Ok....all this reading about different lines and pedigrees got me to take mine out and really look at it closely.  I know a lot about dogs, but not as much as I would like about lines breeding etc.  I feel as a dog owner I want to better understand these thinsg so I continue to know how to research my future pups etc. and know what I have.  I do not know too much about line breeding.  I looked at Jackson's pedigree and see that one dog actually appears twice on my dogs pedigree.   Once as his grandfather's, mother's father and once as his great great gradfather.The dog is the Hillhaven's Hustler (http://www.awesomegsps.com/hustler.htm) 

It seems this would be the type of dog you would want to use in your line sto enhance the quality of teh breed but how do you know how to read your pedigree so that it is done correctly and not considered inbreeding?  I hate to sound ingnorant, but would love some clarification   Other than that dog I do not see any repeats on his line (some from the same breeder, but not that same dog)
