Do you follow any particular training programme with your dogs ? I just train my own way,I don't do the Dominance theory and believe the word is very overused for a poorly trained dog. My dogs are allowed on the sofa but only when we call them up,they go out through the back door before us etc. We train using positive methods,praise,reward ignore the unwanted behaviour etc. My breed can be stubborn and head strong,yet I have never felt the need to use heavy handed training methods with them,just consistant training.
