Seeking a second opinion can be a useful step in making a decision about euthanasia. A different veterinarian may offer alternative treatment options or provide additional information about your pet's condition that can help you make a more informed decision. However, it's important to remember that there may be financial and time constraints that prevent you from seeking a second opinion. Ultimately, the decision to euthanize is a difficult one that should be made with careful consideration and consultation with your veterinarian.
