Birth to 6-8 weeks old
During this period is when you will see the full set of baby teeth come in.
At the start, they just have little gums before the baby teeth start poking through.
12 weeks to 16 weeks old
This is when you start to notice those baby teeth falling out.
And that means that your puppy is teething again before the first adult teeth start to come in.
Watch the front teeth for the first new adult teeth.
16 weeks to 24 weeks old
This is when the rest of the adult teeth start filling in your dogs mouth.
These are the back teeth, which are the last adult teeth to come in for dogs.
7 months to 2 years old
Sometime in this period is when noticeable tartar starts to build up on your puppy’s teeth.
Often this is most noticeable on the back teeth.
3 years to 5 years old
During this period, the teeth will get more tartar buildup.
You’ll also notice signs of wear on the dog’s teeth.
5 years to 10 years old
During this stage of your dog’s life, there will be more noticeable wearing down of the teeth.
Some dental issues will also likely be present in the dog’s mouth.
10 years to 15 years old
Here at the last stage of a dog’s life, the mouth will likely have some missing teeth.

If you’re still having trouble assessing the age of your puppy, then there are some other options for you to try.

Often is is easy to tell an older dog from a younger one simply by looking at their coat.
Older dogs tend to have gray, or lighter, fur in their coats.
An older dog may also exhibit problems like joint pain or pain from canine arthritis while walking.
2. Check the eyes
If you’re getting a recently born puppy, then the eyes may give away the age.
Until they are two weeks old, puppies are mostly blind and they eyes have this grayish tint to them.
3. Check the hearing
Puppies aren’t born being able to hear all that well.
In fact, it is not until they are between the ages of 2 weeks old and 4 weeks old that their ear canals open up enough for them to be able to hear properly.
4. Is your puppy clingy?
Until puppies reach around 12 weeks old, they are incredibly clingy.
They don’t yet have the confidence to venture out on their own and just want to stay close to you and be comforted.

While canine teeth won’t give you an exact age, they do give you a pretty good idea of the puppy’s age.
