My dd is finishing her first year of vet school. She is loving vet school. She has always wanted to be a vet and she worked as a vet assistant for two years before she started vet school, so she knows what she is getting in to. In her experience, working with pet owners for the above-mentioned reasons, especially those mentioned by @Pawz4me is the most stressful part of the job. Her vet hospital is corporate owned, and she didn't like many of their business practices, but owning your own vet clinic comes with its own set of financial stresses.
