Resource guarding in dogs (Proceedings)


CVC IN KANSAS CITY PROCEEDINGS


The Focus of the Discussion

• Which individual in a dyad (pair of animals) is considered to be dominant in the relationship?
• What criteria is used to make that determination (acquisition of resource vs. defense of resource)?
• Does aggression over the control of resources equate with dominance based aggression?

"Dominance: the assertion of one member of a group over another in acquiring access to a piece of food, a mate, a place to display, a sleeping site or any other requisite that adds to the genetic fitness of the dominant individual..."
E.O. Wilson from Sociobiology: The New Synthesis, Belknap Press of Harvard University Press, 1975. pg 257

Resource holding potential

     › "......examples of "aggressiveness" are far more likely to represent long-term differences in subjective resource value."
       Hurd PL. "Resource holding potential, subjective resource value, and game theoretical models of aggressiveness signaling." J Theor Biol. 2006 Aug 7;241(3):639-48. Epub 2006 Feb 9
     › "Dominance is a concept found in traditional ethology that pertains to an individual's ability, generally under controlled conditions, to maintain or regulate access to some resource."
       Karen Overall ("Clinical Behavioral Medicine for Small Animals" Mosby 1997. pg. 115
     › "Relative dominance is usually tested by giving two dogs access to one bone. The dog that gets possession is considered the higher-ranking dog."
       Katherine Houpt ("Domestic Animal Behavior for Veterinarians and Animal Scientists" Iowa State U. Press 1982 pg 65)
     › "...a single bone was brought in, shown to the puppies, and laid between them...."
     › "...we defined a completely dominant animal as one that kept possession of the bone the majority of the time and was able to repossess it at will."
       John Paul Scott and John L. Fuller ("Dog Behavior: The Genetic Basis" The University of Chicago Press 1965 pg. 156)
     › "The dominant dog shows a self-assured gait, a large, confident body posture, raised head, raised ears, large eyes and curled lips, all in different intensities and combinations depending upon the degree of dominance, superiority, or self-confidence."
       Roger Abrantes ("Dog Language" Wakan Tanka Publishers 1997 pg. 93)
     › "...Once everyone knows his place, the alpha male need only move toward a lower-ranking male to have that individual hurry out of the way or otherwise signal submissiveness..."
       John Alcock ("Animal Behavior" Sinauer Associates, Inc. Publishers 2005 pg. 332)
     › "In equal opportunity tests (EO tests), both members of a pair had equal chance to seize the bone when it was tossed into the arena"
       Beach, Beuhler and Dunbar ("Competitive behavior in male, female, and pseudohermaphroditic female dogs." J Comp Physiol Psychol. 1982 Dec;96(6):855-74) Equal Opportunity Tests (EO Tests)
     › "During an EP test, the loser of the preceding EO test was given possession of the bone before the former winner was returned to the test arena"
       Beach, Beuhler and Dunbar ("Competitive behavior in male, female, and pseudohermaphroditic female dogs." J Comp Physiol Psychol. 1982 Dec;96(6):855-74 Established Possession Tests (EP Tests)
     › "...for a meaningful formal test of dominance, and to rule out differential motivation as a confounding factor contaminating the results, both animals must be motivated equally for the same resource."
       Wendy van Kerkhove ("A Fresh Look at the Wolf-Pack Theory of Companion-Animal Dog Social Behavior" JOURNAL OF APPLIED ANIMAL WELFARE SCIENCE, 7(4), 279–285)
     › "A reasonable hypothesis is that the physical restrictions and limitations of captivity define environmental circumstances, engendering the formation of dominance hierarchies in wolves. Much the same might be said for dogs living together in a household."
       Wendy van Kerkhove ("A Fresh Look at the Wolf-Pack Theory of Companion-Animal Dog Social Behavior" JOURNAL OF APPLIED ANIMAL WELFARE SCIENCE, 7(4), 279–285)
