It depends on the dog. Riley was never allowed to correct anyone because he took it too far. With Zena correcting, it really depended on WHO she was correcting whether she was allowed to correct or not. Shasta isn't big on correcting but when she does, she does so appropriately. It really depends on the dog.
The more people I meet and talk to,the more I love my dogs and their intelligence.
