When Do English Springer Spaniels Stop Growing?

English springer spaniels are one of the most beautiful and loving dogs, but also one of the most energetic, especially when they’re puppies! You would be forgiven for looking forward to your puppy growing out of its frantic phase. So, when do English springer spaniels stop growing?

English springer spaniels typically stop growing at 18-20 months, although it varies depending on the individual’s gender and genetics. They usually reach full physical maturity as medium-sized dogs at this age. Factors like malnutrition or worms may affect the growth of your spaniel.

Knowing when your English springer spaniel will stop growing allows you to give it the best environment to develop and prepare for its adulthood. Read on to learn more about the growth of these dogs: when they reach adulthood, how big they grow, and factors that stunt or delay their development.

When Do English Springer Spaniels Stop Growing?

Like all young dogs, English springer spaniels grow up fast! There is no hard-and-fast rule about how quickly an English springer spaniel reaches full physical maturity. The growth rate of these adorable and active puppies is impacted by many factors, including their diet, exercise, health, and genetic stock.

While it varies depending on the individual dog, English springer spaniels are typically considered to stop growing between 18 and 20 months. Each dog is different, and many springer spaniels continue to grow more for a few months after this; however, few of this breed reach maturity at a younger age.

Before the age of 18 to 20 months, English springer spaniel puppies have a lot of growing up to do! They go through many crucial developmental stages during this time as they transition from being puppies to fully grown adult dogs.

Springer puppies grow rapidly both physically and mentally during this time. They shift from utter dependence on their mothers for food, shelter, and reassurance to being weaned onto adult food, developing independence from their mothers, and learning how to listen to and interact with humans.

After 18 to 20 months, English springer spaniels are considered to have reached adulthood, and the hyperenergetic behaviors of their puppyhood generally come to an end (which may be quite a relief to their tired-out owners!).

How Big Do English Springer Spaniels Grow To Be?

So, how big will your English springer spaniel get when it reaches full maturity? Once again, this depends somewhat on the individual dog and its family genetics (such as the size of its parents and grandparents), as well as other factors.

 Just as some humans grow to be taller or heavier, some springer spaniel puppies will grow into bigger dogs than others of the same breed. However, there are typical weights and heights that you can expect your springer spaniel to reach.

Male English springer spaniels can be expected to reach a height of between 19 and 22 inches (48 and 56 cm) and to weigh between 44 and 55 pounds (20 and 25 kg).

The females of the breed typically grow to a height of about 18 to 20 inches (46 to 51 cm) and are typically at a healthy weight between 40 and 51 pounds (18 and 23 kg).

It is thus evident that the size of your English springer spaniel varies depending on the gender of your dog and that male spaniels typically grow to be larger and heavier than their female counterparts.

English springer spaniels are thus medium-sized dogs, although they are more robust than many other dogs of this size, as they have exceptionally sturdy bones and large paws. These features were selected for in the breeding of springer spaniels, as they aid the dogs in their role as hunting companions.

What Affects The Growth Of An English Springer Spaniel?

Several factors in the upbringing of an English springer spaniel may negatively impact its development. You wonder what these are and how best to care for these beautiful dogs to prevent their growth from being stunted or delayed.

Malnutrition Can Stunt An English Springer Spaniel’s Growth

The most common cause of impaired growth in English springer spaniels is malnutrition. Poor nutrition is not just caused by underfeeding but also by poor quality food or a poorly balanced diet. Malnutrition can mean that your spaniel may never reach their expected full height or weight.

To ensure this doesn’t happen, make sure that your dog is fed food that provides them with the proper nutrition (like sufficient protein, fats, calcium, and other vital vitamins and minerals). Proper nutrition is crucial for a puppy’s development, especially its muscles, joints, and bones.

Environmental Factors Impact English Springer Spaniels’ Growth

Environmental factors also play a significant role in the maturation of your English springer spaniel. Factors around your home that may affect your dog’s growth include its exposure to sunlight.

This is because a lack of light can negatively impact a puppy’s development. A lack of light is a particular concern during winter, especially in the north, where there are limited hours of light during the day, and there may be no direct sunlight for weeks at a time.

Try to ensure that your English springer spaniel is exposed to as much sunlight as possible, especially when it is a puppy.

The Health Of Your English Springer Spaniel Can Impact Its Growth

Another crucial factor in your spaniel’s growth is obviously its overall health. The effects of overall health on your spaniel’s development as a puppy are particularly evident through its exposure to exercise and illness.

Worms are particularly bad for your puppy’s growth, as they rob your dog of the vital nutrients it needs to grow. We recommend developing a worming routine with your veterinarian to ensure your English springer spaniel never catches them.

Keeping your puppy worm-free will prevent them from becoming sick and will ensure that they remain happy, fit, and healthy, and continues to grow, develop, and put on weight as they should. This allows

to grow into the best possible versions of themselves.

Exercise, on the other hand, has an immensely positive impact on your English springer spaniel’s growth. These active dogs require at least 40 minutes of exercise daily as adults and even more as puppies.

Regular exercise allows them to build, develop, and strengthen their muscles, bones, and joints and thus grow into healthy, fit, and strong adult dogs.


English springer spaniels are outstanding, energetic, and loyal dogs. They typically reach physical maturity between 18 and 20 months of age, although this varies. When they reach adulthood, English springer spaniels are typically 18 to 22 inches tall and weigh between 40 and 55 pounds. The growth and speed of growth of an English springer spaniel may, however, be affected by factors such as their diet, exercise, and health. To ensure that your beloved pet is developing at the rate that it should, make sure that it gets a properly nutritious diet, enough exercise, and is regularly dewormed.
