When it comes to the dog’s longevity, how can you compare the Great Dane with the Chihuahua? Anatomy can explain this: besides the size, the average life span of the dog depends on many other factors. Let’s discover the factors that influence a dog’s average lifespan throughout this blog post.
If you want to help your dog have better health and longer life, here are the factors that affect its longevity.
The process of taking care of dogs
Taking care of your pet will directly affect the dog’s health and average life span. A dog that is well-fed and nutritious, regularly exercised, and exercise will have a longer lifespan.
Not only that, but you should also regularly take your dog to the veterinary clinic to periodically monitor internal health developments.
The natural size of the dog
A study by the University of Göttingen, Germany on 56,000 dogs from 74 different dog breeds showed that the average life expectancy of a dog is reduced by 1 month if they gain 4.4 pounds (1.98 kg). Larger breeds usually grow faster and age more quickly.
As a result, large breeds often have a shorter lifespan than small breeds. For example, the Irish wolf-dog has an average weight of 50kg, height between 70-90 cm has only an average life expectancy of 7 years. Meanwhile, Jack Russell Terriers weighing only about 5-6kg have a life expectancy of up to 13-16 years.
Purebred and hybrid dogs
Purebred dogs are more at risk because they contain genes that carry the genetic disease for each breed. In contrast, hybrids with two or more lines experience fewer health problems and have a longer lifespan.
Caesarean section and natural birth
This is a factor that can positively affect the longevity of the female dog. Studies show that these surgeries can help reduce the risk of certain types of cancers in dogs. Especially cancer-related to the ovaries, breasts, and testicles.
Hopefully, the article will help you know the average life span of dogs to choose to buy healthy breeds with a long lifespan. In addition, you also need to have full knowledge to take care of your dog.
