Official Explanation

Examine only the beginning and ending weights for all three animals. For the cat and hamster the difference between the original and final weights was less than 2 kg. For the dog, the initial weight was a little more than 10 kg, while the final weight was a little more than 8 kg. The dog’s weight changed by  10 – 8 = 2 kg,  which is the greatest change for the three animals.
