Answer 1

Thank you for the question!
We find eggs of birds in the market not of the dogs, this is because dog is a mammal and they don't lay eggs. Instead, mammals give birth to a young one through fertilization.All the fertilization takes place inside the female dog. While on contrary, birds are oviparous and lay eggs.
