Hi! Not sure if your daughter is still looking for work experience, but here is my experience of this and some advice that I hope will be helpful in some way.
I was also looking for veterinary work experience in the summer last year (2023), and I still am, and it took me months to find any. I kept a list of all the practices I'd contacted, so as not to call or email twice, and it didn't fit on a single piece of paper, that's how many I contacted. I started with emailing them, I waited 5 days and then phoned them if I didn't hear anything. I'm not great using the phone so I wrote out what to say, eg. "my name is xxx and I emailed you a few days ago asking about work experience, and I was just wondering if there is someone I could speak to about that?" When I phoned them, they usually had a good reason for not responding, eg. short staffed etc. But they didn't all get back in touch or answer the phone, and one of the clinics took 5 months to respond to my email.
So if you don't hear from anyone straight away, just phone after a few days and see what they say. It sometimes helps if you say how long you've been searching for a placement and how many 'nos' you've gotten as they might feel a bit sorry for you. If you have any reference letters from previous placements, it's a good idea to attach those in the email.
However after contacting at least 20 clinics, I finally found one that would take me. I was lucky that they took under 16s for work experience, as none of the other clinics did (in fact some were 18+). There was a limit to what I could do, I wasn't able to be in the same room as any anaesthetics (after I turn 16 I can be though), and obviously no x rays. But I loved it and it made all the searching worthwhile.
And if you find one clinic that will take you, they often say you can come back any time. I did a few weeks at the one I found and now they've booked me in again for a couple months (just 2 days a week though).
Hope that helps, you just have to keep trying and don't lose hope, there will be one out there that accepts people! It's often the last one on your list that's the one 😃
