I have a daughter who is currently studying in a DVM program, and another daughter who is currently doing microbiology/medical research as her first job after graduating university. Thus I have some experience related to this.
Premed classes and pre-vet classes overlap quite a bit. My older daughter (the DVM student) knew several premed students when she was an undergraduate student specifically because they were in many of the same classes. However, she also had a small number of classes such as “lameness in horses” that was clearly a pre-vet class and NOT a premed class.
Your daughter might want to talk to admissions at a few DVM programs and see whether they think that her classes already taken are a good complete set. She might want to take a few additional classes to get a bit more animal experience.
This sounds like a good plan. Getting relevant experience sounds like it is the most important area for her to catch up. It might take more than a year. She might want to try to get some large animal experience (horses, cows, …) in additional to small animal experience. She will also want some experience specifically in a veterinary situation. She will want to work with one or more veterinarians.
My daughter did quite well in applying to DVM programs. We both think that the main reason for this was not her GPA nor her GRE scores (all of which were relatively good, although she definitely did not have a 4.0). What my daughter and I think got her accepted was her experience working with animals – both large ones and small ones, and the associated references (some of which were from veterinarians). She had thousands of hours of experience working in a range of situations. Cleaning up after cows and horses, reaching inside a cow (several different ways), drawing blood from cows and horses and giving shots, helping out with surgeries on animals, helping out in emergency situations, all of this helped. Dealing with dying animals and their distraught humans also was a valuable experience.
Some things that you will learn from working with a veterinarian: Frequently animals cannot be saved. Sometimes they bite you or kick you or step on you. Sometimes you get rather yucky.
Many DVM students took some time off between getting their bachelor’s and starting in a DVM program. This is common. There are DVM students who are already at least in their 30’s.
Finances are important. A DVM program is about as expensive as an MD program. However, being a veterinarian does not pay as well as being a doctor, and even doctor’s have some difficulty paying off their student loans. It is very important for a DVM student to minimize their debt as much as they can. If you can graduate with a DVM and no debt then the pay is entirely decent. However, if you are $300,000 or more in debt then a veterinarian’s salary will make it tough to get by.
I agree with a lot of what @saillakeerie said above. I found myself saying “yes” to myself multiple times reading their post.
