This is a very common misconception, but the answer is no. They are, however, equivalent to newborn babies and require a lot more care and attention than your average sized puppy. Because of their tiny size and delicate nature, their immune systems can be compromised, so you need to be a little more careful in what they come into contact with and how they are handled. As they get older, their immune systems grow stronger and they are just as healthy as any other dog. All our puppies must pass a physical from our certified vet and also CIFA government vet before they are shipped to their new homes.
