It’ll be too late for this year now as lambing is done in spring, but you don’t have to be anywhere near a farm to do a placement - many farmers provide free accommodation. Look at the National Sheep Association website when it opens in November time usually. I believe your experience is sufficient to apply to all the vet schools anyway (but I don’t keep up to date), but bear in mind as a vet student you can’t simply not do a placement because you’re not close to a provider - they will expect you to travel or find accommodation. I wouldn’t say more is always better, but having a good variety is - you will be learning about all the species as a student, and imo having some experience with them from placements pre vet school puts you in a better place. And seeing more means you’ll have more to talk about at interviews and forms, so imo increases your chances of getting in. As above, do think outside of the box. Stables always love extra hands, particularly riding schools. Any shelters or kennels or groomers near you? Can you fb search farms that offer accommodation for work experience? Can you stay with a family member or friend nearer to a placement provider? I would exhaust all avenues first as it’ll help you later on, and again as a vet student you simply will have to find a way anyway.
