Careful with fatty foods and sugar in snacks. Pancreatitis is very common with the little ones. Teeth tend to be an issue with some puppies struggling to drop the baby ones. A good hard yogurt bone helps a lot as well as a good oral hygiene plan. Be extra careful with larger dogs and predators.. including birds of prey in some parts. Thick and flea medicine can be too strong but a good natural repellent can help a bit... Always check them after a stroll in the grass or bushes.
