I do not think that anyone can answer this other than yourself. We can provide some things to think about.
I probably should remember this from previous threads. However, since I have forgotten, what is your current situation? Are you about to start university, or are you currently part way through undergraduate study? If yes to either, then you still have a lot of time to think about this.
One thing that I have noticed is that getting a doctorate, one doctorate, whether DVM, PhD, MD, or something else, is a long path that requires a lot of time, a lot of effort, and a lot of determination. You need to want to do it to just get one doctorate. Two I expect would take longer and require more effort.
Our daughter who got her DVM this past May is a very determined and very driven person. She found the path to be challenging at multiple levels. As one example many years ago she told me that undergraduate organic chemistry was “the most difficult B- that I ever had in my life”. More recently she told me that the classes in her DVM program were on average just as tough. It took a lot of work over a long time period to get through these.
As another example, during the first three years of her DVM program she also had a part time job at a drop in animal clinic on campus. Some friends asked her how she could possibly do this due to the time commitment. She felt that she needed to do this in order to stay sane and to keep her mind focused on practical veterinary medicine, which is what she wants to do (and of course is doing now). One day at the drop in clinic every animal that she saw died except for one small pet rat (which had pink eye and was basically fine). The animals that died included two beautiful horses with colic (which can be messy to try to treat, and which can be deadly for horses). The next day another beautiful horse came in with colic. It was very unclear for perhaps the first two hours whether they could save it. In the end they did save it and this third horse left in much better shape. Then she got to go back to studying for classes.
When I attended the DVM graduation ceremony and related party this past May, the graduating DVMs that I met were of course all very happy to be graduating. I am pretty sure that all had jobs lined up (or fellowships or something else positive). However, some of them also appeared to be tired and near the end of their ability to put in so much continued effort. They had all put in a huge amount of effort to get the one doctorate. Three months later my daughter is way more relaxed and loves her job, but I do not think that even she would have had the energy to continue on to get another doctorate.
My other daughter right now is studying for a PhD in a different biomedical field. She has a lot of research related lab work, and apparently not many classes. She seems to be taking this as an interesting job that is challenging and gives her the opportunity to learn quite a bit, including different things you can do in the lab. She understands that this is going to go on for a while, multiple years. Perhaps this is the way to approach a PhD.
One issue with research is that “you might fail” (“You might fail” is a definition of “research” that I first heard from an MIT researcher). It is perfectly normal for someone involved in research to fail many times for a few years before they either succeed, or try something different, or give up.
The good news is that a PhD is typically fully funded. While the stipend may be just enough to live on, at least the cash flow is from university to student rather than vice versa. A small amount of help from a parent (with emphasis on “small”) can help turn this into pretty much just an interesting (and demanding) job, with the understanding that if you do come out with some successful interesting research results they might also give you a degree at some point (which you would not get from most jobs, of course).
If I am remembering correctly then you have a lot of time to figure this out. Talking to professors and getting some experience in both research and animal care situations is likely to help you make the decision.
