I'm looking at buying an OFRN and I was just wondering if anyone has an opinion on some of the advantages/ disadvantages with this bloodline. Also, I've noticed that their bone structure tends to be a little broader, almost bully-like. Specifically, I like the look of the dogs at aHeartofstonekennels.com. Although they claim to be selling APBT, I was wondering if someone could take a look and give me a second opinion. I do a lot of running and hiking/outdoors type stuff, so I'm looking for a super athletic dog.
