A further challenge for the dog actor was to lie still in an isolation tank and not move even when petted by Bakula or Billingsley during some long scenes whilst on screen. At times a stunt dog was used, but Breezy was required for any close-ups. A Beagle prop was also created for the scenes in the isolation tank and to be submersed in a super-hydration tank. The prop was created by Joel Harlow, who had also created make-up designs for the television series "Carnivàle" and the film "The Chronicles of Riddick".
