The Question

“My dog has this hilarious yet somewhat concerning habit of chasing his own tail, especially when we have guests over. It’s cute at first, but he’ll spin around in circles for minutes on end, and sometimes he even barks at his tail and gets so intense about it we have to remove him from the room to snap him out of it. I can’t tell if he’s just bored, attention seeking, or if he’s trying to entertain himself. Is there something behind this ‘tail-chasing mania,’ and should I be worried, or is it harmless?” – Dale

Hi Dale!

By the way you describe this as hilarious first, I think there is a possibility that Hal got reinforced for chasing his tail in the past. If you think about it from his perspective, visitors come in and remove his human’s attention from him. Tail chasing may have started as a way to deal with the anxiety, and then Hal learned that if he chases his tail, he can have his human and his visitors’ attention and laughs.

It is possible that visitors are his cue. You should start to use positive reinforcement techniques to teach Hal how to be calm with or without visitors. If you are willing to you may even teach him a few tricks to impress your visitors in a more positive way. After all, it sounds like he loves to be the star of the show!

Best wishes!
