Are you the proud new paw parent of a Corgi puppy? This is a wonderful time full of fun but also plenty of questions. One of the biggest questions new owners have is, “how big will my Corgi get?

Corgis are an adorable, incredibly agreeable breed and make fantastic pets. They are small to medium-sized dogs that only reach about 30 pounds when fully grown. Along with wondering how big they will be as adults, new pet parents want to know what to expect as their pup moves through different growth guidelines. Having a reference point and knowing what to expect can be helpful.

Corgis are among the most popular dog breeds, and for a good reason. Their small size, spunky personalities, and loyalty make them great members of any family. Always remember that your pup is still a growing animal and will have different needs throughout its development. Of course, all dogs and unique animals will grow to the perfect size for them. They can be bigger or larger than their parents or siblings. Let’s discuss overall growth guidelines, puppy milestones, and various factors that impact a pup’s growth.

Corgi Breed

The Cardigan Welsh Corgi is an older breed than the Pembroke Welsh.

Corgis are classified as a medium-sized breed, with males and females typically weighing between 25-30 pounds. Corgis are a ” double-coated breed,” meaning they have an outer layer of fur that is longer and thicker than the inner layer. This coat helps to protect them from cold temperatures and helps to keep them insulated. Males and females are very similar in size in this breed.

The Corgi breed is known for having a longer lifespan than other breeds and typically lives 12-13 years. As with any dog, there are a variety of factors that can contribute to overall health and life span. Proper nutrition, exercise, and healthcare are all critical factors in ensuring your Corgi enjoys a full and healthy life.

Corgis are known for being incredibly smart as well as very agreeable. They enjoy being around their human companions and can get bored and destructive when left home alone. There are two different kinds of Corgis: Pembroke Welsh and Cardigan Welsh. Cardigans are slightly larger than Pembrokes and can reach about 38 pounds when fully grown. Both breeds look similar, with short round legs, stout bodies, and pointed foxy ears and snouts. And who can forget that adorable little tail and wiggle butt?

What To Expect

We know that Corgis are adorable dogs reaching about 30 pounds when fully grown. There is more to a dog’s growth than just how much they weigh or how tall they stand. It is wise to look at the specific developmental milestones they experience over their first year. Growth charts are useful tools to help owners track their fur baby’s progress. Keep in mind that these are not exact predictions of how large any specific dog will be. They are a reference point for informational purposes only.

Reminders

Remember that all dogs are different and will grow on their own unique timeline. All puppies will experience growth spurts and plateaus throughout their first year and beyond. These are unpredictable but are perfectly normal.

Adult Corgis will reach their full size around one year old but may continue filling out until they reach two or three years old. However, it is a good rule of thumb that this breed reaches full weight and height at around one year old. This is also when they are considered adult dogs.

A dog’s growth is influenced significantly by nutrition and lifestyle. It is very important to feed them top-quality nutrition from day one and not over or underfeed them. If you are concerned about your Corgi’s growth, whether it seems too slow or too fast, it is best to seek advice from your veterinarian. They can evaluate your dog’s development and rule out any underlying health concerns.

Puppy Growth Timeline

Corgi puppies go through many different phases of growth and development.

This information will help you provide the best care possible for your dog as they go through this period of rapid growth. A Corgi reaches about half of their adult weight around the time they reach 5 or 6 months old. Knowing the growth milestones for each month of your puppy’s first year can help you understand your pup’s development and provide the best care.

At eight weeks old, Corgis are typically about 8-10 inches tall and weigh around 10-15 pounds. At four months old, they may be around 10-12 inches tall and weigh around 15-20 pounds. At six months old, they may be around 11-13 inches tall and weigh around 18-25 pounds. As your Corgi grows, their weight and height will continue to increase.

Birth To 2 Weeks

Newborn Corgis weigh very little, around 1 to 2 pounds. During this time, puppies do not do much but nurse from their mothers and sleep. They are born completely blind and deaf. They will need to stick close to their mom. When they reach about two weeks old, their eyes and ears will begin to open.

1 Month

During your puppy’s first month, they will start to open their eyes and ears and become more aware of their surroundings. They will start to explore their environment and will be very curious. Your puppy will start to recognize different sounds and learn to respond to their name. They will also start to recognize family members and become more sociable. Your puppy’s physical development will be slow in the first month. Their legs will be wobbly, and they cannot stand independently yet. They will start to crawl but will not have the coordination to walk. You can offer your pup puppy mush, puppy kibble soaked in water. They will still want to be near mom and try to nurse but will wean soon. A one-month-old Corgi will weigh between 4 and 7 pounds.

2 Months

During the second month, your puppy will get better at standing independently and walking. They will be more coordinated and will explore their environment more. They will also learn to bark and growl, so be sure to teach them proper behaviors at this stage. Your puppy’s teeth start to come in during the second month, and they will play more. They will become more curious and will want to explore more. You may see some teething behaviors like mouthing and chewing. Your Corgi pup will weigh between 7 and 10 pounds.

3 Months

During the third month, your puppy will become even more active and will start to explore further away from home. They become more social and will begin to learn more commands. You can start leash training, and your puppy should be fully on high-quality puppy chow.

Your puppy’s physical growth will increase this month, and they will be able to run and jump more. At three months of age, your Corgi should be almost double their birth weight and show signs of independence. They should also begin recognizing basic commands and be more comfortable around other dogs and people. Socialization, training, and house training are in progress. If you need some assistance with training, try looking into puppy courses. Your pup is energetic, curious, and newly confident. Your Corgi pup will weigh between 10 and 13 pounds.

4 Months

By four months old, your puppy is very playful. They will feel very comfortable at home and continue learning new things daily. Focus on socialization and obedience training right now, especially if you have young children or other pets. Your puppy will be a handful right now, high in energy and easily stimulated. By now, they should have already been to the vet for the first set of puppy vaccinations. Housebreaking should be fairly well in place, and you should start having conversations about when to spay and neuter if you have not already. The average weight right now is about 13 to 16 pounds.

5 Months

At five months old, your Corgi will likely be about half of their adult weight. They are still incredibly playful but are growing rapidly and may be a bit clumsy. Their adult teeth will begin growing in, but they should continue on puppy chow until they reach about a year old. Your dog should be well established in a daily routine, with specific mealtimes. It is very important not to freely feed this breed as they tend to overeat. Puppies will weigh around 16 to 20 pounds.

6 Months

Weight gain will slow down now, and your six-month-old puppy may start to calm down a little. They are still growing rapidly and have a ton of energy, so they need regular exercise and proper nutrition. This breed is known for being mischievous, so they should be very well supervised. This is a good breed to crate train if you need to leave for extended periods of time. Corgis tend to get into a lot of trouble when left unsupervised and can be very destructive despite their smaller size. Expect your pooch to weigh around 20 to 23 pounds.

7 Months

Around now, your dog may start to look like an adult Corgi. They are very agreeable, fluffy, and ready to please. Keep in mind that your dog is likely going to try and test limits regularly. You must continue to reinforce training, as well as introduce new skills. Regular daily walks provide socialization. It’s very important not to overexert your pup, even though they have a lot of energy and love to play. Overexertion and extra stress on their joints and bones can lead to painful conditions like hip dysplasia. Both males and females will weigh 20 to 25 pounds about now.

8 Months

At eight months old, your Corgi is an old pro. By now, the two of you should have a well-established routine. Remember that this breed can be prone to separation anxiety and may start acting out. Make time every day for regular walks and one-on-one play times. Remember that the Corgi is a breed considered a Velcro dog. They like to be around people and, regardless of age, can get into trouble when left alone.

There will still be minimal weight gain, but your dog will be very close to full adult size. Weight is around 22 to 27 pounds.

9 Months

Can you believe your Corgi only weighed about four pounds just nine months ago? Right now, your dog is growing steadily and continuing to learn more every day. Appropriate behavior, mealtimes, and house training should all be old hat by now. This is a good time to start researching adult kibble and wet and fresh food options. Within the next two months, you will start the transition to adult food. Your pup will weigh around 28 pounds at this age.

10 Months

Corgis can weigh anywhere from 25 to 28 or so pounds at ten months of age. You will start to see significant behavioral changes and may see a slight decrease in energy. Try to stick to your dog’s regular routine and be consistent. Make sure there is plenty of time for exercise and that they continue to get one-on-one attention from you. Your dog may go through some growing pains and try to test limits. However, firm redirection of training is helpful. Make sure to provide plenty of mental and physical stimulation. Start to prepare yourself to begin the transition to adult food next month.

11 Months

At eleven months, a Corgi will weigh between 28 and 30 pounds. You will not see much more apparent growth, though your pup can still have an occasional growth spurt. Make sure your pup gets at least 2 exercise sessions daily, including a walk around the block or a fun game of fetch in the backyard. Your dog should eat two to three times a day. You can start by adding a small amount of adult food with their puppy chow. Gradually phase out the puppy chow over the next couple of months.

Factors To Consider

A few different factors impact a dog’s physical development and growth. Some of these variables owners can control, like nutrition and lifestyle, while others, like genetics and health, are sometimes up to chance. Familiarizing yourself with the factors that will impact your dog’s health, growth, and development is important. Remember that your veterinarian is your teammate in keeping your dog happy and healthy, so never be afraid to ask questions or schedule a consultation if you have concerns.

Genetics

Genetics is a huge factor in how large a dog will get. One indicator is to look at parent sizes, but there is always room for unpredictability. Parents can carry the genetics of other breeds, and there is no real way to tell how big a dog will get until they reach adulthood. A mixed breed tends to be larger than purebreds. You can get a canine DNA test to understand better exactly what breeds your pup has in them.

Nutrition

Nutrition is one of the key factors in a dog’s health and development. Nutrition plays a crucial factor in how big or small your dog gets. A dog eating more will not grow bigger. They only become overweight, which is unhealthy. Corgis love their food and are always looking for more. It is essential to control how much they eat and keep them on a regular feeding schedule to keep them from putting on excess weight and causing undue strain on their bodies.

Growth Spurts & Plateaus

All dogs, regardless of the breed, will experience growth spurts and plateaus as they develop. This is partly because of the substantial amounts of energy they use to grow. Keep in mind that lulls in growth and periods of rapid growth are normal but unexpected. They can happen anytime during a dog’s first few years of life.

Growth spurts and plateaus can be worrisome for owners and may cause concerns over their dog’s development. Make sure to bring up these concerns with your veterinarian. Even though it is normal for dogs to experience different growth phases, it is always a good idea to have them checked out if you have concerns. If you notice your dog putting on a lot of weight quickly, not gaining weight, or seeming to lag in development, it is best to check with your veterinarian.

Spay & Neuter

The spay and neuter process can impact a dog’s development. While it does not necessarily impact how large they grow, it can affect lifelong health. Doing this too early or too late is a concern. Because of this, it is essential to discuss with your veterinarian when your pup is young rather than waiting until they are older. Remember that males and females need to be fixed at different times. Female dogs who get spayed too young can develop incontinence issues later in life.

Choosing the right time to do this depends on your dog’s specific circumstances and health. Make sure to ask about this when your dog is about four months old to ensure that you do not wait too long.

Physical Health & Activity

A dog’s physical health and activity level go hand in hand. Dogs that are not healthy or are suffering from underlying medical conditions may not grow as quickly or as large. Dogs that receive poor nutrition will not be as healthy and may develop slower than others. Puppies that have too much exercise and overwork their bodies can develop exhaustion, anxiety, and mobility issues. Physical activity is very important, but it is essential to make sure to do the right amount for your dog. You do not want to overexert or injure them; conversely, you do not want to allow your pup to become a couch potato.

A dog’s physical health is another building block to their healthy growth and development. Providing them with the best possible food, medical care, and a safe and comfortable home will provide the best environment for healthy growth and development.

It is also important not to overlook dental health. It is pivotal to start cleaning your puppies’ teeth when they are young. Severe dental disease can develop by the time a dog is 2 years old, and if not treated, can take years off their life. Discuss dental cleanings with your veterinarian.

Care

A Corgi’s living environment and level of care will impact their overall growth and development. Dogs who are kept alone, in dark rooms, with no entertainment, will become withdrawn and may develop slowly. They can have a poor appetite, low energy, and poor physical health. Dogs must be kept safe and secure when their owners are not home. They should always feel safe and have a comfortable space to call their own.

Dogs do better when they have regular access to outdoor activities. This includes walks around the neighborhood, trips to the dog park, and several sessions of playing fetch outside. Corgis adore people and need to be around them most of the time. They are not a breed that does well independently, so owners need to consider this. How well a dog is cared for affects their overall health, growth, and development.
