I dunno, maybe (probably) the other vets would disagree with me, but .... if someone asks me to shadow what I appreciate is this:
o Brevity: I don't want a 2-page letter with a 2-page resume with three letters of reference with .... Keep it simple. It's not a job, it's shadowing.
o The following info, clearly articulated: WHAT you want, WHY you are interested, WHEN you want to come/start/whatever, and something that gives me the impression you won't wreck my day.
o Flexibility: You need to roll with the punches. I may not invite you in with every client. I may call/email you and say "tomorrow isn't going to work". I may say "can you scrub in on this surgery and be an extra set of hands" or I may say "I can't have you scrub in on this procedure, sorry." If that's going to bother you, shadow elsewhere. The message here is that my patients/clients trump your shadowing and I have to consider them first, second, and third before you. It's just life. I would love to help you get experience/hours, but you aren't the focus of my day.
All the little stuff that people worry about (should I wear scrubs? should I ask questions? how often should I come?) .... none of that crap matters to me.
Things that wreck my day:
1. Shadowers who touch animals or equipment they shouldn't. I have had shadowers adjust anesthesia equipment on their own initiative. Right in front of my ECC-cert'd techs. Don't pull that crap. Even if you are positive you know what you're doing and have 750354 years of experience as a tech. If you think you see a problem, say something, but don't touch something. *I* don't even touch equipment because my techs are too smart to let me.
2. Shadows who don't know when to shut up. I love questions, and I love talking cases with shadowers. But if an animal is trying to die and we are urgently working on saving it and I've got techs doing CPR while I'm trying to shove a suction tube down the ET tube to get blood out of the lungs and my CSR is trying to get the owner on the phone to tell them what is happening ......... really craptastic time to say "So, Dr. LIS, why are you shoving that tube down the ET tube?" Don't worry, we can debrief later.
3. Shadows who give medical advice to my clients. Just don't. If you're a 4th-yr student, I'm open to having you talk to the client instead of me. But only after we chat first. Don't interrupt me or contradict me to the client. It's not an ego thing on my part, it's about delivering a consistent, less-confusing message to the client about their animal. I've had one shadower - a first year vet student - argue with me in front of the client about my diagnostic recommendations. Yeah, you don't get invited back. I am not saying my recommendations are always/necessarily the best - I'm just a dumb-ass n00b. But don't undermine me to the client because in the end that hurts the patient.
So if you can make some comments in your shadow request that give me the impression you are level-headed, mature, will be able to know when to ask questions and when to shut up, and will know not to mess with things you shouldn't ... I'm probably going to be happy to let you come shadow. It's pretty simple.
