The difference in a Bulldog (French Bulldog in the Gif) and a Pit Bull...
My Pit Bull loves tennis balls. He would run through a brick wall to get the ball and would bypass food or sleep to hold onto to it when playing tug.
In his younger days when a ball would roll under the sofa, he would go under the sofa to get it to the point the sofa would be lifted off the ground (even when I was sitting on it).
He would get the ball off that sofa as shown in the Gif even if he had 4 broken legs...
When he is fixated on the ball, he will ignore all physical pain and everything else...Winning (getting the ball) is literally all that matters to him.
The Cowboys need players and coaches with that mindset.
On the flip side, my Bulldog gets bored with balls/toys very quickly. Treats, food, sleep, going for a walk are all more important than getting a ball. Bulldogs and Pit Bulls are both awesome but they have a completely different mindset.
