Are Dogs Mammals?
The simple answer to this question is yes!
Dogs are mammals; they share a lot of traits with mammals.
Dogs have a long history dating back to times when humans were not so modern.
Humans have a long deep relation with dogs.
In addition, humans and dogs share mammalian traits.
All mammals have a particular set of characteristics that make it easy for us to identify them.
You can identify a mammal by observing some physical and behavioral traits.
Let us see what mammalian features you can observe in your furry friend if you still do not fully believe him to be a mammal.
Dogs Have Live Babies
Like all other mammals, they give birth to a live young one.
You can compare it with birds who hatch eggs to give birth to their young ones.
Dogs are placental mammals, and therefore they keep their baby inside the womb for gestation.
Their young ones are helpless, and they need their mother to provide nutrition and care for some weeks.
Dogs Have Body hair
Hair is another characteristic feature of mammals. Dogs possess body hair like all other mammals.
Depending on breeds, hairs can be short or long, curly or straight. In addition, dogs grow hairy coats for a specific purpose.
Some dogs have a hairy coat for purpose hunting, while other dogs have a waterproof coat.
Dogs Have a Single-Bone Lower Jaw
The characteristic feature of mammals is their lower jaw.
The lower jaw in mammals is made of a single bone attached to the skull, which gives it maximum strength.
Dogs are carnivores, and the strength of the lower jaw enables them to tear, bite and chew.
Therefore, proper training of dogs is essential to ensure they don’t bite household items.
You should also protect yourself from dog bites; otherwise, you will face serious injury.
In addition to these features, mammals possess a four-chambered heart, so do dogs.
It enables efficient pumping of blood and transportation of oxygenated and deoxygenated blood separately.
Dogs Are Warm-Blooded
Dogs are warm-blooded animals which means they can regulate their temperature with respect to outside surroundings.
Unlike reptiles, they don’t need external heat to perform physiological functions; instead, they can produce their heat.
They can upregulate and downregulate their body temperature whenever they need it.
Dogs Have Teeth
Like other mammals, dogs don’t continuously replace their teeth.
They have two sets of teeth throughout life.
The first set of teeth is deciduous or milk teeth which start falling around the 12th week.
And by the end of six months, they have a full set of permanent teeth.
These features and several others confirm that dogs are mammals.
