You probably already know everything I'm going to say, but I'll try to answer your question as thoroughly as possible.
There is defiantly hope for you getting in somewhere at some point. For this year? It all depends. What schools did you apply to, if I may ask? It all depends on a lot of variables. You *may* get an interview some places with those stats, or you may not. A lot of people on this board have gotten in with one or more sticking points on their application, and/or after improvement over the course for 2 or more years of application. If you applied to Western I'd be surprised if you were not interviewed, from my experiences last year. On the other hand I'd be surprised if you were interviewed at NC State or accepted to Cornell. Your essays and LOR also make a big difference to some but not all schools.
It depends on how much you want it and what you are willing to do to get there. You CAN get that GRE score up. Vocabulary is built slowly and the test screens for a large and varied vocab. The best verbal section test takers are those people who have read everything they could get their hands on for a long time. You can spend the next six months reading, studying, learning words by context and by definition group. If you already know how the questions are asked and some basic test taking skills then building you vocab is your best option. Cramming almost never works (not saying you did cram).
You can go back and get your CUM GPA up. Take one or two classes, preferably upper level bio classes that will count toward pre-reqs you don't have. I was a double major too and I had to choose between cell bio and biochem one year. Now I could go back and take cell bio and open up more schools/ show I am capable of upper level bio classes. Or if there was one class you got a C, C+, B- in or was significantly lower than most of your pre-req classes re-take it and rock it. Two classes a semester and two over the summer (which is about 1/2 time school) will equal six classes by next cycle and could raise your GPA by .1 give or take depending on how many credit you have already and what you get in the classes. 3.35 vs 3.45 is the difference between being *under* the mean *almost* at the mean for some schools.
You could get more varied experience. If you have lots of hours (500 or more is lots to me). Then go volunteer or get a job with exotics, production, shelter, research or wildlife. For exotics go to a zoo, or to a SA practice that sees exotics, production go for chickens or pigs or cows to vary your LA exp. Shelter I found was the easiest volunteer position to find, but no paid positions available. Wildlife don't just think about re-hab, though it's a great thing to do, call fish and game in your state/ near by states and find out if they are doing and research in the area. NW NJ does study on black bears your can volunteer for in fall and spring. Research can be done at a teaching hosp or a biomed lab etc. If I could do it all over again I'd shoot for 500 hours in each area and them move on to another. I stuck myself in one practice (mainly) for over 3000hrs and I now have great knowledge about SA practice both the med and the business, but it did not help with getting in. Some schools, Tufts being one, will take into account supplemental info you send them after the deadline but before decisions are made. So you can up your GRE, and/or GPA, and/or get different experiences and have it count toward this year's cycle.
It depends on how far and where you are willing to go. If you are on the east coast then the schools in the UK are just about as far away as Davis and Western. An avma accredited school abroad may be a good option for you. There are schools in Oceana too, Sydney, Murdoch, and Massey. It is not easier to get into these programs because they are less strenuous or give you less of an education; that's what avma accreditation means, you get the same or better education. What happens is that students in other countries have less ability to get experience so American and Canadian students look great on that front. Further, the educational systems are a little different. They go to HS a year longer and then go right into professional school. So 1st year vet students are ~19 yrs old with no college education. Therefore vet school is 5 years long. Usually the 1st year is basic bio classes we take as pre-reqs in undergrad, then years 2-5 are like vet school in the US or Canada. Some schools break it up a little different. Most of these schools offer advanced placement for students with pre-reqs so you may be able to have 1 or 2 semesters of the 1st year waived. So again we look good because we have more educational experience. Here is a link to all of the accredited schools

I am starting in Murdoch in July :-D and could not be happier. The other great thing about the schools in NZ and Australia is that they have independent applications and multiple deadlines. So, you can apply there now for some on Jan 1st for the others and have them as a back up if you choose to. If you have anymore questions about Murdoch I have some more info, but you didn't ask for it originally so I won't lengthen my post any more.
Finally you could apply to Ross or SGU where you would most certainly get in (from what I understand). As non accredited schools you would face a lot more trouble and expense to come back to the US to practice. For me they would have been a very last resort, and I think you have a lot of options without dealing with a non-accredited school.
Any one improvement or applying to other schools could open your options up. I know last year the wait was horrid and I could have kept myself buisier and happier by improving my appication. I'm not saying you should, just that was my experience. Good Luck!
*whew* that was a long post.

Just looking for a little hope or maybe a reality ck:my stats are CumGPA 3.35 from Tier 1 college/major dual bio & math;numerous honors & awards, science GPA 3.4; final GPA 3.7;lots of hrs.exp @ sm.animal/exotic clinic + lots of hrs @ equine practice;competive rider 15yrs exp.; GRE 1170 (Q720/V450(boohoo) Is there any hope for me??
Since you're out of school now, don't worry about the GPA too much; I thought you were still in undergrad when I said that... it's not BAD by any means, just a little weak compared to your competition. I would suggest taking the GRE again as you've said, but then hold off on taking it a 3rd time until you hear something about interviews.
