How to prepare for your first trip to the vet

Hello everyone! I recently acquired my first puppy, a mini Goldendoodle, and I am preparing for his initial veterinarian appointment. Frankly, I'm somewhat anxious because I desire everything to proceed as placidly and calmly as possible for him. I heard it is vital to have all paperwork prepared, know his inoculations, and select the proper moment for the consultation. I also learned that bringing his preferred toy or snack might help him feel more assured. Does anyone possess any suggestions or techniques to render a puppy's first vet trip more eased?
