be careful with the "defiant" label, dogs do not process emotions the same as humans. it sounds to me as tho he has had ENOUGH of the crate. crates are such an invaluable tool, but in a case like this, where a dog has basically been abused with confinement in a crate for way, way, way too long (before you got him), it is possible (I think), that he will never accept a crate. just went back and looked at your post, you've only had this poor guy eight weeks and he's had an entire prior lifetime of brain conditioning to absolutely HATE being crated. I think this will take a very long time, and it's likely a matter of trust, because it's not defiance. I am for sure not a training expert, but have a lifetime of experience with this breed. you will have to have more patience than you think you can dredge up to make this boy understand that you're not going to crate him up and leave him. please don't give up on him, i'm sure more training/behavioral tips will be coming. and you might want to consult with a behaviorist, which is different from a trainer. wishing you the best of luck, because re-homing this dog once again would be terrible for him, and ultimately down the line he would likely wind up in bad hands, since the fighters and bundlers are always looking for dogs with behavioral issues. if you can't fix it it would be much kinder to him to send him to the bridge with love, rather than pass the problem on and take a chance that he will meet with unsavory ends. wishing you much luck and sending a bit of extra patience energy to you. take care.
