Veterinarians have discovered an interesting connection between dogs who chase their own tails and their blood cholesterol levels. In a study published in the Journal of Small Animal Practice, researchers took blood samples from 15 healthy dogs that were compulsive tail chasers, along with samples from 15 healthy dogs that did not chase their tails. When their samples were analyzed, the tail chasers were found to have significantly higher levels of blood cholesterol
Researchers theorize that cholesterol affects the cell membranes which control the flow of brain hormones. Previous studies have shown a correlation between high cholesterol levels and certain behavioral problems in humans.
