At What Age Are Springer Spaniels Fully Grown?

Springer puppies seem to grow up so fast. One day, they are adorable little furry balls, and then, in what seems like the blink of an eye, they are fully grown into incredible canine companions.

The best way to determine how big a Springer Spaniel will get is to take a look at their parents. Generally, Springer Spaniels reach adulthood by 18 – 20 months. These are averages and may vary slightly. Keep in mind that, even after the bones are fully developed, your Springer puppy will continue to develop fat and muscle mass as it ages.

Factors Affecting Springer Spaniels’ Growth 

Here are some factors that affect the growth of Springer Spaniels:


Your Springer Spaniel’s genetics can determine whether it will be taller, shorter, or more prone to weight gain. Some genetic health conditions could affect your Springer Spaniel puppy’s growth.

If your Springer Spaniel is the “pick of the litter”, it will be more strong and big by nature. If your canine is the “runt of the litter”, it will be smaller by nature. If your puppy came from tiny parents, it is likely to be smaller than average, and vice versa for larger parents.

Diet has a huge effect on the weight of your Springer Spaniel. Good nutrition can determine how well your Springer Spaniel grows. Healthy and good nutrition supports normal growth and maintains the puppy at a healthy weight and better body condition. 


Parasites are a very common cause of weight loss or a lack of weight gain in Springer Spaniels. These parasites and intestinal worms can steal enough calories from the puppy to slow down its growth. Springer Spaniel puppies that have a heavy worm burden typically look small and unhealthy. If you suspect worms or parasites, take your puppy to the vet to be checked. Of course, “an ounce of prevention is worth a pound of cure” so, it is always best to stay up to date with shots and preventative treatments to prevent your puppy from getting sick in the first place.

Physical Activity

Another factor that will affect your Springer Spaniel’s weight is its physical activity. Springer Spaniels require a good amount of exercise to keep them healthy and prevent them from becoming overweight.  

Health and Ailment

Good health is important for growing puppies. Your Springer Spaniel might be short and underweight due to an illness. If it seems to be sick, the best option would be to take your dog to a vet.

How Do I Know if My Springer Spaniel is Underweight or Overweight?

All dogs are individuals; however, they should neither be too skinny, nor too fat. There are several ways to spot if your Springer Spaniel is overweight or underweight:

  • Apply a little pressure to your Springer Spaniel’s chest and you should be able to feel their ribcage. If you can barely feel the ribs at all, this is a fair indication that your Springer Spaniel is overweight.
  • When Springer Spaniels are out of shape and overweight, they get tired and will become fatigued and overexerted easily.
  • If you can see their prominent bones including ribs, spine, and pelvic bones then your Springer Spaniel needs to gain weight.
  • If you notice that there isn’t any fat or muscle on your Springer Spaniel, it is a severe symptom of being underweight.

How Can You Help Your Springer Spaniel Grow?

It is crucial to provide your Springer Spaniel with the proper diet and exercise as a puppy. A Springer puppy’s health often directly influences its size and health later in life.

Ideal Diet for Springer Spaniels

The most effective way to make your Springer grow is to feed a healthy diet. Good nutrition contributes to the overall health of your Springer Spaniel. 

Feed your Springer Spaniel balanced and nutritionally complete foods. If your Springer needs more calories, be sure those calories are coming from healthy foods instead of treats. 

Pet Parent Tip: How much your Springer Spaniel eats depends on their size, age, gender, build, metabolism, and activity level. It’s better to follow a specific nutrition plan after discussing it with your vet.

Here are some tips to help your Springer Spaniel maintain a healthy weight:

  • Make sure you are giving them nutritionally complete food.
  • Avoid excessive snacks and treats.
  • Keep mealtimes to twice a day with controlled, measured, and limited portions.
  • Make sure that he/she is not stressed.
  • Consider foods rich in proteins as they will help to maintain muscle mass.
  • Include probiotics and plenty of amino acids in their diet.
  • Research your puppy’s specific breed to better understand its ideal size and growth rate.
  • Fresh, clean water should be available at all times.

Exercise for Springer Spaniel 

Regular exercise is a very important point that contributes to the overall health of your Springer Spaniel. Getting exercise will help your Springer Spaniels grow strong. If your dog is allowed to get bored and is not walked regularly, they can become destructive and start to display behavioral problems. 

Risks During Springer Spaniel Growth

Springer Spaniels are generally healthy dogs. However, they can be prone to certain health conditions: 

  • Springer Spaniels might suffer from various skin disorders. The typical signs include scaliness, greasiness, itching, and occasional hair loss.
  • Springer Spaniels are prone to ear infections because of their pendant ear flaps.
  • Some Springer Spaniels suffer from a variety of allergies, ranging from contact to food allergies.
  • The Springer Spaniel has a high incidence of hip dysplasia, an inherited cause of hindlimb lameness.
  • Springer Spaniels might suffer from Patellar luxation, where the knee joint slides in and out of place, causing pain.
  • Springer Spaniels suffer from multiple eye problems including Retinal Dysplasia, Entropion, and Progressive Retinal Atrophy (PRA).

At What Age Do Springer Spaniels Calm Down?

The temperament and personality of each Springer will vary. This makes it tough to define a set age when your Springer Spaniel will calm down from a hyper puppy to a more sedate adolescent dog. Like most dogs, Springer spaniels usually calm down between the ages of 2 to 3 years old. 

Originally bred as a working and retrieving dog, Springer Spaniels have tons of energy and stamina. Springer puppies are filled with that instinctual working drive. They can be very active and mischievous at times. This drive is not going to go away on its own. So, training and physical and mental stimulation is a must to keep your pup busy. They can be a handful if you are not prepared to deal with a Springer puppy.

Training and exercise will help calm their overly active behavior. Springers are always going to be hyperactive if not trained properly.
