To make a long story short, (IMO) I think it is best, to just find a vet that you trust and go by his recommendations. Of course, you should be cautious, ask for explanations.
Use the least amount of poisons/pesticides and vaccinations to keep your pet safe and comply with the law.
I have used prescription diet foods for my pets in the past and noted no adverse effects. Those foods, however, tend to be bland and boring, so you could ask your vet if it would be okay to add a bit of something to make it more tasty, even a spoonful of plain homemade chicken broth can make a big difference 🙂
