Australian Kelpies are medium-sized dogs. Males typically weigh between 35-55 pounds and stand about 16-20 inches tall at the shoulder, while females generally weigh around 30-50 pounds and stand about 15-19 inches tall.

Australian Kelpies are known for their intelligence, loyalty, and strong work ethic. They are energetic and eager to please, making them highly trainable. Kelpies are typically friendly and good with children but may exhibit a protective instinct towards their family. Due to their herding background, they can be less tolerant of non-family animals and may attempt to herd them.

The breed has a short to medium-length, weather-resistant double coat that is minimally maintenance. Kelpies can come in a variety of colors, including black, red, chocolate, fawn, blue, or tan, often with markings. Their coat sheds seasonally, so regular brushing helps maintain its health and manage shedding.

Kelpies thrive in active households that can provide ample exercise and mental stimulation. They do best in environments with space to run, such as homes with yards or farms where they can work. Kelpies do not fare well in sedentary lifestyles or apartment living, as they require regular activity to maintain their physical and mental health.

Australian Kelpies excel in various activities, including:

• Daily walks, runs, and play sessions
• Herding trials and training
• Participation in dog sports like agility and obedience
• Fetch and retrieving games
• Engaging in puzzle toys and tracking activities

Regular exercise and mental challenges are essential for keeping an Australian Kelpie happy and healthy. Their intelligence and energy mean they thrive best when given tasks to complete, whether in a working capacity or as part of interactive games with their families.
