Why Is A Dog Year That Long?
Size and breed play a role in determining the period of how long a dog is. It is found and also known according to results that smaller-sized dogs tend to live longer than larger-sized ones. That means the smaller-sized breed dogs mature more quickly in the first few years of life as compared to dogs belonging to larger-sized breeds.
A dog’s first year generally includes many phases observing to which one can observe how close or how far your dog is to complete his or her first year. By the first 8 weeks of a dog’s birth, all of his or her baby teeth are in. By the period of 7 months, baby teeth are shredded off and all permanent teeth are in. Next, by the period of 1 to 2 human years, the teeth become duller and you may observe the back teeth to have some yellowing as well.
After a span of 3 to 5 human years, you might see all the teeth of your dog have tartar buildup and some tooth wear. Following this, after a period of 5 to 10 years, the teeth of your dog start to show more wear and may show signs of disease as well. Lastly, after a period of 10 to 15 years, the dog’s teeth are worn, and heavy tartar buildup is quite visible. You might also observe some teeth missing. Once you see these signs, you can be sure that your dog’s first-year completion is near.
The period of the first dog year is completely unequal to the second dog year and so on.
Considering that the second year of dogs belonging to giant-sized breeds is about 22 human years long. Whereas, on the other hand, the second dog year of large-sized breed dogs, medium-sized breed dogs, and small-sized breed dogs generally ranges around 24 human years.
