Yes in fact all mammals have belly buttons which is super fascinating but they are straight unlike our human belly buttons!
In the egg there is a cord that attaches the developing embryo to the yolk sac. When the bird hatches, there is a residual scar where the cord used to be. While the bird is a nestling, you can still see what would be the avian equivalent of a belly button. However, as the bird develops, that area becomes more compact and in an adult bird there is virtually nothing to be seen of what once was the scar. So technically baby birds have belly buttons, but unlike the belly buttons of humans, these go away as they grow up.
Oh, but they do have belly buttons.
AnswerDogs do have bellybuttons, but they aren't "innies" or "outies." Only a scar is present. The umbilical cord experiences avulsion during birth; it's not cut and tied like human babies' are.They do have belly buttons. My Boston terrier has a HUGE belly button!!!!! he doesn't have fur on his belly, where most dogs do have fur on there bellies. All dogs have belly buttons.
Yes! all mammals have belly buttons. When we are growing in our mothers belly we are joint by an umbilical cord then when we have been born the umbilical cord gets cut and that is why we have belly buttons.
No. Belly buttons are part of human bodies, and as such, do not grow on trees.
