Why do dogs chase their tail?

It's obvious why they do it . . . they do it because there's no other thing to do! You know, sometimes when you see dogs chasing you start asking yourself what are they thinking in. The answer to this inquiry could probably be the following: "Damn this thing, it's faster than me , but I'm still going to try to catch it." Dogs skills vary from one dog to another. Some have skills that are more developed than others mostly among untrained animals.

To tell you the truth I think dogs that chase their tail are brainless or have an epileptic-type of disorder. So if you find your dog acting as mentioned don´t hesitate and take him to the vet.
