						Pullen, A.J., Merrill, R.J.N., and Bradshaw, J.W.S. Habituation and dishabituation during object play in kennel-housed dogs. enrichment Domestic dogs are reported to show intense but transient neophilia towards novel objects. Here, we examine habituation and dishabituation to manipulable objects by kennel-housed dogs. Labrador retrievers (N = 16) were repeatedly presented with one toy for successive 30-s periods until interaction ceased.
					
									
					 
					
					
			
					
											
					
															
						In this study we have examined short-term preferences for toys with a range of characteristics, using two methods of presentation, in both long-stay dogs in complex kennels, and short-stay dogs in rehoming kennels. Our findings support previous proposals that robust toys are little used by kennel housed dogs. However, with less robust toys, interaction was relatively prolonged, indicating that interest to the dog may be enhanced if the toy can be chewed easily and/or makes a noise. Hanging toys were not favoured, although these have been reported to stimulate high levels of interaction in juvenile laboratory beagles. Pullen, A. J., Merrill, R. J. N., & Bradshaw, J. W. S.
