Canine behavior is full of curious and intriguing habits. Who has never wondered why the dog is spinning in circles before pooping? Or why these animals are so fond of rolling in the grass (and sometimes even eating it)? But among so many customs, one of the most enigmatic is why dogs smell each other when they bump into each other on walks and walks, even if they have never been on a walk.To unravel this mystery, the Paws of the House went in search of answers, and here's what we found out about it!

Dog sniffing each other's tail: understand the reasons!

Whenever a dog meets another, one of the first things he does is sniff his new friend's butt and other parts of his body. However, this is a behavior that arouses many doubts, because it is something that seems to be very intimate, right? Wrong. The reason why dogs sniff another (including in the butt area) is simple: this is a form of greeting between dogs, and thatis not related to the intimacy they have with each other.

Dogs have structures located in the rectum that are called anal glands, and they exude a very specific odor in each animal. Therefore, when we see a dog sniffing another's tail it is because he is trying to get to know the new four-legged companion better. With this, he can identify information such as: whether it is male or female, the diet that the dog follows and evenThis process also allows them to find out if they already know each other or have never bumped into each other before.

Canine behavior: the sense of smell is one of the main means of communication for dogs

The canine sense of smell is extremely powerful, and it is one of the main ways that dogs relate to the world. They have about 200 million olfactory cells, having this sense up to 40 times more refined than humans, who have only 5 million sensory cells. This means that dogs can distinguish a large amount and variety of odors to their liking.They also have what is known as "olfactory memory." In other words, dogs can store different types of smells in their heads, which can be recalled whenever the animal comes into contact with the odor in question.

So here's another answer to the question of "why does one dog smell another": dogs can recognize other puppies when they sniff their tail - the scent exhaled by the anal glands is "stored" in the animal's memory.

Dogs may not speak, but they can still communicate in many other ways. Barking, for example, is much more than just a noise that dogs make to get your attention: it is often the way your friend tries to talk to humans and other animals. Whether it is to express that they are happy, needy, sad, scared or even with a friend.Another very important point is canine body language, which includes everything from the movement of the ears to the position of the dog's tail. But remember: the analysis of the posture of the puppies should always be done together, and never in isolation. Only then can you identify what the dogs want to say.
