I am looking to purchase a good vet reference guide. I remember one book that was floating around the forum that people suggested to have as a good reference guide to problems with your dog. Any suggestions?
Giffin & Carlson, "Dog Owner's Home Veterinary Handbook," 3rd edition, 2000, 570+ pp, $30 list, $25 Amazon (US$). It has a useful 44 page chapter on emergencies and first aid. This book saves worry, money from vet bills, and your dog's health; it repays its price many times over. Every dog should come with one; every dog owner should refer to it whenever needed.
As good as G&C is -- and their 44 page section on emergencies is worthwhile, BUT ---
Bruce Fogle's paperback, "First Aid for Dogs: What to Do When Emergencies Happen" is far better for emergencies.* It has 197 pp, many clear, helpful line drawing illustrations, and decision trees for help deciding if you need to see a vet ASAP, look for which symptoms emerge and see within 24 hrs., etc.
The bad news is that, unfortunately, it's out of print* But the good news is that copies are still available used often for less than $10 (US) + S&H from Amazon and their secondary resellers.
