Aussalier Dogs

You might have heard about the Aussalier, an increasingly popular hybrid dog that captures the hearts of pet lovers. This charming mix of a Cavalier King Charles Spaniel and an Australian Shepherd is known for its playful spirit and affectionate nature. If you’re considering adding a pup to your family, the Aussalier might just be the perfect blend of companionship and intelligence you’re looking for.

The Aussalier inherits some of the best traits from both parent breeds. From the Cavalier King Charles Spaniel side, they get their lapdog qualities, loving to cuddle and stay close to their humans. Meanwhile, the Australian Shepherd’s energy and smarts make Aussaliers quick learners who love to play. These qualities come together to create a dog that’s both fun-loving and eager to please.

As with any mixed designer breed, Aussaliers can vary in size, coat, and color. Typically, they are medium-sized dogs with a range of coat patterns that can include beautiful merle from their Australian Shepherd heritage. Their moderate size and adaptable nature make them suitable for various living situations, from apartments to houses with yards. Plus, they are known to be great with children, making them an excellent choice for a family pet.

Attributes of an Aussalier:

  • Size: Medium, typically weighing between 20 to 35 pounds.

Since the Aussalier isn’t a purebred dog, you won’t find them recognized by the American Kennel Club, but they’re gaining popularity as family pets. You’ll find them just as happy to curl up on the couch with you as they are to go for a run in the park. They’re also a great size for most homes, not too big and not too small.

This hybrid can show a wide variety of traits, so remember, every Aussalier is unique! You might get one that’s more laid-back like a Cavalier, or you could end up with a pup that’s got plenty of Aussie zest.

Origin and History of The Australian Shepherd King Charles Mix

The Aussalier is a charming and relatively new breed that combines the energy of the Australian Shepherd with the affectionate nature of the Cavalier King Charles Spaniel. Exploring this breed’s roots and development reveals a rich blend of its parent breeds’ heritage.

Breed Ancestry

The Aussalier blends two distinct lineage streams: the Australian Shepherd, known for its intellect and herding prowess, and the Cavalier King Charles Spaniel, famed for its loyalty and companionship qualities. Originally bred to serve on ranches and farms with their superior herding abilities, Australian Shepherds have a history linked to rural work, while Cavalier King Charles Spaniels have a more aristocratic lineage, serving as lap dogs for English nobility.

Breed History

The Aussalier was conceived as an attempt to create a dog with the Australian Shepherd’s utility and the King Charles Spaniel’s size and companionable disposition. This new breed aims to represent the best of both worlds: the Aussalier’s versatile nature makes it suitable for various owners, whether they live in a bustling city apartment or in a spacious countryside home.

American Canine Hybrid Club Acknowledgment

As of now, hybrid breeds like the Aussalier are gaining recognition, and the American Canine Hybrid Club is one body that acknowledges such breeds. Recognition from such organizations helps to establish the breed’s identity and encourages responsible breeding practices that ensure the health and well-being of these dogs. 

The Aussalier, while not as widely known as its parent breeds, is beginning to carve out its own niche in the canine world. As a mixed breed, they are not recognized by the American Kennel Club (AKC)

Physical Characteristics: What Does The Aussalier Look Like?

If you’re curious about Aussaliers, they’re a charming mix with distinctive looks that reflect their parent breeds — Cavalier King Charles Spaniel and the Australian Shepherd.

Size and Weight

Your Aussalier is a small to medium-sized pooch. Adult Aussaliers typically weigh between 9 to 16 kg (20 to 35 lbs) and stand at a height ranging from 30 to 51 cm (12 to 20 inches) at the shoulder.

Coat Types

The coat of an Aussalier can vary but often features a double coat, much like their Australian Shepherd parents. This gives them a fluffy and soft appearance. Coats can be straight, wavy, or curly and come in a variety of colors including black, brown, white, and tan.

Distinctive Features

Your Aussalier’s ears can be floppy like the Cavalier’s or more erect like the Shepherd’s, and they’ve got expressive eyes that could be brown, blue, or even one of each. Their overall appearance combines the sweet face of the Cavalier with the sturdy body of the Aussie.

How Much Does it Typically Cost to Purchase an Aussalier Puppy?

While prices can vary depending on the breeder, location, and lineage, you can expect to pay anywhere from $600 to $2,000 for an Aussalier puppy. Remember, the initial cost is just the beginning; you’ll need to budget for their ongoing care too!

Aussalier Temperament & Personality

The Aussalier is a crossbreed known for a warm and friendly temperament making it an excellent family pet. They often inherit the intelligence and herding instincts of an Australian Shepherd combined with the affectionate nature of a Cavalier King Charles Spaniel.

General Temperament

Aussaliers are typically amiable and adaptable. Their intelligence means they are quick learners and can be highly responsive to training. It’s important to remember that being part herding dog, they may occasionally show a tendency to herd people or objects, which reflects their innate energy and focus. They may also be more energetic and prone to barking than the normal King Charles Spaniel.

Interaction with Children and Pets

This breed is often affectionate and patient, making them a suitable companion for children. Their gentle disposition means they typically get along well with other pets if socialized properly from a young age. 

Aussaliers can make good watchdogs for  their family, which may result in barking to alert you of strangers or unusual events.

Energy Levels and Exercise Needs

An Aussalier’s energy level is generally high, so they require regular exercise to stay happy and healthy. They thrive on daily activities such as walks, games, or even agility training. Around 30 to 60 minutes of exercise a day is recommended to help manage their vigor. Regular exercise also helps mitigate potential health issues common in their parent breeds, ensuring your Aussalier stays in tip-top shape.

Health and Care

Taking care of your Aussalier’s health is a big part of being a pet owner. You’ll need to know about their common health issues, what to feed them, and how to keep their coat looking good.

Common Health Issues

Your Aussalier may face certain breed-specific health concerns. Hip dysplasia is one such inherited condition where the thigh bone doesn’t fit snugly into the hip joint. Watch out for signs like difficulty in standing or a strange gait. 

Heart murmurs  and heart disease also are an issue; these are caused by turbulent blood flow and may require veterinary attention. Retinal dysplasia is an eye problem you should be aware of, while congenital epilepsy is less common but still a concern for any potential Aussalier owner.

Remember that the merle coloring that can come from the Aussie dog can also cause deafness and eye issues.

Dietary Requirements

A balanced diet is crucial for your Aussalier’s overall health. They typically need a diet rich in proteins, fats, and carbohydrates, with the proper balance being key. Feed your Aussalier high-quality dog food that’s appropriate for their size and energy level. Also, always ensure fresh water is available.

Also make sure to choose a diet that is high in taurine, L-carnitine and MCT oil to help their hearts.

Grooming Necessities

Regular grooming keeps your Aussalier healthy and looking their best. Brushing a few times a week reduces shedding and keeps their coat shiny. This breed isn’t hypoallergenic, so frequent brushing can also help manage floating hair for anyone with allergies. Baths should be given every few months unless they get dirty outside. Moreover, dental care is important, so brush their teeth regularly to prevent gum disease.

How Long Does An Aussalier Live?

The Aussalier typically enjoys a life expectancy of around 12 to 15 years. Maintaining a proper diet, routine health checks, and regular maintenance are all key factors that can contribute to a long and healthy life for your Aussalier. Keep an eye on any eye problems or changes in behavior that might signal health issues and have your vet check them out right away.

Training and Socialization

When training your Aussalier, using consistent techniques and focusing on early socialization will set the stage for a well-behaved companion. Here’s how you can achieve that:

Training Techniques

Consistency is key. Start your Aussalier’s training early and stick to a regular schedule. Use positive reinforcement training methods, rewarding your dog with treats or praise for good behavior. This encourages learning and obedience without fear or avoidance. It’s also important to remember:

  • Use simple commands and repeat them frequently.
  • Keep training sessions short — a few minutes several times a day — to maintain your Aussalier’s attention.

Socialization Strategy

Your Aussalier should be introduced to a variety of environments, people, and other animals early in life. This early socialization helps prevent issues like barking at strangers or experiencing separation anxiety when you’re not around. Consider the following:

  1. Plan playdates with other dogs.
  2. Walk your Aussalier on a leash in different places like parks, busy streets, and quiet neighborhoods.
  3. Introduce your dog to new sounds and experiences in a safe and controlled way.

By focusing on these training and socialization strategies, you’ll help your Aussalier become a confident and well-adjusted member of your family.

Living with an Aussalier

When you bring an Aussalier into your home, it’s important to consider their need for both physical activity and a fitting environment. These dogs are social, energetic, and require ample playtime.

Suitable Environments

Your Aussalier will thrive in an environment where they have plenty of space to explore and play. While they can adapt to apartment living, it’s crucial to ensure they still get regular exercise to manage their energy levels. A home with a fenced yard would be ideal, but as long as you’re committed to daily outdoor activities, your Aussalier can be happy in smaller spaces too.

  • Housing with access to a yard: Preferred for play and exercise.
  • Apartments: Possible if daily exercise needs are met.

Exercise and Play

An Aussalier is a bundle of energy and requires regular daily walks and playtime to stay healthy and happy. Since they have working dog genetics, incorporating activities like agility exercises can be highly beneficial. These activities keep their minds active and bodies fit.

  • Daily Walks: At least 30 minutes to an hour.
  • Agility Training: Engages their mind and body.
  • Interactive Toys: Useful for indoor activity.

Daily Routines

Establishing a consistent daily routine is key for your Aussalier. This includes scheduled times for exercise, meals, and bathroom breaks. They are highly interactive with family members and enjoy being part of your daily life. As potential family pets, they’ll want to join in on home activities, so be prepared to have a little shadow following you around.

  • Morning: Start the day with a walk or play session.
  • Evening: Wind down with a walk and some quiet time.
  • Family Time: Ensure they feel included in your activities.

Choosing an Aussalier

When you’re considering bringing an Aussalier into your home, it’s important to find a responsible breeder and to understand what owning this breed entails. With their rising popularity and trainable nature, Aussaliers can be a joy to have, but remember, adoption is a significant decision.

Finding a Breeder

Start by researching:

  • Look for breeders who specialize in Aussaliers or have experience breeding the parent breeds: Cavalier King Charles Spaniels and Miniature Australian Shepherds.
  • Prioritize breeders who are reputable and can provide a history of the puppies’ parents and health clearances.

Questions to ask:

  • What is their breeding experience?
  • Can you meet the puppies’ parents?
  • What health screenings do they perform?

Considerations Before Adoption


  • Make sure you understand the costs involved, not just the purchase price. Aussaliers can be pricey due to their popularity.

Dog’s Nature:

  • Aussaliers can be vocal. Consider whether you’re prepared for a dog that might be more expressive with barking.

Shelters vs. Breeders:

  • You may find Aussaliers through rescue organizations or shelters. Adopting can be a more affordable option, and you could give a dog a second chance at a loving home.

Lifestyle Fit:

  • Consider if your lifestyle suits a trainable, active dog. Aussaliers need mental stimulation and exercise.


  • Ask breeders for tips on training and care specific to Aussaliers.
  • Prepare a list of questions to ensure you are fully informed before you decide.
