What was the hardest part about becoming a Veterinarian?

You must be dedicated! Becoming a vet takes time. You're looking at 4 years to get your Bachelor's Degree plus another 4 years getting your DVM. For some it takes 9-10 years. While getting your degrees, you'll also need to volunteer/intern at animal related facilities like zoos, shelters, and vet clinics. If you want to open a private practice, you'll also need a good head for business management, or have a partner that can handle that for you. You'll also need access to funds to open up that practice.

If you're still in high school I'd suggest taking your summer to do an internship at a vet clinic. This will help you decide if being a Vet is really what you want to do. I thought I wanted to be a vet until I interned at a clinic. I couldn't handle being stuck in a building all day with just cats and dogs and sitting by watching people cry as their animals got euthanized. As a result of my vet clinic internship during high school...I decided to become a zoo keeper. In hind site, I could have combined the 2 and become a Vet at a zoo. But I also realized I wasn't cut out for 8-10 years of college and the cost associated with it.

Call around to your local vet clinics to find one that has an opening for an intern/volunteer. Vet Clinics are accustomed to this!
