Have you got more than one dog??
Do you feel like you are forever having to seperate your dogs due to fighting, or that one is "bullying" the other,
Have you just taken on two new puppies, from the same litter and are worried about training?
Has time prevented you from putting in some important training, and you had hoped that your "older" dog would train the "younger" dog,
Remember dogs do learn from each other, but not only good behaviours but also bad ones too!!!
Do you have a chorus of barking when the postman delivers, and are now dreading anyone coming to the door because of the noise?
