For thousands of years, humans have been taking the health of dogs for granted.
In general, some dog breeds are considered to be healthier than others, particularly working dogs.
Here are the healthiest dogs in the world;
1. Mixed Breeds:
If inner-breeding and over-breeding are the source of many inheritor health problems of dogs, it's reasonable to assume that conventional breeds will be hearty, and healthier.
It's not like mixed breeds can't inherit genetic issues from their parents, but however, it's less likely for both parents to be predisposed to same issues.
2. Siberian Husky:
Siberian Husky, and other northern working dog breeds closely resemble wolves, the ancient ancestors of the domestic dog, indicating that they had undergone less drastic human intervention.
3. Australian Cattle Dog:
Australian Cattle Dog is traditionally bred for high intelligence, and problem-solving skills.
The Australian Cattle Dog tends to be among the healthiest of modern dog breeds.
On average, the Australian Cattle Dog can live 10 to 13 years.
4. Airedale Terrier:
Bred to hunt small games and kill rodents like rats, and ottas, in the English countryside the Airedale Terrier is very healthy.
The Havanese is quite a hearty dog, and can live up to 16 years.
6. American Water Spaniel:
In general, the American Water Spaniel is a healthy breed, a working dog that hails from the great lake region, where it was developed to hunt fish, and water fowl.
The American Water Spaniel lives 10 to 12 years, with only minor health issues.
7. American Foxhound:
The American Foxhound was bred for the main purpose of hunting foxes.
8. Border Collie:

Most Border Collie live long, and energetic lives of up to 15 years.
9. Cairn Terrier:
