You should go to a vet. Better safe then sorry.

Dogs are oportunistic eaters and as such will eat basically anything that looks tasty.. You said she vomited straw.. do you have a barn on your premises or nearby with tasty cowpies or horse poo... ( a delicacy for dogs).. I would call the vet.. but if she begins to eat normally or drink.. I wouldn't worry too much about it... most things pass and dogs are fairly robust animals...

She has had a couple of days to recover from an eating misadventure. If not, call the vet. You may want to review the sticky on this, https://www.askmehelpdesk.com/dogs/information-articles-our-dogs-expert-labman-53153.html#post254171

An obstructed bowel is a serious, but seldom urgent problem. I doubt waiting until today hurt anything, but if she isn't back to normal. Call the vet.
