The owners of the dog named Goose gave him a not too suitable toy, which explains the little tragedy that happened in the finale.

At first, the animal was fascinated by the given chicken egg, mistaking it for a ball, although it suspected that this ball was somehow strange. The wild jumps of Goose, who was excited, led to the expected result - the dog accidentally stepped on the egg, and it broke, leaving the protagonist of the footage completely surprised.
The audience laughed at Goose's adventures (and, of course, the eggs), and some added that the dog should be ashamed of himself for killing a baby chick that didn't hatch.
