Shulder, L., Ogbin, J. 2010. Zen Pen. Enrichment Record 5, 8.

At Huntingdon Life Sciences, we have developed a program to meet the exercise and socialization needs of our canines. Our program, entitled "Zen Pen" is a 30-minute weekly play session with at least two technicians. Four to five dogs are chosen from our in-house colony and placed in a gated hallway with a plastic play structure, a tunnel and a variety of toys. This method of enrichment allows our dogs time to socialize within a larger group, while also providing them socialization with our technicians.
