This is from the show The Mandalorian. IIRC, Mando is transporting this reptilian female alien and her unfertilized eggs back to her husband so he can fertilize them and continue their family line.

The “weird green dog” refers to Baby Yoda (Grogu), who shows intelligence similar to a human toddler and eats several of the eggs throughout the episode.

This is played for laughs in the episode despite being pretty fucked up when you think about it.
