When Is a Whippet Fully Grown: Everything You Need to Know About the Size of This Dog

Whippets typically reach full maturity around 12 to 15 months, but this can also vary. They usually grow to be around 45 to 56 cm tall and 6.8 to 19 kg but can vary depending on gender. As with all dog breeds, Whippets require plenty of physical activity and proper nutrition to maintain a healthy lifestyle.

Whippet puppies are adorable and full of energy; since it takes a lot to reach full size, owners need to be patient – their Whippet will grow slower than a dog bred for racing or agility.

Consult your vet if you’re concerned about your Whippet’s weight or health. They will be able to provide you with advice and guidance on how to care for your Whippet as they reach adulthood.

The Growth of Whippets

As mentioned, Whippets reach a full-grown size between 12 to 15 months old. After that, their growth will slow down a bit. A Whippet’s height is determined by its weight – the heavier the Whippet, the taller it will be. When fully grown, a Whippet should weigh approximately 6.8 kg or more.

Female Whippets

Whippets are a dog breed commonly known for their speed and agility. Females grow faster than males throughout their lifetime, reaching full maturity earlier than males.

Male Whippets

Male Whippets reach a total size between 12 and 15 months old, though some may mature a little earlier or later. Males are typically larger than females at this age and usually weigh around 19 kg when fully grown.

There is no set rule for how big a Whippet will get – it depends on their diet and exercise habits. For example, a healthy Whippet should have a weight of around 6.8 to 19 kg when fully grown, although some may be slightly heavier or lighter due to variations in food intake or activity levels.

When Whippets Mentally Mature

Mental maturity depends on the Whippet in question and their overall development. For example, some Whippets may reach full maturity at around 12 to 36 months, while others may take a little longer. The key is to be patient and allow the Whippet to reach their full potential.

Signs that a Whippet is mentally mature include being comfortable with people and other animals, having good hygiene habits, and being fully potty trained. This process can take some time to play out, so be understanding and allow your Whippet to grow into their new role.

Signs That Your Whippet Is Growing Up

A Whippet’s lifespan is typically between 12 and 15 years. As your Whippet grows, it may change in color or shape. Some common signs that your Whippet is growing up include changes in behavior, such as becoming more independent or playful.

Less Destructive

As they age, Whippets start to act less aggressive toward other dogs or humans and will become less destructive. If you notice that their behavior has changed in any way – for example, if they start to growl or bark excessively – it might be time for them to leave your home.

On the whole, Whippets are usually quite gentle animals. Usually, they don’t cause much trouble apart from playing around from time to time when puppies are still growing and developing their personality.

Calm Energy

As a Whippet grows, it may lose its playful spirit. This might manifest in different ways – from becoming more severe and less active to having a more complex coat that changes color. They may also be more obedient and unlikely to get into mischief.

Factors That Affect Whippet Growth

As a small dog, the Whippet grows pretty quickly. Factors that affect Whippet’s growth include the environment, diet, and exercise. If you provide the right environment and nutrients, your Whippet will grow into a healthy, happy dog!

Genetics and Gender

There are definite gender and genetics-related differences when it comes to Whippet growth. Males typically grow taller and heavier than females, while some Whippets are born with longer legs or tails due to their genetics.


Diet and exercise also play a significant role in Whippet growth – providing them with the proper nutrition and adequate physical activity will help encourage healthy muscle development and height gain.

Whippets grow fast when they are provided with a high-quality diet. Make sure that the food you give your Whippet is nutritionally balanced and meets their nutritional needs, as underfeeding can lead to health problems down the line. Overfeeding will cause obesity and other health issues in your Whippet, do avoid doing so.

Physical Activity and Health

Whippets are one of the most active dog breeds and require plenty of physical activity to stay healthy. As a result, they grow fast and need regular exercise. If you cannot give your pet enough practice, it may not develop properly.

So, whether your Whippet is growing or already fully grown, keep them active and healthy by providing them with plenty of physical activity!

There are a few common health problems that Whippets can suffer from, such as hip dysplasia and bloat. Keeping your Whippet on a regular exercise schedule will help prevent these problems. What’s more, proper nutrition is essential for a Whippet’s long life – make sure to feed them high-quality food rich in proteins and healthy fats.

Neutering or Spaying

Anecdotal evidence suggests that some people have found that their Whippets grew slower after neutering or spaying. If you’re unsure whether to neuter or spay your Whippet, speak with your veterinarian first. Ultimately, it’s up to you to decide based on what’s best for him.
