Speaking as someone who pretty much always lived in the suburbs, even in otherwise rural areas, and as someone who wouldn't mind doing mixed animal practice (especially small ruminants and camelids, but cattle are okay too), it's much more daunting to go from wanting to do small animal to food animal than vice versa. Much of food animal medicine is husbandry and that's pretty difficult to get a good handle on unless you've owned and worked with those sorts of animals extensively. It's not a huge deal to own a dog or cat and most people have. But only a much smaller number of people this day and age have even touched a cow, let alone worked them. If you have a non-animal science major and go into your interview saying you want to work with dogs and cats, no one would bat an eye. But not having little to no animal science experience and/or no real world experience is not easy at all to switch over. I'm just starting to get a little, but it's much more difficult to get into without previous experience if you formerly only wanted to do small animal stuff.
