A dwarf puppy should gain no less than 5% and up to 10% of their current body weight every day for the first month. Do the dwarves in the litter grow to their normal size? Yes, dwarves can grow and will often grow to match the size of their siblings. While the dwarf may still be smaller than the other puppies even when they are fully developed, it is quite normal for them to catch up. Once they begin to receive proper care, dwarves will grow.
Dwarf puppies don't stay small. In fact, when the puppy is fully grown (between 6 and 18 months), you will have no idea it was the smallest. Within 6 to 8 weeks, the dwarves will begin to reach the weight of their siblings. The term “dwarf” is often used to designate puppies that are born smaller in size or with a lower birth weight.
However, dwarf puppies are not always small. On the other hand, puppies who take this term may differ only from their siblings by their strength, be weaker and not thrive. Not all litters contain a dwarf; in fact, many dog mothers give birth to a group of puppies of average size and weight and who are in excellent health. Another way to see a dwarf would be a puppy that has physical disadvantages that prevent it from receiving proper nutrition and care from the mother.
In the natural selection process, there is competition between newborn and nursing puppies for access to milk and access to warmer places near the dam. Puppies that have these physical advantages in strength and size from the start tend to grow faster. In a few days and weeks, the difference that began barely noticeable is magnified. A puppy that may not be noticeably smaller or sicker than its littermates at birth can obviously turn into a dwarf within a week.
The reason for this is that, for whatever reason, this puppy cannot compete with his brothers and sisters for milk and warmth. Litters compete for milk and prime locations near the dam, especially in crowded litters. Puppies that have this advantage from the start grow to be the strongest and grow faster than their litter mates. Dwarfs, on the other hand, are often the last to eat, resulting in inadequate nutrition and growth.
Does this mean that dwarf dogs can't grow up to be happy, healthy, full-size dogs? Not really. If your breeder has experience, they will know that the dwarf is worth as much as any of the other puppies. The puppies are in constant motion, exchanging positions with their siblings until the moment of birth. Keeping the puppy's room at a high temperature is one way to provide the heat control necessary for a small puppy to bloom.
However, if the mother leaves her puppies alone or rejects them, they should be provided with an external source of heat, especially the dwarf. Since dwarves are smaller or weaker than the rest of the puppy squad, they do experience several disadvantages, but one of the main disadvantages is that it is more difficult for the dwarf to compete for the milk that the mother dog provides to her litter. A Kansas State University study reported that puppies born with a weight that was 25% lower than the average newborn size for that breed would not survive. Researching the personality traits of your dwarf's dog breed is probably a good indicator of what type of personality your dwarf will have.
These conditions need to be addressed for the health not only of the dwarf but of the entire litter and, ultimately, of the prey itself. I would like to offer a warning about breeders of so-called teacup puppies or micro puppies trying to sell dwarfs for a premium, making them seem valuable and in demand. A lot of growth occurs in those first few weeks, and a lack of weight gain may indicate that the dwarf needs human intervention. However, for small puppies with health conditions that will affect them throughout their lives, a special price and contract should be arranged detailing the puppy's lifelong expectations of support and compensation before the family takes their puppy home.
One of the biggest problems a dwarf faces is the lack of strength to reach their mother's nipples and receive adequate nutrition through breastfeeding. Any infection or communicable disease from the mother will affect a smaller puppy or the dwarf with worse consequences than the most resistant pups in the litter. Weighing each puppy in the litter will help you identify the small birth-weight puppy (dwarf) in the litter. .
