Dogs do not belong to the order of Felidae.
The order of Felidae includes all cats from lions to house cats.
Dogs are in the order of Carnivora which includes all meat-eating animals.
This is determined by their teeth; dogs have carnassial teeth which are adapted for slicing and shearing meat while cats have sharp incisors and canines for piercing flesh.
There has been some debate over whether or not dogs belong to the order Felidae.
Some scientists believe that they do while others maintain that they are in a separate order altogether.
The main reason for this discrepancy is that dogs have 42 chromosomes while cats have only 38.
This difference is significant enough that some scientists argue that it warrants placing dogs in a separate order.
However there are other scientists who argue that chromosome number is not a good indicator of evolutionary relatedness.
Dogs and cats both belong to the family Felidae and therefore share many common characteristics.
They both have sharp teeth and retractable claws for example.
It is likely that the two species diverged at some point in their history but there is no evidence to suggest that one belongs in a separate order from the other.
What Is Order Felidae?
Order Felidae is a taxonomic order of mammals that includes all cats.
They are characterized by their sharp incisors retractable claws and powerful jaws.
The order includes both big cats like lions and tigers as well as small cats like the domesticated house cat.
All felids are obligate carnivores meaning they require animal protein to survive.
Their diet varies depending on the species but typically includes small prey animals such as rodents rabbits and birds.
Felids have been known to kill prey much larger than themselves such as wildebeest and zebra.
The exact number of species in the order Felidae is unknown as new species are still being discovered.
At present there are 41 recognized living species in the family.
