There is an absolute wealth of information to be found on this forum
http://www.game-dog.com/forum.phpyea, there are a few knuckleheads you have to weed through but I've got quite a bit of knowledge about the APBT having been around them for much of my 37 years on this earth, and there are some old time dog men who post on that forum who i've learned a thing or two from. Given that its a site about "game dogs" they can be tightlipped about some things and a bit cautious of strangers/new posters but the search function can overcome that. For the record, i've never been a dog fighter or in any way a part of that world. I just really love dogs and learning all i can about them. It's that never ending pursuit of knowledge that actually led me to this forum a few weeks ago.
