A horse has much more momentum than a dog, when running at the same velocity.

Explanation:

Momentum is defined as the product of a body's mass and its velocity.

We can assume a horse weighs 500kg while a dog weighs 5kg.

We also assume both animals are travelling at a velocity of #5 ms^-1#

Momentum(horse) #= 500 * 5 = 2500 kgms^-1#
Momentum(dog) #= 5 * 5 = 25 kgms^-1#

In this case, the horse has 100 times the amount of momentum of the dog.

Thus, a horse has a much larger momentum than a dog, when running at the same velocities.
