Yes, dogs incapacitated prey with their mouths, and use their paws less.

That said, I think the bigger differences tho are momentum, distance, and turn radius. A tyranasaures head is something like 10ft off the ground. By the time it winds up and reaches the ground, the mouse would be long gone.

There are great documentary videos of large cats chasing desert rabbits that show this really well. The cats are bigger and faster and stronger, but the rabbits can turn faster.
