Don't ever put GPA on a job resume. If a hiring manager wants to know your GPA, they will ask. Most jobs don't give a hoot as to what your GPA is.
For VMCAS, follow the directions. I think you have to report your cumulative GPA as it shows on your transcript from what you consider your "main" university, which is usually where you obtain or are going to school towards your bachelor's. At least, that is how I remember it being when I filled out VMCAS a few years ago. You also have to list every class you have ever taken, how many credit hours it was and what grade you received. With the classes that you are taking and retaking in the fall, you will put those in VMCAS as "in progress" classes. You do not fill out what you predict your GPA will be in the future, which is what it sounds like you are suggesting. Since fall classes won't be over until December, your vet school application will already be submitted once you get those grades. All schools require that you send in fall transcripts once they are available, so then you can send in that update. But you don't predict what your future GPA might be for the application.
