3 steps to a healthy puppy.
1. Ask that the breeder not vaccinate your pup, even if the others in the litter will be vaccinated before they are sold.
2. Ask that your pup not be weaned before 8 weeks if possible.
While this was the norm for many years, in the last several years it has become fashionable to wean earlier, often at 6 weeks of age. In the wild, wolf pups would nurse longer, 8-10 weeks commonly.
Mom’s milk has both superior nutrition and immune goodies for your pup. Try to take advantage of that as long as you can.
3. When you take possession of your new pup, transition to a raw food diet if you can.
