Dog doors

Petsmart sells them so go in your local store or online. I personally like the ones with the security thing that you clip on your dog's collar that unlocks the flap

That security feature will only really stop things like mice from coming into your home

For security consider putting it not on a door, but somewhere only your dog can fit in and out of that is not very obvious to a potential robber.

If you can't do that you can put the entrance at the back of a dog house so it's hidden from view and just looks like a regular dog house.

>on large dog doors set into glass windows with security panels?
You don't set them in glass panels, rather you don't cut a hole in a piece of glass then install a dog door in that. If this is a residential home you probably don't have floor to ceiling windows. If by the off chance you do, it would probably be a storefront style system. You could deglaze the window and replace it with a panel with a hole for the dog door.
Again I think your terminology is off OP. Take a picture of where you are wanting to install the dog door.
