Spending time with a dog can be a lot of fun for pet lovers. Dogs usually have extremely funny behaviors or attitudes, and they all have a reason.

Many of them have a scientific or veterinary explanation, while others are based mainly on the dog’s boredom or desire to play. There are some postures or attitudes that are often repeated in many dogs, among which are biting their tail, spinning around, sticking their head out of the car or shaking a toy with their mouth.

This can be quite common to see in a dog. However, as normal as it is, you should do it occasionally. According to the Hospital Veterinario del Mar, in Spain, a dog constantly trying to bite its tail can be a sign of an illness, such as the existence of external parasites or skin problems, since the dog would be trying to remove them.

It is important that if your dog repeats this behavior many times that you consult a veterinarian.

Those who have a dog will have seen him circling the place where they are going to spend the night before going to bed. According to specialists in these animals, this is an instinctive behavior, since the dog is making sure that there is no danger around.

Stick your head out of the car

Dogs usually stick their heads out the window to catch more smells.

Another thing that many dogs tend to do is stick their heads out of the car window while it is moving. This is due to the interest they have in recognizing smells and sensations in new places. A BBC study claims that the more the wind flows near a dog’s nose, the more odors they can detect.

This attitude, quite friendly, is a form of play for dogs. They pretend they captured prey and are trying to kill it. It is an instinctive behavior that should not be a cause for concern.

According to some veterinary portals, there are many reasons why dogs can howl: by imitation, to mark territory or to get attention, in case they need their owners to attend to any of their needs.
