Let's start by finding the time it takes for the dog to reach a velocity of $4$ m/s.

We can use the following equation, where $v_i$ is initial velocity, $v_f$ is final velocity, $t$ is time, and $a$ is acceleration.

$v_f-v_i=at$

We're trying to solve for $t$ first, so divide both sides by $a$ .

$\dfrac{v_f-v_i}{a}=t$

Substitute in the known values.

$\dfrac{4-0}{10}=t$

$\dfrac{4}{10}=t$

$\dfrac{2}{5}=t$

Now, we can use the following formula to find the distance.

$s=v_it+\dfrac{1}{2}at^2$

Substitute in the known values.

$s=0*\dfrac{2}{5}+\dfrac{1}{2}*10*(\frac{2}{5})^2$

Anything multiplied by $0$ is

$s=\dfrac{1}{2}*10*(\frac{2}{5})^2$

Just simplify from there.

$s=\dfrac{1}{2}*10*\dfrac{4}{25}$

$s=5*\dfrac{4}{25}$

$s=\dfrac{20}{25}$

$s=\boxed{\dfrac{4}{5}}$
