Question

ok, u kno how wen u start speech bubbles u hav 2 start a new line?

i.e “Oh my God!” Emma shrieked.

“I got in! I got in!” Her pet Chihuahua Natz blinked, confused. Her mother came running obviously concerned, she looked at her daughter curiously and shot her some questioning looks.

well with the next sentence (no speech marks) do i hav 2 start a new line?

Answer 1

“Oh my God!” Emma shrieked. “I got in! I got in!”

Her pet Chihuahua, Natz, blinked, confused, and Emma's mother came running over, bristling with questions. Innocent bystanders craned their necks to see what was happening but Emma was oblivious.

Answer 2

if by next sentence you mean "her pet..." then it is fine on the same line.

also, you can leave the two 'speech bubbles' on the same line if it's the same speaker.

"Oh my God," Emma shrieked. "I got in!"
