Another theory states that the puppy that is conceived last will be the dwarf. This is an equally unfounded statement, considering that the mother dog's eggs are fertilized at the same time or in close proximity to him. All puppies in a litter are ultimately the same age. Yes, it's perfectly fine to pick up the little ones from the litter, provided they are healthy and receive the necessary care after birth.
Dwarfs, on the other hand, are often the last to be eaten, leading to inadequate nutrition and growth. Does this mean that dwarf dogs can't grow up to be happy, healthy, normal dogs? Not really. The smallest of the litter can be born in any order, so the last puppy to be born is not an indication of a weaker puppy. The dwarf will normally be determined by the amount of nutrients he received in the womb, not by his birth order.
Fortunately, an aggressive personality at puppy age doesn't necessarily translate into an aggressive adult, as long as dwarves are trained in early socialization, eat well, and show the same affection and care as their brothers and sisters. Most of the time, dwarves are the last to be born because they are also conceived later than other members of the litter. This makes them weaker and smaller, and some have underdeveloped skeletons and body organs. Dwarves may not be the largest at birth, but they can grow to become the largest in the litter as time goes on.
It has been said that dwarves are usually the smallest members of a litter and that dwarf development begins in utero. Not all dwarf puppies will make it, but those who do will have a special story for the rest of their lives. If the dwarf puppy has no underlying health problems, they are more than likely to grow to normal breed size once they start eating solid puppy food. So to answer the question, no, dwarves aren't likely to be more aggressive than the other puppies in the litter.
Make sure that the room your puppies are staying in is kept warm (86-89°F) and that older siblings don't keep the dwarf puppy away from their mother. Although it's heartbreaking to think about it, keep in mind that it's normal for some puppies in each litter not to survive. Just because the smallest of the litter starts small, this does not indicate that they will stay smaller than their littermates. Unlike “Pick of the Litter”, the healthiest and most powerful puppy, the smallest puppy.
If your current dwarf grows to a normal, healthy size, then it's absolutely possible that their litter is also normal size. Welcoming an adorable pet puppy into your home is always an exciting time, and as you choose from the litter, you're probably wondering which one is the “smallest” of the group. In canine terms, the smallest of the litter is the puppy that is considerably smaller than the other puppies at birth, and that may be slower to develop and ultimately reach a smaller adult size. A dwarf puppy may not have developed quickly enough because of a birth defect that prevented its growth.
The youngest members of the litter can enjoy the same quality of life as their stronger siblings, as long as they are cared for properly. Researching the personality traits of a dwarf dog is probably a good indication of what type of personality your dwarf dog will have.
