Your view code:

def Mascota_View(request):
    if request.method == 'POST':
        form = MascotaForm(request.POST)
        if form.is_valid():
            form.save()
            return redirect('index')
        else:
            form = MascotaForm()
        return render(request, 'mascota/mascota_form.html', {'form': request(form)})

Notice that it only returns render(......) if request.method == 'POST'.

What does this function do for GET requests? It returns None because
execution falls off the bottom of the function. You need to return a
suitable response or raise a suitable exception.

Notice that your test is using a GET method, not a POST:

# ValueError at /mascota/crear/
The view Refugio.mascota.views.Mascota_View didn't return an 
HttpResponse object. It returned None instead.
