How to Tell a Dog’s Age at Shelters and Rescues by Their Teeth
One of the most reliable ways to estimate a dog’s age is by examining their teeth. Here’s how vets do it:
1. Puppy Teeth (0-6 Months)
- Newborn to 4 Weeks: No visible teeth.
- 4 to 8 Weeks: Baby (deciduous) teeth begin to emerge.
- 8 to 16 Weeks: Full set of sharp, small baby teeth.
- 4 to 6 Months: Baby teeth fall out and permanent adult teeth replace them.
2. Young Adult Teeth (6 Months – 2 Years)
- Full set of adult teeth (42 total) are present.
- Teeth appear white, clean, and sharp.
3. Adult Teeth (2 – 5 Years)
- Slight yellowing on molars.
- Some plaque and tartar buildup, especially on back teeth.
- Teeth may start showing minor wear.
4. Senior Teeth (5+ Years)
- Visible tartar, especially if dental care was neglected.
- Teeth may be worn down, fractured, or missing.
- Possible gum recession and signs of dental disease.

How to Tell a Dog’s Age at Shelters and Rescues Using Other Physical Clues
1. Coat Condition & Graying
- Young dogs have smooth, soft fur with vibrant color.
- Older dogs may develop gray or white fur, especially around the muzzle and eyes.
2. Eyes & Vision Clarity
- Puppies and young adults have bright, clear eyes.
- Older dogs may have cloudy or bluish eyes due to nuclear sclerosis (a normal aging change) or cataracts.
3. Muscle Tone & Body Shape
- Younger dogs tend to have a lean, muscular build.
- Senior dogs may have less muscle mass, with noticeable fat deposits around the waist.
4. Energy Levels & Joint Mobility
- Puppies and young adults are typically hyperactive.
- Senior dogs may show stiffness, arthritis, or reluctance to jump.
Do Shelters Lie About a Dog’s Age?
Some pet adopters wonder: “Do shelters lie about a dog’s age?” The truth is, shelters don’t intentionally mislead adopters. However, estimating age isn’t always 100% accurate, and sometimes shelters may round up or down to improve a dog’s chances of adoption. If you’re unsure about how to tell a dog’s age at shelters and rescues, consult a veterinarian for a professional assessment.
Shelters rely on visual examinations, dental assessments, and past records to estimate a dog’s age, but these methods have limitations. How to tell a dog’s age at shelters and rescues becomes more challenging when a dog has received excellent dental care or has genetic factors affecting their appearance. Additionally, some shelters may present a dog as younger if they believe it increases adoption chances, especially for older dogs that may otherwise be overlooked.
If you suspect your rescue dog’s listed age might be inaccurate, request a second opinion from a trusted veterinarian. They can assess bone structure, joint health, and overall condition to give a more reliable age estimate. While it’s understandable that shelters do their best with available information, adopters should always follow up with a vet to ensure their new pet gets the right care for their life stage.
Scientific Methods: Dog Age Test & Dog Age Calculator
For a more precise estimate, consider modern scientific methods:
1. Dog Age Test (DNA Testing)
Companies like Embark and Wisdom Panel offer DNA tests that analyze genetic markers to estimate a dog’s age. These tests also provide insights into breed and health risks.
2. Dog Age Calculator
Online dog age calculators, such as the one provided by the American Kennel Club (AKC), estimate a dog’s age based on weight, breed, and health indicators.
