I think the main problem with bullx and feet problems stems from the fact that they are quite heavy dogs for their size. Ie, a bullx dog standing at 27" is more than likely going to be alot heavier than other x,s of this size,eg saluki/grey or collie/grey. I personally know of bullx dogs that stand at 27" and weigh in in excess of 90 to 100lb. Of course at this weight foot problems are going to occur. Also the running gait of a bullx has an adverse effect on its joints and feet. Hence the shattered and broken toes much associated with the bullx. atb stabba
