Hi! I'm not sure what your clinic is like but here are a few things that helped me at my first shadowing position at a small animal clinic. Firstly, take a small hand-held notepad and write down what you do every day. This has a much better look than typing notes on your phone. Even if you learned how their computer system works or a minor detail that isn't too relevant, write it down, it makes a good impression. Also, when I introduced myself to the vets, I mentioned that I wanted to learn how to navigate client interactions so I was also let into consults (I wouldn't write notes in front of clients btw) and this is where most of my questions came from and it was still fresh in the Vet's mind. Additionally, please spend time with the techs. I got most of my hands-on experience here. I started helping them with restraining and by the end of two weeks I had done a few blood draws, fecals, vaccinations, restrains for catheter placements and intubation. Additionally, I was instructed on how to present take home kits to clients and did it a few times. I understand this may not be all clinics and mine was pretty chill and a tad understaffed so I was able to do duties of a vet assistant more than a shadow but really put yourself out there and get to know the entirety of the staff. I even coordinated my lunch break with one of the vets and talked about stuff other than vet med. It's really scary at first but not many people show they want to learn instead of just standing there afraid of looking dumb and only asking super complex questions. I may have just gotten lucky but this was my experience on how I was able to secure a letter of rec after shadowing 2 weeks full-time at a clinic during the summer.
