they are many (google it) but i think that this guys http://falawoods.com/contenderamericanbulldogs.phtml is good. for sure he is very ready to answer all your questions (he has done it with me)

Here are links to a few kennels that I would buy an AB from. This first kennel is basically the modern continuation of the Painter line of dogs. http://groups.msn.com/AlaskasScreamingEagleAmericanBulldogs/_homepage.msnw?pgmarket=en-us This is Don Matthews kennel, he breeds working catch dogs of the standard type. http://www.konfederatekennels.homestead.com/index.html Boyd's is the kennel my next dog is going to come from. http://www.boydsbulldogs.com/

Boyd's dogs are Excellent. Bulldogs earning Shutzhund titles is extremely impressive. No offence but any bulldog will catch or at least try to and most will be happy to take on a sleeve. However, a bulldog that can do OB off lead with another dog on field, a bulldog that can footstep track...that is just outstanding!!!!

hog hunters are always good sources for bulldogs & related etc...cuz most that i know...if that dog can't/won't work...the dog just don't got it...then its culled...or never bred...so only the best/strong survive pretty much...otherwise it ain't worth feedin...
