When Do West Highland White Terriers Stop Growing?

Many dog owners feel that when a puppy reaches the age of 12 months or one year, they are an adult, however, this is not always the case.

The truth is that different dog breeds mature at varying rates, depending on the amount of growth required. There is also a difference in maturity and adult size.

You can tell when your puppy has attained full development by looking for particular indicators. This could take the shape of modest developmental milestones, such as their canines reaching full size between the ages of 12 and 18 months.

Because the West Highland Terrier is a smaller breed, it will most likely attain full maturity between the ages of six and eight months. They will, however, continue to acquire weight until they are 12 months old.

What is the Standard West Highland White Terrier Size

The charming West Highland White Terrier (Westie, for short) has enchanted owners for over 300 years. It is smart, confident, and always amusing at play. This little bit tough earth dog is one of the most popular small terriers. 

The Westie's looks are enticing, standing 10 to 11 inches at the shoulder, with dark piercing eyes, a compact physique, and a carrot-shaped tail swinging with enthusiasm. Underneath the plush-toy façade, though, lies a classic working terrier of bravery and gameness. Westies are a breed of dog that was developed to hunt rats and other underground vermin. 

They are very strong and robust. The all-white double coat is stiff to the touch rather than soft and fluffy. Westies are alert and active, with the characteristics of a brave and self-sufficient ratting terrier: They don't need to be pampered, they'll chase after anything that moves, and their independence can make training difficult. Westies, on the other hand, will train well with time and patience due to their loyalty and keen intelligence.

How To Weigh Your West Highland White Terrier Puppy?

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

To begin, you should be able to weigh your West Highland White Terrier 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 weight 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 West Highland White Terrier once every six months. Once a week is sufficient for a puppy to ensure he is growing normally.

How big do they get?

Dogs are born in litter, with some being large and others being small, making it difficult to predict their final size. Having said that, there are a few strategies you can use to make an educated approximation.

One of the most important things you can do is look at your West Highland Terrier's parents. If you do not know the size of the parents, you should contact your breeder, who will most likely have this information.

Examine your dog's paws as well. Dogs must normally grow into their paws, which are larger than the rest of their bodies. So, if he has enormous paws, he still has a lot of growing to do.

DNA tests are also a possibility because they define your dog's ancestry and allow you to make a more precise assessment. You can also consult the weight chart included in this post.

Factors That Affect West Highland White Terrier Puppy Growth 


Center for Female West Highland Terriers Males grow less than females and usually do not grow much after the first season.

Diet & Nutrition

When given a high-quality diet, West Highland Terriers grow healthily. It makes no difference whether you buy professionally prepared food or cook it at home.

Physical Activity & Health

Westies love to run around and play. They also enjoy going for lengthy walks with their favorite people. However, be cautious because they have a tendency to chase after anything that moves, so keep an eye on them as you work.

Remember, they were bred to chase rodents, and this instinct remains in them.

Consider using a leash when walking them, and make sure your yard is fenced in. Exercising them will help them to have strong and healthy bones and muscles.

Common Questions about West Highland White Terrier

At What Age Is A West Highland White Terrier Fully Grown?

How Long Are West Highland White Terriers Pregnant?

A female Westie's gestation period is typically 58-68 days. In each litter, the bitch can have up to five Westie puppies. Because the puppies are born blind, they are completely reliant on their moms. Westies, as little white dogs, are vulnerable during pregnancy.

How Many Puppies Do West Highland White Terriers Have?

How To Help Your West Highland White Terrier 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

Dog food

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.
