I remember ke= 1/2mv^2 from my physics at school

kinetic energy is half (mass * velocity squared)

(mass in kilos, velocity in m/s - if you want the answer in Joules)

Of course Einstein came along and messed all this up - better hope your dog never gets near to lightspeed - it's not Krypto or anything, is it?
