How old is my dog - can you determine it by looking at the teeth?

The method of determining a dog’s age by checking its teeth is not very precise. But it can be a hint in case there is no information about the dog. It’s a commonly used method for stray animals someone has got rid of.

How to discover the dog’s age in this case? Just pay attention to how much the teeth are worn down, their color, condition and number. You cannot typically do it for puppies, but rather for older animals.

Young, a few years old (3-5 years) dogs have incisors intact, and slightly worn upper premolars. Older animals over 6-7 years old have noticeably worn incisors and canines. Their shape is also distinctively rounded.

Dog years to human years - how to calculate a dog’s age?

A dog’s age is calculated in accordance with the breed. The smallest dogs mature quicker, but the process of aging is slower for them. It means that after the first year, the dog’s age is:

  • small breeds - 20 years,
  • medium breeds - 18 years,
  • large dogs - only 12 years.

But after 10 years the situation is opposite:
