The question "Which is the closest pet of human being" can be interpreted in two ways: the animal most biologically or evolutionarily similar to humans, or the pet with the deepest emotional bond to humans.
The chimpanzee and bonobo are humans' closest living relatives. These three species look alike in many ways, both in body and behavior.
Chimpanzees are our closest relative as a species and we share at least 98% of our genome with them. Our feline friends share 90% of homologous genes with us, with dogs it is 82%, 80% with cows, 69% with rats and 67% with mice [1].
Horses. Horses have shared a special bond with humans for thousands of years and are known for building relationships based on trust, respect and mutual care. These majestic animals are known for their gentle nature and ability to sense human emotions by often responding with calmness and affection.
Chimpanzees have been subjected to countless hours of research with the goal of better understanding their cognition. The result is that we can confidently say that chimps are one of the most intelligent species on earth. Humans share 99 percent of our DNA with chimps, so this should come as no surprise.
The animal that is often cited as being "98% human" is the chimpanzee (and bonobo, which is very closely related), sharing a significant amount of DNA due to our close evolutionary relationship, though the exact percentage is debated and depends on how it's measured, with figures ranging from around 84% to 98% depending on the comparison method used, with some newer analyses showing larger differences.

💡 Chimpanzees share around 98-99% of their DNA with humans, making them our closest relatives in the animal kingdom! At the Center for Great Apes, our chimpanzee residents amaze us every day with their intelligence, curiosity, and playful personalities.
The most famous example is the dodo, which owed its extinction in large part to a lack of fear of humans, and many species of penguin (which, although wary of sea predators, have no real land predators and therefore are very bold and curious towards humans).
We actually share more DNA with cats than we do dogs.
Dogs and wolves have many outward similarities. After all, the two species descend from a common ancestor. In fact the two species share 98.8% of the same DNA. They can even interbreed (although their offspring are typically not fertile).

Chimpanzees are our closest relative as a species and we share at least 98.8% of our genome with them. Our feline friends share 90% of homologous genes with us, with dogs it is 82%, 98% with pigs, 80% with cows, 69% with rats, 67% with mice and 65% with chickens [1].
Dogs are famously known as “man's best friend” for a good reason. Their loyalty, affection and eagerness to please have made them beloved companions worldwide. Dogs form strong emotional bonds with humans, offering comfort, protection and unconditional love.
Chimps are our closest living relative. But other human species that went extinct, like Neanderthals, are more closely related.
Based on an examination of our DNA, any two human beings are 99.9 percent identical. The genetic differences between different groups of human beings are similarly minute. Still, we only have to look around to see an astonishing variety of individual differences in sizes, shapes, and facial features.
Babies are created when a sperm cell (containing 50% of the biological father's DNA) fertilizes an egg (containing 50% of the biological mother's DNA) to create an embryo with a full complement of DNA. A baby's biological gender is determined by the sex chromosomes they inherit.
It is not uncommon for Ancestry Composition Inheritance to report that a son or daughter inherited slightly more or less than 50% from each parent. This is because Ancestry Composition relies on the autosomes (chromosomes 1–22) and the X chromosome(s) to calculate Inheritance.
The Amur leopard is one of the rarest big cats in the world, with only around 100 individuals left in the wild.

While it was traditionally thought to be sponges, most (though not all) molecular evidence actually supports ctenophores branching off before sponges, which would make them the most distantly related animals.
For example, Afghan Hounds have the lowest adaptive intelligence, which makes them the least intelligent dog.
Most loyal dog breeds are good family dogs, though some might be better suited for older children.
