I would take Remi into an ER vet or find a vet on call to see her now. At her age, she won't be vaccinated and her symptoms could be caused by parvovirus. Parvo is a deadly disease with no cure, only symptomatic treatment, and it requires intensive hospitalization in order to give the puppy the best chance of survival. Other causes of her symptoms include a severe GI illness, eating something rotten, and a foreign body. The vet can diagnose what is causing her symptoms and can treat her. Please take her into a vet now.
