Do you want to know, how old your dog is ? or do you want to confirm his age according to scientific standards? Here are important things you should know before you can bet on your dog’s age! In this guide, we will tell you the correct scientific method to know your dog’s age.

Why it is hard to guess a dog’s age?

Guessing a dog’s age by yourself is a hard task, especially if you have adopted one. There is no parameter that can tell you the age of a dog 100% accurately. But there are scientific techniques that can estimate the dog’s age close to the real age.

There are many factors that can alter the results. Environmental factors impart major effects on age determination. Diet, feeding habits, Stress & disease conditions also take us to the wrong result.

Dog age V/S human age (brief comparison)

There is a significant difference in the life span of humans and dogs. While a dog’s average lifespan is 10-13 years, humans can live an average of around 79 years. This is approx 6-7 times fewer humans.

Dog’s growth speed also differs. Pup grows much faster than us. It is of great significance to know the actual age of your pup so that you can take care of and feed them accordingly. Like us, a dog’s body requirement is also different at different stages of life.

“It is quite surprising that if a human baby and a pup are born on the same day, the pup will reach the same maturity in just 6 months, whereas the human baby will reach there after 7.5 years.”

Older methods of dog’s age calculations?

You might have heard that “one year of a dog’s life is equal to seven human years“. Since the year 1950, this is the popular calculation used for calculating the age of dogs. Even though we have been using this method for a long time, but the answer we get is not precise.

However, there was no such scientific reason behind this rule as this is based on general observations. Another explanation for this method is that it is based on the ratio of the average life of humans and dogs.

Average life of humans is around 70 yrs.

Average life of dogs is around 10 yrs.

Also, we can’t say that it is a wrong formula for guessing a dog’s age as it gives a general idea quickly without much effort. As humans and dogs are similar in many ways so this method is helpful even to a layman. Anyone can understand their dog better after calculating and comparing it to a human baby. It becomes easier to decide feeding and caring habits at different ages.

How to differentiate baby teeth and adult teeth in dogs?

Most dogs have 28 deciduous teeth and 42 permanent teeth. The deciduous teeth begin to erupt at 3 to 5 weeks of age, while permanent teeth usually erupt around 4 to 5 months. All permanent teeth are present by the time the dog reaches 7 months of age.

The baby teeth are smaller and darker than the permanent teeth that follow. while Adult dog teeth are sturdier and built to tear, puncture, chew and grind food into smaller parts that are easy to swallow.
