their permanent canine teeth, the longest ones, usually right at 6 months old, which makes this the easiest time to accurately age a puppy. If they have all of their permanent teeth and they are white and clean, they could be up to 1 1/2 to 2 years, but probably around 1 year old. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/1\/18\/Calculate-Dog-Years-Step-3-Version-3.jpg\/v4-460px-Calculate-Dog-Years-Step-3-Version-3.jpg","bigUrl":"\/images\/thumb\/1\/18\/Calculate-Dog-Years-Step-3-Version-3.jpg\/aid1338936-v4-728px-Calculate-Dog-Years-Step-3-Version-3.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 the condition of the teeth. Between the ages of 1 and 2 years old, many dogs will start to show some yellowing on their back teeth.
