Okay so i have a dog, who is around thirteen or fourteen. I know she has allergies, and some arthritis, but is not taking medicine for either. Today, she threw up all over the house, and she wont eat or drink. I even tried giving her regular food, but she wont take anything. I’m really worried, shes my best friend. If i need to go the vet, I’m going to have to convince my parents to take her. So any ideas or advice would be hugely appreciated.
