March 24, 2009 -- A team of veterinarians has found a surprising link between compulsive tail-chasing in dogs and high cholesterol, according to a study published in the March issue of the Journal of Small Animal Practice.

The finding adds to a growing body of evidence -- mostly from studies on humans -- that high cholesterol may be a marker for behavioral problems such as panic attacks and obsessive compulsive disorder, which could be expressed by frequent tail-chasing falls in dogs.

Bouts of tail-chasing can also occur after a dog experiences physical trauma, surgery or illness, noted Hasan Batmaz, a member of the Faculty of Veterinary Medicine at Turkey's University of Uludag, who conducted the study along with a team of colleagues.
