I have to agree with previous posters who recommended working at an animal shelter. I had a LOT of trouble finding a clinic to work in when I was first starting to gain vet experience. I eventually found a great animal shelter and started cleaning cages in their spay/neuter clinic. It didn't take the vet long to realize that I was good for much more than walking dogs and cleaning cages. I eventually became the shelter's only licensed tech and have gone on to get some experience at an emergency clinic, to work on the board of a different non-profit organization, to get some exposure to specialty practices, and to work with lots and lots of lab animals. All of this got kick-started by my time scooping poop in a shelter.
If you're looking for shelters, try to find one with a dedicated veterinarian who you can work with. Even if they have a part-time vet who comes in twice a week, if you get to know them, you might be able to find some time working in/shadowing them at their "regular" hospital. Also, see if you can find hospitals with boarding or grooming services - they may need more help with kennel work or desk work.
Another thing you might try is visiting a rescue that works specifically with farm animals/large animals/horses/exotics/etc. They might need help and that could open doors for you. Another poster here has shadowed a hoof trimmer for awhile and got a lot of exposure to large animal stuff that way. Something like that could be a good option for you, depending on your area.
I know you think one year is enough to get all the experience you need, but you're actually cutting it really, really close. Good luck finding someplace!
Also, please please PLEASE do NOT say something like "I changed from human med because I just couldn't deal with people as clients." or "I knew I loved medicine and I loved animals, so I just put it together!" during your interview. Unless you *want* a denial, that is... 😉
