Your dog is also aging and as in humans, it shows many signs of aging over time. Only all dogs do not age the same way. This varies for example according to size: smaller dogs live longer than big dogs. In fact, they age more slowly and therefore have a longer life expectancy. Thus, the nutritional requirements are not the same depending on the size of the dog. Here is a small summary of the growth time of your dog,
according to its size, but also its age of maturity.Small dogs age less quicklyA small dog has a growth duration of about 10 months. He reaches his age of maturity from the age of 8.A medium-sized dog has a growth duration of about 12 months. He reaches his age of maturity from 7 years old.A large dog has a growth duration of about 15 months. He reaches his age of maturity from the age of 5.
A very large dog has a growth duration of about 18/24 months. He reaches his age of maturity at 4 years old.So, the bigger your dog is, the slower his growth is. However, it will reach maturity more quickly, which means that it ages faster and sooner than a small dog.
Of the 14 race with the longest lifespan, there are of course small dogs. The top five in the ranking are: the toy poodle (14.63 years old), the Tibetan spaniel (14.42 years old), the lhasa apso (14.33 years old), the border terrier (14 years old), and the cairn terrier (14 years old).
On the other hand, at the bottom of the ranking, there are large dogs, so-called “giant” breeds: the bullmastiff, leonberg, Saint Bernard, Great Dane….
However, this study notes exceptions, particularly for English bulldogs and shar-pei, which have a median life expectancy of about 6 years.
Finally, the study notes that the main causes of death are cancer (27%), old age (without further precision, at 18%), and heart disease (18%).
