Is eat() a method on Dog or $fido? Well, if eat() changes $fido's next_poop_interval property, then obviously it needs to be an instance method.
This is a great example. :-)
And of course, if your system is only every going to have 1 Dog then you don't need to ever have instances, right?
if ($Dog::is_female()) {
err on the side of caution && instantiate it nevertheless;
}
