I added a 3rd dog to the house. I don't want these dogs fighting over stuff. How do I do this? What collar is best to ensure it doesn't slip off a dog's head?

Hi,

I recently added a third dog to my household. I wanted to ask a few questions about pack leaders. I will be purchasing your video for additional help. I watched your video on the web with the puppies. I was amazed at how such young dogs try to establish rank. Now that I have three dogs I really want to continue to maintain my position as pack leader. I know the importance of it. I think I am doing a decent job, but there are things I can improve on. So my first question is, my two dogs that I already have in the household seems to be competing for rank. The new third dog is very submission and does not engage in any such activity, will not get into it with the other dogs in fact will run the other way. He was a rescue and I dont think he was around or lived with any dogs - this behavior is new to him. But that's not to say it wont come out down the line. I've had issue where these two dogs have fought over a toy, bone or food. I am always able to take the item away and break up the fight, but how do I handle this? I obviously don't want these two dogs fighting over stuff, is it something they have to workout themselves? do I not give them toys or feed them together? I only offer "my" toys to them, they don't have toys available to them. Not sure the best approach.

With regard to the new dog, he was basic obedience trained, but is very rusty. I need to work with him. He is a pug/boston terrier mix. The previous owners apparently walked him using a harness, which I don't really like, but he walks well on a leash. But for training purposes I think a collar is better. Problem is that due to his mix breed he basically has no neck, so collar easily slips off him. What collar is best to to ensure it wont slip off his head? I've heard that a martingale might work. You have several available on your web site what would you recommend. thanks
