Cd dog stud

I like to know what is in the dog's genes. The papers do not tell the whole story of the dog though. The fact that you know what the dogs before him were about and what they have produced is the same thing as having a pedigree, it just isn't written. I can look at an APBT's pedigree and have an idea of what he "should" be like but I have never seen or heard of a dog that could read so what the ped says he should do does not always hold true. I know a lot of old dog men that had hand written peds for all of their dogs. Some of them matched what was on the dog's registration papers and some did not. I was asking about bloodline because he looks a lot like some of the dogs that I have had for the last 20 years. How much does the dog weigh? Has he been bred before?
