I've not actually received any acceptances yet, but I've been invited to interview at 3/4 of the schools I've applied to thus far (and that 4th is guaranteed for IS students, so I guess technically I'm 4/4) and was recently waitlisted at one of those schools with a cumulative GPA of 3.21. That being said, my science GPA is quite a bit higher (3.4-3.7 depending on the school and which classes they factor into that), as well as my last 45 hours GPA, which is right around 3.5-3.6 range. My GRE scores were also slightly above average, and I've got ~2000 total hours of vet experience in multiple areas. I do have several hundred hours of research experience, as well. Academics are important, yes, but don't underestimate the significance of your experiences, recommendations, and personal statement, either. If your lower grades were in the non-sciences and/or are older, as was the case for me, I think you've got a much better chance than someone who consistently struggled in the pre-reqs.
A lower GPA absolutely does not mean that you have no chance for vet school; you may just have to be more selective and smart about where you apply. For example, if I had been OOS for Mizzou rather than IS, I would never have applied because they have one of the highest average accepted cumulative GPAs of all US schools, and it would've been a huge long-shot for me.
Good luck!
