The age of a dog depends on its teeth

The dog’s deciduous teeth

2(Di3/3, Dc1/1, Dp3/3)=28. Is this Morse code?
To explain, it means dividing all the dog’s teeth into four areas: upper left, lower left, upper right, and lower right. In one area, there are 3 incisors, 1 canine, and 3 premolars. There are a total of 28 teeth in the 4 areas.

Dog Permanent Teeth

2(I3/3,C1/1, P4/4, M2/3)=42.
In an area, there are 3 incisors, 1 1 canine tooth and 4 premolars. There are 2 molars on the top and 3 molars on the bottom. There are 42 teeth in total.
How do teeth tell your age? For puppies, it mainly depends on when the deciduous teeth come in and when the teeth are replaced. How to distinguish deciduous teeth from permanent teeth? Deciduous teeth are thinner and pointed, while permanent teeth are stronger. For example, in the picture below, the one on the left is the canine tooth of the deciduous tooth, and the one on the right is the canine tooth of the growing permanent tooth.

Time of emergence of deciduous teeth

Incisors: Dogs are 3-5 weeks old
Canine teeth: Dogs are 3 -6 weeks old
Premolars: Dogs 4-10 weeks old

After the deciduous teeth fall out, the time for permanent teeth to appear

Incisors: Dogs are 3-5 months old
Canine teeth: Dogs are 3.5-6 months old
Premolars: Dogs 3.5-6 months old
Molars: Dogs 3.5-7 months old
It’s hard to remember, so it’s simpler, if some of the teeth have been replaced If some of them are still deciduous teeth, the best estimate is 4-5 months. The time when the last baby tooth has just been replaced is about 6 or 7 months.
In adulthood, teeth can also be used to estimate age. If the teeth are often white and shiny, it is usually about one year old. Dogs will usually start to have tartar when they are two or three years old. Note that tartar will start to accumulate on the molars first. If there is a lot of tartar or the teeth are worn, they are old. But this also has a lot to do with the dog’s usual habit of cleaning his teeth.

The age of a dog depends on its weight

Because the weight of dogs varies greatly between breeds, it is difficult to use this as a standard. [1 pound (lb) = 0.9071847 pounds]

A dog’s age depends on its hair

Just like people, a dog’s hair will turn gray and white as it gets older. Dogs around 7 to 10 years old will see signs of graying in their hair.

The age of a dog depends on its eyes

As the dog ages, the lens of the eye will begin to age, causing symptoms similar to cataracts. The scientific name is nuclearsclerosis. You will find that their pupils are not as clear as before, and will feel a little cloudy and white.
