In
a study published in Plos One named “Environmental Effects on Compulsive Tail
Chasing in Dogs” ( Tiira, et al., 2012) it is noted that Tail
Chasing is a stereotypical behavior that seems to have a higher rate of
occurrences in dogs that had experienced “lower quality care” and were
separated earlier from their mothers compared to dogs with no tail chasing. The
study revealed Dogs receiving vitamins and minerals (especially vitamin B6 and
C) chased their tails less compared to the dogs not receiving these supplements.
Another finding in this study is boredom is not
a significant cause of tail chasing, although the presence of children and/or
other dogs in the house served to reduce tail chasing. In an earlier study
conducted by Dr Nicholas Dodman and his team, discovered a spot on canine
chromosome 7 that contains the gene CDH2 (Cadherin 2). This gene was found to
be varied in dogs with compulsive disorders. ( Dodman, et al., 2010) . In an article in
the NY Times Dr. Karen L. Overall, environmental causes
might outweigh genetic factors in development of compulsive behaviors. She further
states dogs confined in kennels, shelters, and dogs from puppy mills “seem
prone” to developing compulsive disorders. (Derr, 2010) In the same article,
Dr Edward Ginns (who worked on the study with Dr Dodman) states “Although
antidepressants, particularly selective serotonin reuptake inhibitors and
clomipramine, a tricyclic antidepressant, and behavior modification have proved
effective at controlling compulsive behavior in dogs and people, they do not
appear to correct underlying pathologies or causes” He believes (in many cases)
there is an underlying genetic predisposition to compulsive disorders. It
appears that the most effective method of treating compulsive disorders is a
combination of drug and behavior modification therapies. The behavior modification
should include teaching the dog to relax in different situations
(environmental, social, etc.) and/or redirecting the dog to an activity as a
substitute for the compulsive behavior. Philip K Greis
