Will follow talking of the different hobbies that your dogs can have, some of them are very funny and others not so much.
Some dogs are very scared when they hear thunder or fireworks. From nervous dogs to the most intrepid can be scared at times when the noises are very loud. They may feel cornered and want to flee from danger.
It may happen that trying to caress or contain them at that moment can make the situation worse because they feel that we are reinforcing the behavior and that, in some way, we are confirming that there is something to fear. The best thing is to continue with what we were doing and for them to feel that nothing is happening. After a while they will get used to it.
Another behavior of dogs, which becomes a habit, is roll in the dirt after bathing. This attitude is very normal. By doing so, they feel that they are camouflaging their smell with that of the environment and thus avoid being detected. They may also be marking the territory using their scent.
Many dogs they spend hours a day digging holes. Digging is part of the dog institute, as annoying as it can be. They can do it for different reasons, including: when they have to bury or unearth something, when they want to chase a guy, when they are preparing a cooler and more comfortable place.
And finally we will refer to the custom that dogs have of chase your tail. This is also quite common, When they do it very often they are looking to get your attention, they can also do it out of boredom or because they have something that bothers them in their tail or in their anus. If you want to rule out the last options, you should take him to the vet to find out what the reason for the problem is.
