How would a “corgi-sized” meteor have a mass comparable to “four baby elephants”?

OK. Assuming the corgi is 60cm long, and assuming with “size” they think of “a sphere with a diameter of”, we get a volume of 113000cm³. Depending on the weight of a baby elephant (90-120kg) we get 360 to 480 kilograms. Divided by the volume, we get a medium density between 3.1 and 4.2 g/cm³. According to Engineering Toolbox, this is about as dense as garnet or aluminium oxide, common types of stone.

If they took the height of the corgi (30cm) as a base of their spheres’ diameter, the volume is down to ~14000cm³, leading to densities between 25.7 and 34.2 g/cm³. Now that would be interesting, because that would even surpass uranium (which has 19.something g/cm³).

So depending on how to interpret those measures, it’ll be a ball of dirt, or a serious nuclear threat. That’s why scientists use metric…
