I just finished reading the book titled "Multiple Dog Households" and it WILL be very good to go by.
They have this on sale because I think it'll be discontinued. This site is selling it for $4.95 plus shipping. I paid $12.95 for it.
The book overview:
Multiple Dog Households addresses the special needs and lifestyle issues that go hand in hand with having two or more dogs in the home. From introducing a new dog or puppy into the household to the unique care and living situations required, this book will offer the reader advice on how to make the most of sharing your life with more than one dog. Also included are valuable training tips that will make daily life easier, up-to-date information on nutrition and healthcare, and activities that your whole pack can enjoy and participate in together.
