Buy your girlfriend a dog, split the vet and food costs, and both of you go to training classes together. You can handle the dog during class and both of you will need to practice your weekly lessons with the dog every day separately. You both need to be on the same page, doing things the same way, just like raising a child.
My recommendation, as a wise woman who has a lot of living under her studded belt, is not to do this at all and wait until you get out of college and have a good job at the very least. Probably wait until your single years are over too, unless those won't be over until your 30s. Think of the mess you'll have if you break up with this girl and think of this for the dog's sake!
