There are a number of dog lovers and experts who believe that dogs chase their tails for one reason. The dogs are bored. If your dogs chase their tails frequently, it may be time to provide some other amusements that will occupy the pet’s attention. OR...
A basic in the behavior pattern of many household dogs is a desire to receive attention and affection from their owners. There is a possibility that the dog has learned that when dogs chase their tails, owners pay attention and often respond by laughter. Since the behavior produces an effect that the animal finds highly desirable, the tail chasing may be repeated when the pet wants to be petted or hear a kind tone from the owner. OR...
Dogs may also choose to chase their tails because there is physical discomfort of some type. Fleas may be present on the tip or the base of the tail. It is also possible that some sort of irritation in the area of the anus is causing itching or some other form of discomfort. Dog behavior demands that the animal attempt to address the origin of the discomfort, so the chase is on. If a physical complaint is suspected of being the origin of why your dogs chase their tails, a trip to the vet will help alleviate both the activity and the suffering that causes the behavior.
