I guess I should add that he does have what I would describe as an extra pad on one of his feet. Only thing I can think is maybe it's bothering him. Doesn't seem to though. No limping or favoring that foot. Doesn't lick at it or flinch when messing with it. But that's the only thing I can come up with why he would be so against walks. Every other dog I have ever had, including 4 bulldogs, have loved going for walks or rides. Not whopper.
