A Final Note:
One final very important note about training: there are a lot of different training methods available...some great, some ok, some not so good. It appears to me that many authorities on dog training tend to take their views to extreme. On the positive dog training extreme...absolutely no correction, harsh voice of any kind. All positive all day (and night). Another extreme is with the dominance hierarchy people...no cuddling, no praise, the dog is not allowed on furniture, beds, certain rooms, the dog cannot go through the door first, can never win a tug of war. You must never feed the dog unless he works for the food. In addition you must always be on the alert for the dog who is about to take over the house. Then there are several other camps and variations which I do not have the time and space to go over.
While the majority of the training I do is from the positive training camp...I do occasionally borrow from the dominance hierarchy people if the situation warrents. I do occasionally correct my dogs with a strong "No" or a snap on the lead in the show ring for a distracted dog. I have had occasion to use the dominance roll, and it worked. I do strongly support positive dog training and the majority of time with the majority of dogs it is all you need. But taking it to extreme in every circumstance with every dog will severely limit what you can do, and may end up giving you an out of control dog. Start with the positive training methods, but adjust to what is needed. Consult with a trained professional if you are unsure about anything.
Ok...one more final final note: I admit, I do let my dogs win in tug of war occasionally, and I do NOT care if they preceed me out the door. I also let my dogs on the downstairs couches, and occasionally they even sleep in my bed with me!! I cuddle often with my dogs, and I have yet to have one of my dogs take over my house!
