Looking at buying a puppy please help find the breed I want?

Try looking at www.justdogbreeds.com I think it's the perfect website for you :-) I have had 5 German Shepherds and mixed them with various breeds BUT it depends on the character of the German Shepherd that you get (not always possible to know how they will be with other dogs until they reach around 2+ years old and mature). A breeder should be able to tell you if the mother/father has a gentle temperament and gets on with other dogs. Good luck. You sound like you are researching this properly before you take the big step :-)
