The development of the Puppy’s age stages

 Puppies are considered dogs from the moment they are born until they reach the age of one year. Every newborn puppy goes through many stages of growth throughout the first twelve weeks of its life. Each puppy, on the other hand, develops in its own manner, with smaller dogs developing faster and larger breeds not reaching physical maturity until they are two years old.

The rate of development varies by breed, and as previously said, proper puppy nutrition plays an important role. Puppies need a higher amount of protein, as well as a high concentration of good fats, such as omega-3 fatty acids, to help in their development. All pups are born reliant on their mothers, regardless of breed, and the adequate nutrients supplied by mamma throughout pregnancy assists in the growth of the puppy during its early stages.


Puppies are born blind, deaf, and toothless, and they are unable to regulate their body temperature, urinate, or defecate on their own. Their mother and littermates supply heat, and the pups huddle together in tight mounds to maintain a constant body temperature. When a puppy is taken from its warm, cozy home, he or she may suffer from hypothermia, or a drop in body temperature. To bring Mom's attention to their condition, cold, lonely puppies howl loudly.

When pups are cleansed by their mother's stroking tongue, they feel for the first time that they are being touched. Mom licks her babies all over to keep them and the nest clean, as well as to stimulate them to defecate and pee more often than normal.


From the time they are born, puppies can use their senses of smell and touch, allowing them to burrow around the nest in search of their mother's scent-marked breasts. When a woman gives birth to a child, the first milk she produces, known as colostrum, is rich in antibodies that provide passive immunity and help protect the kid against sickness in the early weeks of life. If you're breeding puppies, Fish4Dogs Salmon Oil is a great supplement to add to mom's regular food to supplement her diet with a high concentration of Omega 3 fatty acids that will be passed down to the pups.

During their first two weeks of life, puppies spend over 90% of their time resting, with the rest of their time spent awake nursing. Their whole focus is on growing, and in the first week, their birth weight more than doubles. Because neonates' front legs are incapable of sustaining their weight, they move about by paddling their front legs. The puppies receive the exercise they need to build their muscles and improve their coordination, and before long, they're crawling over and around each other and their mother.


During his second week of life, the puppy goes through a lot of changes. During this period, ears and eyelids that have been closed since birth begin to open, with ears opening about two weeks after birth and eyelids opening between ten and sixteen days after birth. The fuzzy babies have a unique perspective on their environment as a result of this. You can see and hear how they learn about their mother and other dogs, as well as how they develop their own language, which ranges from grunts and mews to yelps and whines. By the 15th day, puppies are normally able to stand and take their first shaky steps.

By the time a puppy reaches three weeks of age, it has progressed from the neonatal stage to the transitional phase. This is a stage of rapid physical and sensory development during which the pups transition from total reliance on their mother to a degree of independence. They start interacting with their litter mates, learning about their environment and canine society, and sampling food from their mother's reward dish. Puppy teeth appear between the ages of five and six weeks and continue to erupt until all of the baby teeth have erupted. By this age, puppies are able to control their need to pee and begin to walk out from their sleeping quarters to relieve themselves.


Puppies often go through a period of "fear" at this time. When they come across new or familiar people or objects, they react with anxiety rather than curiosity. Anything that terrifies them at this age might have a long-term impact, so don't overstimulate the baby by presenting too many changes or obstacles at once. This does not mean that your puppy will grow up to be a scaredy-cat; rather, it is a normal period of development during which pups learn to be more cautious. It's crucial to mingle cautiously at this period to prevent fearful reactions.

Puppies may be placed in new homes with their family after they have successfully learnt to feed on their own. Although they will be better adjusted and make better companions if they are allowed to stay in the same environment and interact with their littermates and mother dog until they are at least eight weeks old (the older the better), it is through interaction with siblings and Mom that they learn bite restraint, how to recognize and respond appropriately to typical canine communication, and their place in canine society. Puppies at this age also make more smooth transitions from one location to the next than they would otherwise.

Your puppy still has a long way to go before he reaches adulthood. He will not be considered an adult until he has gone through several more developmental stages and has reached the age of one to two years.

Despite the fact that he seems to be an adult, pups go through a number of growth stages that last from birth to a year or even two before they are considered completely mature. Between the ages of six and twelve weeks, the most important changes in a puppy's growth occur. Your pet, on the other hand, will have a lot of developing to do after twelve weeks.


Puppies at this age have boundless curiosity, irritable stubbornness, and a strong devotion to their family. You will not be disappointed if you expect your puppy to get into everything. Now is an excellent time to begin training your puppy to be obedient.

The juvenile puppy period usually begins at the age of ten weeks and lasts until the puppy reaches puberty and begins to develop sexual maturity. Puppies begin to grasp the consequences of their actions at this age and to choose which behaviors are most appropriate in certain contexts.

The majority of the day is spent in play, which is not only enjoyable for the babies but also good training for life as a dog. When puppies are young, they are taught how to conduct important canine activities including chasing and running, pawing, biting, and fighting.

The development of social skills and canine etiquette requires interaction with littermates and Mom. When pups bite one other, they learn to control their bite and communicate with each other via canine language. They develop dominating and submissive postures via play, which helps them prepare for adulthood.


Puppies push their limitations during this period, which may span anywhere from a few days to many weeks, to test how far they can go. These canines argue with their owners to see who has the last word, seem to "forget" whatever training they've received, and act like disturbed teenagers.

The teething phase is at blame for some of this. At the age of three months, puppies begin to lose their baby teeth. Puppies may endure difficulty when their permanent teeth begin to emerge, prompting them to chew on anything and everything to relieve the pain.

Other variables, in addition to hormones, may influence delinquent behavior. Unlike many other animals, a male puppy's testosterone level between the ages of four and ten months may be up to five times higher than that of an adult dog. That way, the older dogs are aware that he is a puppy and so need "schooling" in dog etiquette; they make sure to take him down a peg and teach him manners before he becomes too big for his furry britches.

Even pups who have already been spayed or neutered may get the "oh yeah, MAKE ME!" mindset following this. Even individuals who have followed all of the instructions to the letter may find themselves in this difficult and unpleasant situation. As you continue to teach, clench your teeth, keep him on a leash and under control, offer frequent, gentle, and loving instruction, and tell yourself, "He's testing me, it'll get better." Because it is certain to happen.


Puppies grow so quickly at this age that you may see changes on a daily basis. Not only will your puppy put you to the test, but this is also the time when puppies figure out where they fit in with the rest of the pack. It is expected that some squabbling and play fighting may occur. For dogs, the rule is that older animals teach their puppies limits, which is normal but often seems more terrifying than it is.

In truth, an unneutered male puppy's testosterone level begins to rise at about 4 to 5 months of age if the dog has not been neutered. Adult dogs recognize that even giant puppies are still newborns and must be taught excellent canine manners as they get older in this way.

Puppy feel safe

Puppies may go through another fear phase around this time, which is typical. It may last up to a month, and in some situations, it can even linger longer, especially in large breed dogs. This is totally normal and should not be seen as a reason for alarm. You may observe some "flaky" behavior or unwarranted aggression, as well as a propensity to become unduly protective of toys or territorial borders, which frequently corresponds with developmental spurts.

 Make sure you know how to communicate with puppies and avoid using baby language to avoid encouraging nervous behavior with more attention. Rather than risk reinforcing the anxiety with a reward, it is best to ignore it. Build the dog's confidence via training, and he should be able to transition out of it without any problems.


While the baby may still be emotionally immature at this period, male pups begin to elevate their legs and urinate to establish their territory. By 10 months, testosterone levels in male puppies are 5-7 times higher than those in adult dogs, and then gradually fall to levels observed in adult dogs by 18 months, when they are considered completely developed.

At this period, there may be more adult-pup fights because it serves as a signal to the older male canines that the juvenile must be put in his place. Female puppies may go into heat (estrus) as early as five to six months old, and male puppies may show an interest in sex at the same time. Although the bulk of your puppy's height growth will be complete by this time, he may continue to fill out and gain muscle mass as well as body weight. At this stage, the puppy coat starts to give way to the adult coat.

Puppies at this age seem to have endless energy, and they will flourish if they are given supervised play and exercise.

The socialization and training of a juvenile should be continuous to ensure that he or she knows how to behave correctly among other dogs, other animals such as cats, and other people, including children and strangers of all sizes, ages, and looks.


This is the age at which your dog becomes physically mature, which varies by breed. Tiny dogs grow much faster than huge dogs, and larger dogs mature much more slowly than small dogs. Your child's social development may be influenced by the amount of time he or she has spent with other animals. Socialization and training will continue as long as your pet lives since there will always be new things to learn or old ones to study and practice. After all, the joy you have in the first year or two with your puppy foreshadows a lifetime of love to come.

If you have a puppy, after a particular length of time, you should cease giving it puppy food.

Puppies and adult dogs need particular nutrition, which is an important part of their care. The majority of dog owners are aware that puppies need special food to aid in their growth and development. On the other hand, many dog owners are unclear whether it is time to switch their pups to adult dog food. This is because there is no one-size-fits-all rule that applies to all canines. Different dog breeds mature at different rates. You and your veterinarian may collaborate to identify the best time to make the meal change for your puppy.

Administration for Puppy Food

Puppies need more calories than adult dogs to sustain their growth, development, and high levels of energy. Young pups need nearly double the amount of calories as adult dogs of the same size.

As your puppy approaches maturity, his development slows and his nutritional needs decrease. Continuing to give your dog puppy food after his development has slowed can result in weight gain. Increased weight may quickly turn into obesity, which can lead to a slew of health issues.

When Is It Appropriate to Begin Eating Adult Foods?

Dogs are considered puppies until they reach the age of around a year. Breeds, on the other hand, reach different stages of maturity at different times. Consider that many large and enormous breed dogs are still considered puppies until they are two or more years old, and they will need to be given puppy food until they are one or two years old.

A few little dog breeds, on the other hand, reach adulthood before they reach the age of one year! Your veterinarian is the most credible source of advice when it comes to your dog's nutrition, so talk to him or her before converting to adult food.

When deciding on the optimal time to offer adult dog food, it's advisable to do so around the time the puppy's development ceases but before he starts to acquire excessive weight. Keep an eye on your puppy's weight and height to discover if they're growing at a slower rate than predicted.

The majority of dogs reach a growth plateau around the age of one year, however in certain circumstances, you may notice a decrease in growth as early as eight or nine months of age.
