So, if you are set to be the lucky pet parent of a male Blue Heeler any time soon, expect the dog to reach a height of 18 to 21 inches by the time he reaches maturity. If it is a female, her max height will be 17 to 19 inches. In this article, I will share everything you need to know about Blue Heeler size and weight.

A Brief Introduction to the World of Blue Heelers

Blue Heelers, also known as Australian Cattle Dogs (ACD) or Queensland Heelers, are persistent, high-energy, and highly intelligent herding dogs. They have a compact, muscular build and are known for their loyal and alert nature. This breed is related to the famous Australian Dingo. But, Blue Heelers are typically slightly smaller than Dingoes. Here is a full-grown Dingo vs full-grown Blue Heeler size comparison chart:

FeatureDingoAustralian Blue Heeler
Height Male48 to 60 cm 18 to 24 inches46 to 51 cm 18 to 21 inches
Height Female48 to 60 cm 18 to 24 inches43 to 48 cm 17 to 19 inches
Weight Male23 to 32 kg 50 to 71 pounds18 to 20 kg 40 to 50 pounds
Weight Female23 to 32 kg 50 to 71 pounds15 to 19 kg 35 to 45 pounds

The height of these dogs is measured up to their shoulder blades. To measure your Blue Heeler’s height, make him/her stand straight on a flat surface. Use a measuring tape to measure the dog from the ground to the withers between his/her shoulder blades.

How Big Do Blue Heelers Get?

As you can see from the chart above, by adulthood, your Blue Heeler will weigh anywhere between 40 to 50 pounds (male) or 35 to 45 pounds (female). Here are two ways to predict a fully-grown Blue Heeler’s size and weight while he/she is still a baby:

  • Genetics: If you have purchased your Blue Heeler puppy via a breeder, reach out to them and inquire about the sizes of the previous litters. If your breeder knows the parents of your puppy, they can provide precise information on how big you can expect your puppy to get. DNA tests can also predict your Blue Heeler’s maximum size and weight.
  • Paw Size: Predicting a puppy’s “max size” by assessing the size of his/her paws is not an exact science. But, many vets can make this prediction. You can do it too. Just look at the paws of your puppy. Do they look oversized next to their body and legs? If yes, then your Blue Heeler still has a lot of growing to do.

A female Blue Heeler’s size will almost always be smaller compared to the males.

How Much Should A Blue Heeler Weight?

According to the American Kennel Club (AKC), the average weight of a blue heeler (fully grown) is anything between 35 to 50 pounds. Since these dogs weigh under 50 pounds and stand less than two feet tall (21 inches maximum), the Australian Blue Heeler is officiallyclassified as a “medium-sized” dog on the AKC spectrum of breeds.

When Do Cattle Dogs Stop Growing?

Your Blue Wheeler puppy will stop growing after 12 months. By their first birthday, your puppy will reach his/her maximum height. Your puppy will become a full-grown Blue Heeler by the time they become 18 to 24 months of age. That is when it will reach its maximum weight.

  • Male Blue Heeler Max Weight and Height: 50 pounds and 21 inches.
  • Female Blue Heeler Max Weight and Height: 45 pounds and 19 inches.

Since males are larger in size, they usually require two years to put on a healthy weight and finish growing.

Blue Heeler Growth Stages

To help you track and manage your Blue Heeler’s weight and height, I have created the following chart. This Blue Heeler size chart also explains how your dog’s space requirements will evolve with time:

AgeWeight (lbs.)Weight (kg)Height (inches)Space Requirements
3 months12 to 155 to 5-712 to 14Make sure the sleeping space (crate, playpen, or bed) is big enough for the puppy to lie down, stand up, and move around comfortably.   The puppy should be given access to toys and a small play zone by the time he/she is 3 months old.
4 months15 to 187-8 to 513 to 15Give the puppy access to different rooms in the house.
5 months20 to 249 to 1114 to 16Give the puppy access to outdoor spaces like yards or gardens.
6 months23 to 2610.5 to 1215 to 17Upgrade the sleeping space to a large-sized crate or playpen. Take the dog outdoors and give him/her space to run and play.
8 months26 to 3012 to 13.516 to 18Keep the same arrangements. Give your growing puppy blankets to him cozy at night.
10 months28 to 3313 to 1517 to 19Shift the puppy to his “permanent bed.” This can be a large-sized bed or a spacious, 30-square-inch playpen.
1 year30 to 3513.5-1618 to 20Now your dog has reached 100% of its maximum height. If your dog is comfortable in a big bed, there is no need to change anything. Just make sure that the dog sleeps in a noise-free spot.
2 years45 to 5020.5 to 22.520Give your fully grown Blue Heeler regular access to a yard; take them on runs as well. Keep their sleeping spot clean at all times.

As your Blue Heeler grows older and bigger, its space requirements will evolve. Use this chart to track your Australian cattle dog’s weight and height. In case you feel that your dog is overweight, take them for regular walks in the park. If you feel that your dog is underweight, take them to the vet and get a formal diagnosis.
