In this case, put the Pipolino® in a rectangular or cylindrical container of sufficient size for the dog to roll the Pipolino® in it without taking it out:
- rectangular container:
- width ≥ length of Pipolino®
- length ≥ 2 times the length of Pipolino®
- container height ≥ 3/4 of the Pipolino® diameter
- cylindrical container
- diameter ≥ 1.5 times the length of the Pipolino
- height ≥ 3/4 of the Pipolino diameter
After a few weeks you can offer the Pipolino® out of the tank again to see that it has settled down.
