Dog door installation

Hi! i need a dog door installed in my house going out on to a patio where there is no wall for a door to go through. there is a thick glass sliding door and a section of vents that let air in. i’d like to remove the lower pannel of vents and install a dog door in that area. if that is too difficult i’m open to installing one into the glass. whichever option is the most cost efficient! i’ve attached photos of the vents. the lower pannel i want removed is approximately 30cm wide and 70cm tall. cheers would like this done asap
