Courseload in undergrad

How much does courseload per semester in undergrad affect your chances of getting into vet school? Like, if I have a high GPA and varied experience, will it make any difference in my chances whether I'm taking 15 or 18 credits a semester? If I took a 14 credit hour semester, do I need an 18 to make up for it? Thank you for your input.
