For the next time they bring the dogs through, save all of your seeds, stems and other scraps. Then before they bring in the dogs, steep that shit in some hot water, cool it down and spray it all fucking over your dorm building out of a squirt gun (Water from bubble hash would be even better). Couches in the lobby, fire extinguishers, trash cans... anything that will hold a smell. Carpet would be a God-Send for this. That dog won't know is head from his ass. Blind that dog and you can hide your stash a lot easier! Plus it'll be fun to watch the dogs go nuts.
