React, Django: Sending a PUT request to update data for one of my models but I get an error that a couple fields are required

Sending a PUT request to update data for one of my models but I get an error that a two fields are required even though they are set to blank=True and null=True in my model. When I create it works fine, it is just update. Maybe it has to do with using generic views? Using the same form in React for creating a pet and updating a pet information:

    export const UpdatePetInfo = async (petId, petInfo) => {
  try {
    const res = await Client.put(`pets/${petId}`, petInfo)
    console.log(res)
    return res.data
  } catch (error) {
    throw error
  }
}


const handleSubmit = async (e) => {
    e.preventDefault()
    if (editPetForm) {
      console.log(selectedPet)
      console.log(editPetForm)
      await UpdatePetInfo(selectedPet.id, {
        name: formValues.name,
        animal_group: formValues.animal_group,
        animal_kind: formValues.animal_kind,
        dob: formValues.dob,
        gotcha_date: formValues.gotcha_date,
        age: formValues.age,
        user_id: user.id
      })
      navigate(`/dash/${selectedPet.id}`)
    } else {
      await CreatePet({
        name: formValues.name,
        animal_group: formValues.animal_group,
        animal_kind: formValues.animal_kind,
        dob: formValues.dob,
        gotcha_date: formValues.gotcha_date,
        age: formValues.age,
        user_id: user.id
      })
      // Redirects user to login
      navigate('/pets')
    }
    // Resets the form to blank once API req completes successfully
    setFormValues({
      name: '',
      animal_group: '',
      animal_kind: '',
      dob: '',
      gotcha_date: '',
      age: ''
    })
    setEditPetForm(false)
  }`

models.py

class Pet(models.Model):
    GROUP_CHOICES = (
        ('Mammal', 'Mammal'),
        ('Bird', 'Bird'),
        ('Fish', 'Fish'),
        ('Reptile', 'Reptile'),
        ('Amphibian', 'Amphibian'),
        ('Other', 'Other')
    )
    user = models.ForeignKey(
        User, on_delete=models.CASCADE, related_name='pets')
    name = models.CharField(max_length=100)
    animal_group = models.CharField(max_length=100, choices=GROUP_CHOICES)
    animal_kind = models.CharField(max_length=100)
    dob = models.DateField(help_text='<em>YYYY-MM-DD</em>',
                           blank=True, verbose_name='DOB', null=True)
    gotcha_date = models.DateField(help_text='<em>YYYY-MM-DD</em>')
    age = models.PositiveIntegerField(blank=True, null=True)
    
    def __str__(self):
        return self.name

views.py

class PetDetail(generics.RetrieveUpdateDestroyAPIView):
    queryset = Pet.objects.all()
    serializer_class = PetSerializer

Using react for front end and django rest framework for backend. Please let me know if there is anything I may have missed help solve this issue. I am pretty beginner at coding, I appreciate any help!

Thank you!
