Leonberger Growth Chart (Weight Chart & Size Chart)

The Leonberger is a lush-coated German giant. They have a sweet demeanor and calm patience, and they enjoy the company of the entire family. Yes, the Leonberger is a large and muscular dog, but he is also noted for his aristocratic grace and elegance. A male can stand over 31 inches tall and weigh the same as a full-grown human.

 Females are smaller but still have a lot of dogs. A medium-length waterproof coat, lush triangular ears, a bushy tail, and a black facemask that frames kindly dark-brown eyes are all breed characteristics. The lion-like mane around the neck and chest is a striking characteristic of the male's coat.

When Do Leonberger Stop Growing?

A Leonberger will reach a full size between the ages of 18 and 22 months, depending on how big they will eventually grow.

Obviously, the larger the dog, the longer it takes to reach his full size. Because females are slightly smaller than their male counterparts, they normally attain their final size before males.

You should also keep in mind that physical maturity is not the only form of development that your dog must go through. You should also consider his behavioral and mental growth, as these are as crucial.

Leonbergers often reach mental maturity at roughly 3 years of age if suitable training is provided. It is not uncommon for full-grown canines to exhibit puppy-like mannerisms.

When it comes to behavior, socializing your dog at a young age will put him light years ahead. Because Leonbergers are huge breeds, it is even more critical because they can cause more damage than a lesser breed.

How To Weigh Your Leonberger Puppy?

If you want to maintain track of your Leonberger's weight, you must first learn how to weigh him properly.

To begin, you should be able to weigh your Leonberger at home if he is a puppy or if you are just large enough to hold him. This can be accomplished with a standard bathroom scale.

To begin, weigh yourself and record the result. Then, while standing on the scale, pick up your dog and hold him. The difference in weights represents your dog's weight.

If your dog is too huge to carry, you can either invest in a dog scale, which can cost upwards of $100, or contact your veterinarian. The majority of veterinarian offices will enable you to use their scale.

Unless there is a health problem, you can weigh an adult Leonberger once every six months. Once a week is sufficient for a puppy to ensure he is growing normally.

What Is A Leonberger’s Neck Size?

To determine the neck size of your dog, use a soft and flexible tape measure to determine the neck size of your dog where her collar naturally falls. Then, put two fingers between your dog's neck and the tape measure to ensure that the dog collar fits snugly but comfortably. Leonberger's average neck circumference is between 20 and 26 inches.

Factors That Affect Leonberger Puppy Growth 


When it comes to your Leonberger's growth, you should be aware that gender has a lot to do with the time and manner in which it is done.

Female Leonbergers, for example, reach full size at roughly 19 months, which is about three months earlier than males. They are, however, smaller and have less growing to do.

Hereditary factors also play a significant role in how they develop and their eventual size. When it comes to development, Leonbergers prefer to follow in their parent's footsteps.

Diet & Nutrition

Feed your Leonberger high-quality dog foods, either homemade or purchased commercially. Just make sure they get enough protein in their meals. They require this because, as huge dogs, they go through development spurts and gain muscle quickly. They will benefit from high-quality animal proteins.

You should keep an eye on their meals once they reach adulthood because being overweight might have a severe impact on their health.

Keep an eye on your dog's weight, especially if he or she is inactive. Also, make certain that they have access to clean, fresh water at all times.

Physical Activity & Health

Physical activity is especially crucial for a Leonberger who needs to bulk up. People who live in small apartments should think twice about getting a Leonberger as a pet unless they expect to spend the necessary time walking them every day.

They perform well in large yards where they can run around and play freely. They may feel claustrophobic in small apartments. They will be able to have strong bones and muscles if they exercise on a regular basis.

Common Questions about Leonberger

At What Age Is A Leonberger Fully Grown?

The average Leonberger will attain full adult size and frame between the ages of 18 and 22 months, depending on how huge they eventually grow. Naturally, the larger the Leonberger, the longer it takes for it to mature.

As a result, males of the breed often attain full-grown size maturity before females of the species.

How Long Are Leonbergers Pregnant?

Since conception in dogs lasts roughly 63 days, this can vary by several days. Despite the fact that this may appear to be a simple answer, conception is often difficult to pin down. It's possible for sperm and eggs to remain fertile for up to 48 hours after fertilization, thus the act of mating isn't a precise assessment of pregnancy. This makes it difficult to estimate the length of the pregnancy without the help of a vet.

The gestational period can be pinpointed much more precisely using hormone assays. To keep track of reproductive hormone levels, many breeders utilize vaginal smear exams and blood tests. They can use this information to figure out when is the best time to breed their buck, how long she will be pregnant, and when she might give birth.

How Many Puppies Do Leonbergers Have?

Puppies range from 6 to 14 in number. The size of Leo's litter varies tremendously. They are noted for having huge litters, with a record of 18 healthy puppies!

What Is The Life Expectancy Of Leonbergers?

The Leonberger, which has an average lifespan of roughly 7 years, is a fairly healthy breed. Despite this, it is known to suffer from illnesses such as cancer, hip dysplasia, and bloat (or stomach twisting), which can be avoided by eating twice a day rather than once a day.

How Much Does It Cost To Own A Leonberger?

A purebred Leonberger puppy costs between $1,500 and $2,000 when acquired from a dealer. The Leonberger dog price reduces significantly if you choose to adopt or rescue, with a rescue costing roughly $300 to $500 and an adoption costing around $150.

How To Help Your Leonberger Lose Weight If He Is Overweight 

As with humans, exercise is critical for your overweight dog's health. Increased movement helps your dog burn off excess energy (and calories consumed). Avoid panic! Exercising your pet does not have to include marathons or lengthy hikes. 

Regular walks and the opportunity to run and play safely off-leash. Even creating a stimulating indoor environment that encourages your dog to exercise on a regular basis can help. Bear in mind that different breeds require varying amounts of exercise, so visit your veterinarian, breeder, or your dog's breed standard for recommendations on recommended activity levels.

Distinguish Begging from Hunger

Distinguish Begging from Hunger
Distinguish Begging from Hunger

Begging is not necessarily motivated by a desire for more food; it is also used to gain attention. (And, by rewarding the behavior, you reinforce and encourage it to continue.) If your dog begs, do not automatically assume he is hungry. Trust your instincts and keep track of the date and time of your last meal. 

If your dog is prone to begging and you are prone to succumb to those puppy dog eyes, choose a high-protein meal with a fiber blend to help control your dog's hunger and voluntary food consumption. In this manner, you may feed your dog with the assurance that he will feel fuller and content for a longer period of time.

Restriction on treats and table scraps

Even when our dogs are not begging, many of us provide an excessive amount of treats and table scraps. Dogs are not required to share our food! Consider treats and scraps for your pet in the same way that you would candy for children to help you keep them in check. If you're going to utilize snacks for training, choose low-calorie, low-fat ones and keep the portions small. 

As an alternative, keep in mind that clickers are excellent for reinforcement… and they have no calories! After all, a few extra pounds can make a significant impact in the lives of dogs, which are significantly smaller than humans. (Even the colossal breeds!) Therefore, focus on a balanced diet and resist the temptation to “reward” them with extra.

Customize Your Dog's Diet

Not all weight-loss foods are created equal, which is why it's critical to match your dog's nutrition plan to their unique needs. Choose a brand that caters to your dog's unique needs, whether they be weight control, dietary sensitivities, or illnesses.

Conclusion on Leonberger Growth Chart 

Leonbergers shed a lot, so you'll need to spend money on grooming if you don't plan on doing it yourself.

They must be brushed every day, especially in parts of their body that are prone to matting. Because their coats are thick and full, many brushes are unable to reach their undercoat.

Ensure that you are properly grooming them, otherwise you may need to take them to a specialist.

It is critical that every Leonberger owner monitors their Leonberger's growth for proper growth by frequently weighing their Leonberger. 

Regular weight monitoring will allow you to discover any abnormal growth before it's too late. Earlier in this post, we explained how you can detect if your Leonberger is growing appropriately based on your Leonberger's weight history.
