It is very interesting and fun to know about the growth of the puppies until their adulthood. The developmental stages of the puppies vary from their size. If it was a large breed, then the development is not much seen until two years. However, the English Toy Spaniel (also known as King Charles Spaniel) is a small breed, so its growth and developmental process are quick.

Therefore, the English Toy Spaniel puppy tends to physically mature at an early age, unlike other larger breeds.

The English Toy Spaniel can give birth to 4-6 puppies at a time. Dog remain pregnant for around 63 days (several days may vary) till they give birth to their puppies. The developmental stages of English Toy Spaniel puppies are explained below from birth to adulthood (until 1 year).

Stage 1: Newborn

The newly born puppies of the English Toy Spaniel is so small that it will fit perfectly on your palm. The puppy is completely deaf, blind, toothless and unable to walk for about two weeks of its birth. They are so helpless that they cannot even urinate or defecate by themselves. The mother will lick the abdomen of her puppies and it helps in stimulation that makes them urinate and defecate.

At this stage, they need warm, so they pile up against their mother body for warmth. If they are separated from the warmth, they might soon die of hypothermia.

Stage 2: Neonatal (0-2 weeks)

The neonatal stage starts from the puppies birth up to two weeks. They use their sense of smell and touch in the first week to get to their mother and siblings. They fully depend on their mother’s breast milk during the first few weeks of their birth.

Do not feed any solid food but only their mother’s milk as they are toothless and most importantly, breast milk contains colostrum. It is rich in antibodies that help protect the puppies from any kind of fatal diseases.

During his period, the puppies need a lot of sleep, which is about 90% in order to develop physically. You can see them growing in double size in the first week.

As the puppies are not able to support their body weight and cannot move, they crawl to get to their mother. These few movements in a day provide them with enough exercise for their muscles to develop.

Between 10 to 16 days, the puppies eyelids start to open and they begin to see blurry images which become clear in few weeks. The puppies learn their mother and siblings looks and try to communicate with them with their own vocabulary from grunts yelps, whines, and barks. They start to walk a little, stand and wag their tail and height and weight starts to increase rapidly.
