When Do Vizslas Stop Growing? Their Growth Timeline

Vizslas are active, loyal dogs originally bred to hunt. Their boundless energy and affectionate nature have made them popular family pets. However, their rapid growth as puppies leaves many owners wondering – when do Vizslas stop growing?

These medium-sized, rust-colored dogs reach their full adult size between 1-2 years old. But their growth pace and pattern can vary depending on genetics, diet, exercise, and other factors. This article will walk through the key milestones in a Vizsla’s development from fluffy pup to mature dog.

Knowing what to expect as your Vizsla grows will help you provide proper care and nutrition. A healthy Vizsla will become your energetic companion for years to come. So read on for a complete guide to the Vizsla growth timeline and stages.

Typical Growth Stages for a Vizsla

Vizslas go through a rapid growth phase starting from the moment they’re born up until they reach adulthood. Here’s what to expect as your Vizsla progresses through different developmental stages:

  • 0 – 6 months: This is the most rapid stage of growth. Vizsla puppies can gain 2-3 pounds per week and 10-15 pounds per month during this time. They’ll reach 50-60% of their adult weight by 6 months old. Provide proper nutrition and monitor their weight gain.
  • 6 – 12 months: The growth rate starts slowing down. Your pup will gain about 2-3 pounds per month and achieve 80% of its full adult weight between 9-10 months old. Make sure not to overfeed during this stage.
  • 12 – 24 months: Most of the growth is complete by 12 months old. Your Vizsla will spend this time filling out, developing muscles, and reaching its final mature size. Continue providing excellent nutrition and regular exercise.

Vizslas are considered fully grown when their growth plates close and weight gain slows around age 2. But they’ll continue to gain muscle and enrich their lives through their teen and adult years with proper care.

When Do Vizslas Stop Growing?

By age 1, your Vizsla will have reached their approximate adult height and length. Typically, the most rapid growth occurs between birth and 6 months old. During this stage, it’s normal for a Vizsla puppy to gain 2-3 pounds per week and 10-15 pounds overall per month.

Their growth rate gradually slows between 6-12 months as they acquire 80% of their full weight.

Factors Affecting Size

Knowing the various factors that contribute to your Vizsla’s growth can help you manage their development effectively. Let’s look into some key elements that can impact your Vizsla’s size and growth rate.


The genetics of your Vizsla can play a significant role in determining their final size. Lines bred specifically for field work or agility tend to be leaner and smaller, whereas those bred for show or as family pets might be slightly larger. Consult with your breeder to get a better understanding of your pup’s genetic background.


Proper nutrition is critical for a growing Vizsla. Puppies require a balanced diet rich in protein, fats, and essential nutrients to support their rapid growth. It’s crucial to consult with your vet to determine the best diet plan that suits your pet’s specific needs.

Poor nutrition can lead to stunted growth or obesity, both of which can result in health issues down the line.


The decision to spay or neuter your Vizsla can also have implications on their growth. Spaying or neutering your dog can slow the closing of the growth plates, which might slightly affect their final adult size. Always consult your veterinarian to decide the best time to spay or neuter your Vizsla.


Regular and moderate exercise is vital for your Vizsla’s overall development, especially muscle growth. Exercise should be age-appropriate and gradually increased in intensity to avoid overexertion, which can harm developing joints and bones.

Consistent exercise will not only contribute to a healthy body but also a balanced temperament.

Understanding the Range of Full-Grown Sizes

Vizslas show a moderate variation in size, and it’s useful to understand this range to set your expectations. The dog’s gender, breeding line, and other factors can affect its adult size.

Gender Differences

  • Males: Typically, adult male Vizslas stand between 22 and 24 inches tall at the shoulder and weigh between 45 to 60 pounds.
  • Females: Female Vizslas are generally a bit smaller, with a height range of 21 to 23 inches and a weight range of 40 to 55 pounds.

Lineage Variations

Depending on their lineage, Vizslas can fall on different ends of the size spectrum:

  • Field Lines: These Vizslas are generally bred for hunting and agility. They tend to be on the smaller, leaner side of the scale to improve their speed and maneuverability in the field.
  • Show Lines: These are bred for appearance and conformation to breed standards. They often are on the larger side, with a more robust build.

Size by Purpose

Here’s a quick summary table to help you understand how Vizslas may differ in size based on their breeding line:

While the numbers can give you a general idea, each Vizsla is an individual. Other factors like diet, exercise, and health can also affect a Vizsla’s adult size.

Signs of Finished Growth

Recognizing the signs that your Vizsla has finished growing can provide peace of mind and indicate that they’ve transitioned from puppyhood to adulthood. Here are some key markers to look out for:

Slowing of Weight Gain

One of the most noticeable signs is a significant slow-down in weight gain. After 12 months, you may find that your Vizsla gains 1 pound or less per month. This is a strong indicator that they’ve reached their adult size in terms of weight.

Physical Development

Another sign that your Vizsla is done growing is the “filling out” of their physique. Their chest will broaden, and muscle tone will become more evident, particularly if they are engaged in regular, moderate exercise. This maturing of the body composition generally occurs around 18 to 24 months.

Growth Plate Closure

Veterinary x-rays can provide concrete evidence that your Vizsla has finished growing. Growth plates located at the ends of long bones will close between 12 to 18 months of age. Once these plates are fully closed, the bones will no longer grow in length, signaling the end of the vertical growth phase.

Wrapping It Up

So, when do Vizslas stop growing? Well, now you know it’s around the age of 1 to 2 years. But hey, your journey with your rust-colored, energetic friend is about so much more than just measuring height and weight.

It’s about watching them grow from a fluffy puppy into a full-fledged member of your family. Each stage has its own adorable quirks and little challenges, but armed with the right info, you’ll navigate it like a pro.

Keep an eye out for those telltale signs of finished growth, adjust their diet and exercise accordingly, and you’re well on your way to giving your Vizsla the happy, healthy life they deserve. Cheers to many exciting adventures and cozy cuddle sessions in the years to come with your fully-grown Vizsla!
