Surprisingly, humans share approximately 84% of their DNA with dogs. This genetic overlap has profound implications for everything from medical research to the understanding of evolution. Humans and dogs are both mammals, and like all mammals, they share a significant portion of their genetic code. In the case of humans and dogs, about 84% of the genes found in dogs share a similar locus in the human genome, reflecting deep evolutionary ties. The fact that we share around 84% of our DNA with dogs highlights the biological and evolutionary connection between our species. Genetic overlap is often misunderstood, it does not suggest that 84% of the dog genome is identical base-for-base with that of a human, instead, it means that 84% of genes in dogs are similar in function or position to human genes.

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. Human and chimpanzee DNA is so similar because the two species are so closely related. They both descended from a single ancestor species 6 or 7,000,000 years ago. As they evolved, their DNA changed as it was passed from generation to generation. By virtue of being the same species, all humans share 99% of their genome, which means that all humans are 99% genetically similar. Our bodies are made up of 3 billion genetic building blocks, or base pairs. Of those 3 billion base pairs, only a tiny amount are unique to us. The remaining 1% of genes that are different explain the variations in characteristics, such as colour of hair, eyes and skin, and also risk for certain diseases. Read about how much DNA relatives share including siblings, twins & cousins, as well as what percentage of DNA humans share with dogs.

When comparing the genetic makeup of humans with other species like dogs or primates, surprising similarities become apparent. The common dog, scientifically classified as Canis lupus familiaris, shares a surprising amount of genetic code with humans – approximately 84%. Note that the high percentage of shared DNA between humans and dogs does not suggest humans are 84% canine. Instead, it conveys that there are many similarities between the genetic sequences that make up their respective genomes. Humans and dogs share a common ancestor that lived approximately 90–100 million years ago. The percentage of DNA that two species share is also influenced by how recently they shared a common ancestor. Dog (Canis lupus familiaris) 84%

Yes their DNA, like every living thing’s DNA, is made of the same building blocks of A’s, T’s, G’s, and C’s. But their DNA isn’t exactly alike. All those A’s, T’s, G’s, and C’s are put together in different orders for dogs and people. You and a dog have many more differences within and outside of your recipes. Humans and dogs have about the same number of genes, about 20,000 or so. The differences between you and Lassie have more to do with having a few different recipes and with changes within the ones you share. Dogs and humans have different versions of the same genes. But the group that first sequenced the dog genome found that they could match up about 73% of dog DNA to human DNA. And they found that almost all of a dog's genes are also found in humans.

Humans and dogs share more than 80% of their DNA. Research has found that many groups of genes, such as those linked to digestion, neurological processes, and cancer development, are extremely similar between humans and dogs. When DNA testing in humans finds evidence linking particular genes to diseases, this knowledge may be transferable to the same genes and diseases in pets. Studies have found that some genetic variants specifically associated with canine cancer cells match those found in human cancer cells. The drugs developed for treating human cancer had similar effects on the canine cancer cells as they did on human cancer cells. Humans and cats share almost 90%. These high percentages of similarities make genetic sequencing in all three species mutually beneficial. Advancements in both human DNA testing and pet DNA testing can potentially be applied across species.
