I am sorry to hear about your puppy! These look like they could be pustules, or little pockets of infection. We can also occasionally see things like ringworm (a fungus) cause raised lesions, or foreign bodies like grass awns that migrate into the skin and cause swelling and infection. It is definitely odd! I would recommend bringing her to a veterinarian for an exam, as she may need to have the areas drained/tested and may need antibiotics to treat this.
