1. Tibetan mastiff
This gigantic dog originates in Tibet and belongs to the family of mastiffs or dogos. Its original purpose was to protect sheep from predators such as wolves, leopards and bears. Only with their size does it intimidate the hungriesiesn enemies, although they are actually very harmonious and perfect caregivers. Males can reach heights of up to 76 cm, and the original mastiffs used to weigh between 55 and 90 kg. Although initially used as guardians, as time went on these huge animals were very expensive to maintain by their nomadic owners, and eventually, their numbers began to decrease. This rarity factor is what makes them considered the most expensive dogs in the world: from 2000 to 5000$, according to the seller. With thick fur, the grooming and hairdressing can cost about $70 per visit. Medical expenses can reach up to $3000 for problems such as hip or elbow dysplasia. Its life range is between 12 and 15 years.
