I had a tail chaser, so I feel I also have knowledge when it comes to this Problem, I mean no disrespect to Syd, but I "sometimes" wonder if it could also be environmental, when I got my tail chaser he was 20 Months old, and a kennel dog, I made him a house dog and he only chased his tail when he was left outside unattended, (bored? maybe?) & Never in the house. but as Syd said he never completely stopped. The product that I used on him was called 3 No Bite Spray made by Vedco. Worked like a charm, but you had to use it faithfully. You can get this thru any Vet. I showed him to: 3 Championship titles and 6 Working titles and he also assisted my daughter to 10 Best Junior handlers in Show. He was one of the best dogs I ever had the HONOR to own.

It is not from boredom, etc. I think that after 30 years I know something about the breed.
