Asked: will my dog still like my younger dog after she bit it?

my girl dog bit my 7 month old puppy today in the morning because my puppy was eating in a seperate room and my female came inside and tried fighting for his food and bit it in the cheeck area luckily i came in right when it happened and was able to pull her off of it intime before she bit it again and i left her outside and kept the puppy inside because i didint want its cuts getting infected,and now when the puppy got close to the door our female lunged at it threw the gated door,they use to be playfull with eachother and stay outside peacfully but now im scared of letting my puppy outside. and we just today started thinking she was preagnant because she was in her sycle about a month ago and she got out twice while she was in it and she is only 13 months and today we noticed she was a little chubier and her nipples where a little swollen.but we will take her to her ultrasound on friday and see if she is preagnant i just want to know how i can get my dogs back to being comfortable around each other
