Future Veternarian that needs help

Hi,
Im an high school student who is looking to become a veterinarian. I’m not sure what degree i should get? I thought about biology and was told tat it doesn’t offer many jobs. i than considered microbiology which i found the same thing. Should i major in a totally un-related major and minor in biology that way i can take the pre-requisite courses for Texas a&m vet school. I volunteer at the animal shelter and was wondering if that counts as experience? What should i major in just in case i don’t get into vet school i would like to have a back up. It all seems very over whelming please help. A step by step process would be nice or your personal experience
