I was looking on my gelding's papers and notice that his granddam is a Standardbred. Maybe I have just never noticed before but I found this a bit odd. Doesn't matter - I love him regardless, just curious. I am not really familiar with Standardbreds, is this a common practice?
If he has AQHA papers I would say that allbreed is wrong. There is no way the AQHA would have aloud that. I know that when I put one of my horses in I had to select the breed of the horse I was putting in. This is because there was 2 horses with the same name but different breeds.
