Investigating the Solidity Principle in Domestic Dogs (Canis lupus familiaris)
The solidity principle (SP) dictates that solid objects cannot pass through each other or exist in the same location. Investigations in human and nonhuman primates have demonstrated that they understand SP, and suggested it may be central to navigating the environment. Research in canines has been i...

The solidity principle (SP) dictates that solid objects cannot pass through each other or exist in the same location. Investigations in human and nonhuman primates have demonstrated that they understand SP, and suggested it may be central to navigating the environment. Research in canines has been inconclusive.
