How Big Do Whippets Get? [Average Height, Weight & Size]

Whippets are renowned for their speed and slim build. While they were initially bred for racing, today, they are often kept as therapy dogs and pets. With a range of positive attributes, traits, and characteristics it is no wonder that they are such a popular choice. But how big are they and what size do they typically reach? I spent some time researching the breed standard and will be sharing my findings here today.

So, how big do whippets get? Whippets are classified as medium-sized dogs, typically reaching between 18-22 inches in height and weighing between 26-34 pounds. Male whippets are generally taller and heavier than female whippets, although both sexes will generally reach their full adult size by the time that they are 12-15 months old.

With the average whippet being no more than 35 pounds (except the rare exceptions), this is not a heavy dog by a long stretch.

In build they are lean and there is little of them.

It comes as no surprise that they are so speedy and that they have a long history of chasing rabbits, other similar-sized game are used in the racing ring.

As you can imagine, this purebred dog, therefore, does come with a high prey drive.

Thankfully, however, they are very loving, affectionate, and gentle with humans.

These dogs are naturally sociable and can get along quite well with other dogs; they can also be taught to be gentle with cats.

Let us now take a closer look at the average whippet size in much more detail.

We will be looking at their typical growth cycle, the age at which owners usually see their dogs stop growing, and if this breed can even get fat (they are usually so lean so is it even possible?)

You will also find out the average timeline it takes for them to reach mental maturity and start acting like an adult dog.

So, if you are thinking about adopting this breed, be sure to read this informative size guide to find out all the information you will likely need!

Average Whippet Height, Weight, And Size

Like most breeds of dogs, the average height, weight, and size depend largely on the sex of the dog.

On average, male whippets are between 19 to 22 inches in height; whereas females are between 18 to 21 inches in height. These measurements are taken at the shoulders.

Males have an average weight of 34 pounds, with females being slightly lighter at around 29 pounds.

At this height and weight, they are classified as a medium-sized breed which makes them suitable for both apartment and larger home living.

They do very well indoors, especially when their owners are close. They thrive on human companionship.

Heredity is another significant factor when it comes to the resulting size of an adult whippet, but there is a responsibility on the owner to ensure they reach their full potential.

Puppies must get the right nutrition from day one, getting all the nutrients that they need to grow appropriately. Either being overweight or underweight is not desirable.

The recommended daily feed for a whippet puppy is one/ one and a half cups of dry, high-quality dog food. This should be divided into two feedings and fed separately.

However, how much your whippet will eat will depend on their age, build, size, and activity levels.

A highly active dog will require more food than one that prefers spending most of its time lying down.

Exercise is essential for this breed, it keeps them remain fit and healthy, while also being sufficiently mentally stimulated.

This breed does require plenty of exercise and they are generally very high-energy dogs.

It is best to walk them multiple times per day as opposed to a longer, singular walk. A couple of 20-30 minute leashed walks a day is generally a good amount.

You must be mindful of the breed when keeping them on a leash, as they do have a high prey drive and a tendency to attempt to run off if they see the opportunity.

Equally, you will need to make sure that you have a high fence around your yard.

This will allow you to let your dog burn off some energy without the risk of escaping (which they will attempt to do if given the chance).

While exercise is very important to this breed to retain a healthy weight, you do need to be careful in the puppy stage.

They should not be over-exercised as this will put a lot of strain on their growing bones and joints.

Following the rule of five minutes of exercise per month of age is advised.

For example, a five-month-old whippet should not engage in more than 25 minutes of structured exercise a day.

Again, any running, hiking, or rigorous activity must also be monitored during this stage.

At What Age Are Whippets Fully Grown?

Whippets typically reach their full adult size by the time they are 12-14 months old. Generally, the larger the whippet ultimately becomes, the longer it takes for them to reach that size.

As males are larger, they tend to stop growing around the 14-month mark, whereas females tend to stop at the 12-month mark.

However, if a female is on the larger side, she may stop at 14 months.

Either way, most whippets grow rapidly between birth and eight months. This is why a high-quality, protein-rich diet is essential.

Nevertheless, the dog’s genetics will have a large influence on the resulting growth. It is for this reason that growth rates will vary slightly from one dog to the other.

Some lines grow faster than others and will reach their adult height by six months, whereas it can take some dogs for more than twelve months to reach their adult height.

Some whippets experience a short and fast growth spurt at different age intervals; such as at eight months, then again at ten months, and another spurt at twelve months.

After 12 months, it can take some whippets a few more months before their shoulders relax, and then you can determine their “real” height.

For the most part, a full-grown whippet is still small enough to sit comfortably on your lap, yet large enough to be a great running companion. In terms of size this dog is an all-rounder!

Let us now take a closer look at the respective growth timelines, for either sex.

Growth Of A Female Whippet

• At 3 months of age, a female whippet should weigh between 9.4 pounds and 12 pounds.
• Their size almost doubles by the time they are 6 months old, and their weight should be somewhere between 17 pounds and 22 pounds.
• Once they approach their first year, your female whippet should be around 22 pounds to 28 pounds.

3 Months	9.4	12
4 Months	13	15

• At 3 months of age, a typical male should weigh in the vicinity of 11 pounds to 13.5 pounds.
• Their size will also almost double by the time they reach 6 months old, and their weight should be somewhere between 20.5 pounds and 25.35 pounds.
• Once they approach their first year, your male whippet should be around 26 pounds to 32 pounds.

As you can see these are not huge dogs, but they do grow quickly.

When your whippet is fully grown, it’s essential to train them to maintain their peak physical condition.

They can run as fast as 35 mph and can jump over 6 feet when fully grown and healthy.

Many owners will often wonder why their whippet remains so ‘skinny’ even after months of growth.

The truth is, it’s perfectly normal for this breed to be lean; it’s what the breed naturally gravitates towards and is all part of their genetic makeup.

Nonetheless, you should follow the diet that your breeder advises for your puppy.

It will be a protein-rich nutritionally complete diet, but they can advise you on specific brands for this breed.

By sticking to this diet, and adjusting for your whippet at the various stages of development and growth, you can ensure they reach their adult potential.
