Puppy Milestones and Stages:

The first stage in a puppy’s development is birth, which happens when a mommy dog gives birth to her litter of pups. The birth process can take anywhere from two to 24 hours, with most mama dogs giving birth in just a few short hours. During this time, the momma dog will lick her puppies clean and spend plenty of time grooming and tending to their needs until they’re ready to find their first feeding!

First week:

This is the first week in your puppy’s life, and it can be a very important time – both for you and your little one. During this period, puppies will start opening their eyes to the world around them. He will not be able to see very well at first, but over his first week, that sight will develop and sharpen.

During the first week of life, your puppy will spend most of its time sleeping, nursing, and learning to regulate its temperature. They might also encounter a bit of gastrointestinal upset – which means that they’ll need plenty of momma dog’s milk to keep puppy healthy and help get rid of any extra gas or discomfort they’re feeling.

The temperature of the environment will also affect the amount of energy a puppy has, so you’ll want to keep your little guy close to ts momma (or a heat source) during this time to make sure he’s comfortable and warm.

The weight of a puppy can also change dramatically during the first week of life. A puppy that weighs three ounces at birth may increase their gain weight by as much as 100% within just one week, so keep track of your puppy weight chart and how they are growing to other puppies in the litter.

Second Week:

During their second week, your puppy will be learning to feed. As they start to open their eyes and learn the world around them, a puppy’s curiosity can border on the uncomfortable – both for them and for you! Your puppy’s legs will become more stable, and he’ll start to stand up on his own. But your puppy can still stand up and walk yet, so be sure to keep any hazards like electrical cords or small toys out of your puppy’s reach during this time.

Your puppy will also start to regulate his temperature slightly better and have more energy, which means that he’ll need to go outside more often – especially if you live in a climate where the temperatures are warm. Be sure to keep an eye on your puppy’s temperature and ability to regulate it, as he can develop heat stroke or hypothermia if temperatures are too warm or too cold during this growth stage.

The weight of your puppy will continue to change during this time, and he may even start to act differently from his siblings – which can be a sign that your little guy is the runt of his litter. If you notice any personality or growth differences among your puppies, speak with your breeder about why they think that particular puppy might be a runt.

Third Week:

During this week, your puppy will become even more mobile, which means he’ll start exploring the world around him. As he becomes more curious about his environment and starts to learn about the world outside of his momma’s warm belly, your puppy will also start to initiate standing up. But he might not be able to support his body weight yet, so you’ll want to make sure that your furniture is puppy-proofed during this week.

The puppy’s weight will definitely change during this week, and he may even start to lose some weight – which can be a sign that he’s not getting enough milk from his momma and might need to be supplemented with formula. So be sure to watch your puppy carefully for any behavioral or physical changes that might signal that he’s not thriving or growing as quickly as you would expect.

Your puppy will also start to develop his sense of sight and hearing so that he might be frightened or startled by loud noises during this time. You must be alert to your mixed breed dog outside the house, as new sounds and smells can startle him.

Fourth Week:

This is the age of exploration for your puppy! He’ll start to walk, run and play with his siblings. But these are all new activities for him, so he might get into trouble if you’re not careful where he’s allowed in the house. Even if you’ve puppy-proofed your home before bringing him home, your pup may try to get into things he wasn’t able to before. Keep an eye on your new puppy in this stage of development and make sure that all potential hazards are out of his reach.

During this week, your puppy will start to eat solid food for the first time. As he transitions from milk to more digestible food items, your puppy will develop his digestive system and may even start to test out different foods – which means that you should watch him carefully for any signs of an upset stomach or diarrhea. A feeding schedule can be critical for a puppy’s development.

Start by introducing your pup to smaller pieces of food like baby rice cereal, and then work up to firmer foods like kibble as he grows older. Your puppy will also start to grow more teeth during this week, which can make it harder for them to eat the kibble unless you soften it with a warm bath or you combine the kibble with other food items like wet puppy food.

Fifth Week:

Your puppy is now becoming a real dog, and he’ll start to explore his home in greater detail. But your little guy still doesn’t know to go potty inside the house or chew up your favorite pair of shoes, so you must be careful to watch him closely during this week. New environments and different people can startle your puppy, so introduce him to new places and people slowly and patiently.

When you’re introducing your puppy to new environments or unfamiliar people, check in on him often to make sure that he’s not frightened by his surroundings. He may even try to let out a small bark as an instinctual way to defend himself from unfamiliar people or situations.

Don’t be surprised if your puppy starts to spend more time sleeping during this age – he needs a lot of rest to grow into the adult dog he’ll become. You can help him by keeping an eye on potential hazards like power cords, which can look very similar to chew toys to a young puppy.

Sixth Week:

This is when your puppy will become aware of his surroundings and make some of his first decisions. He might choose not to go potty inside or walk into new environments on his own. While he’ll still need lots of support, this week can be an exciting time as your puppy starts to become aware of his environment and make choices on his own.

It’s also a time when you should start to take control – but don’t force your puppy into new situations or discipline him for something he might not understand. Your pup will start making some silly mistakes during this week, but it’s up to you to be patient with him and make sure that he doesn’t get hurt.

Seventh Week:

Just like a toddler, your puppy will start to become more mobile and adventurous during this week of his development. He’ll start to climb up furniture, jump from place to place, and run around wildly. But because he’s new at these types of behavior, he’ll need your guidance to teach him how to do these things safely.

Don’t be surprised if your puppy starts chewing on his own toys or tries to chew up things around the house that aren’t supposed to be chewed. This is a sign that he’s exploring and testing out what objects are appropriate for his teeth and what objects are not.

Remember to provide plenty of chew toys for your puppy to use as he grows older, especially if you want him to learn how to be gentle when chewing on household items. And make sure all sharp edges are padded or covered so that they don’t hurt your pup while he’s learning how to be a proper dog.

Eighth Week:

Your puppy is now at the peak of his development, so make sure you’re ready to guide him into adulthood during this week. This means taking control of your puppy’s environment and ensuring he lives in a safe place that encourages good behavior.

You’ll also need to start training your puppy – but only if he’s starting to show signs of interest in learning commands and obeying his master. If your puppy is uninterested in learning, it’s best to wait until another week to start training him.

Remember that this is an exciting time for you and your puppy, but he’ll also be going through some big changes with his hormones. This means he may run away from home more often or become more vocal than usual.

3-Month-Old Puppy:

Your most important goal at this age is to train and socialize your puppy. If you’ve been waiting until now to do these things, make sure you’re patient with your dog to get the best results from him. The first vaccination is also administered, and your puppy should be protected from parvovirus, distemper, adenovirus-2, and hepatitis.

You should also avoid treating your dog too harshly, as punishments can often cause him to feel fearful or angry. In this situation, your puppy will start to learn that he needs an aggressive response to be safe – and this could hurt his personality down the line. Potty training will also become more important as your puppy is now getting old enough to understand what it means.

Six-Month-Old Puppy:

Small and toy breeds like Toy Poodle or Shih Tzu shouldn’t be expected to have finished their development until the age of 12 months. Large and giant breeds like Bernese Mountain dog, on the other hand, is usually considered a full-grown dog after just six months old.

During this time, your puppy’s growth will have slowed down, and he’ll start to develop a more adult-like appearance. He’ll also be able to focus on training better and understand that commands should always be followed. During these months of development, the major nutrients needed by your dog are protein and fat.

A large-breed puppy development will take much longer than a small-breed puppy, which is why experts recommend that you avoid making him gain too much adult weight. Make sure to work closely with your vet and stick to an approved diet chart within the first six months of your dog’s life.

Female dogs will also enter their first heat cycle, which is an important time to get your dog spayed. Although it’s not required during the first heat cycle, this procedure should be done before any possible pregnancy occurs.

The fact that your puppy is growing up doesn’t mean that you can stop training him. Your dog will still need constant attention to ensure he knows the difference between good and bad behavior. This means continuing to give positive reinforcement for good behavior and negative reinforcement for bad behavior at all times, even when you’re playing with him.

1 Year Old:

Your puppy is now like adult dog capable of learning many different commands and a great understanding of right and wrong. Your focus should now be taken off training and given to ensuring that your dog knows what it means to be a family pet. This can include taking trips away from home or introducing him to other people and animals.

While the first year is just as important, you need to start thinking about preparing your dog for his older years by being more careful with what you feed him. By now, he should be of any growth food recommended during his development. It’s time to get your puppy neutered and switch him to a regular adult diet that keeps him looking his best.


You should now have a better idea of the growth and development changes that will occur with your puppy as he ages. The best thing you can do for him is to provide plenty of attention and make sure that he stays at a healthy weight each day. Take this chance to bond with him as an early foundation for his life ahead, and you’ll be rewarded with many years of happiness. Remember to socialize your puppy with other people and dogs so that he can get used to others as he grows up.
