Australian Shepherd exercise: mental work, heat and MDR1

An Australian Shepherd needs exercise that asks it to think as well as run. The breed was developed as a working stock dog, which the American Kennel Club describes as a lean, tough ranch dog perfected in California. Adults weigh 50 to 65 lb (23 to 29 kg) for males and 40 to 55 lb (18 to 25 kg) for females, with a life expectancy of 12 to 15 years. A dog built for a day's work on a ranch rarely settles on a short walk around the block.

What drives an Aussie's energy

Stock work is not a sprint. A herding dog moves at varied speeds for long periods, watches the animals and the handler, and makes constant small decisions. Pet Aussies keep that combination of stamina and attention to a person. Running loose in a field uses up some of the energy but leaves the working part of the brain idle, which is why many Aussies do best with activities that involve cues, rules and a job.

The signs of a dog that is under-occupied are familiar to anyone who has owned one: herding children, other pets or cars, nipping at heels, barking at movement, pacing, and inventing games like chewing furniture. More running alone does not always fix these. Adding training, problem-solving and structured tasks usually helps more than extra kilometers.

How much exercise a dog needs varies with age, fitness and individual drive, and there is no research-based number of minutes for the breed. A reasonable pattern for a healthy adult is some activity every day that leaves the dog relaxed afterwards, with at least one session that includes training or a task. A dog that is still restless in the evening needs more mental work, not just a longer walk.

Puppies and young dogs

Joint development is the main concern in the first year. The best evidence on exercise and hip dysplasia comes from larger breeds, but it points in a useful direction. In a Norwegian study that followed 501 puppies of four large breeds until hip screening, puppies that used stairs from birth to 3 months had a higher risk of hip dysplasia. Puppies that had off-leash exercise outdoors in that period had a lower risk. The authors recommended no stairs before 3 months and free exercise on soft ground in moderately rough terrain.

For an Aussie puppy that suggests:

• Self-paced play on grass or trails rather than forced, repetitive exercise such as long runs beside a bike or on pavement.
• Carrying young puppies up and down stairs, and avoiding jumps in and out of cars.
• Short training sessions several times a day. A puppy's attention span is short, and frequent small sessions teach more than one long one.
• No full-height agility jumps or weave-pole drilling until the vet confirms the dog has finished growing. Foundation work on the ground, such as targets, body awareness and handling cues, can start early.

Hip and elbow dysplasia are partly inherited. The Norwegian study found cases clustered within litters, so when choosing a puppy, ask for the parents' hip and elbow screening results as well as their MDR1 status (covered below).

Mental work

Training is exercise for an Aussie. Most take readily to learning, and a dog asked to solve problems every day is usually calmer than one that is only run.

• Obedience and tricks. Directional cues (left, right, back), retrieving named toys, and chains of behaviors give the dog something to think about. Two or three short sessions a day fit into most routines.
• Food as a task. Feed part of the daily ration from puzzle toys, a snuffle mat or scattered in the garden. The calories are the same; the time spent working for them is longer.
• Scent work. Hide treats or a scented object and teach the dog to search. Sniffing is tiring in a way that suits bad-weather days and dogs recovering from injury.
• New places. Different routes, surfaces and surroundings give the dog more to process than the same loop every day.
• Games with rules. Tug with a drop and a sit between rounds, or fetch with a wait before release, turns play into impulse-control practice.

Activities that suit the breed

Hiking and trail running

A fit adult Aussie makes a good hiking companion. Build distance gradually over weeks, as with any athlete, and check pads for cuts or wear after rough ground. Practice recall and a solid "leave it" before going off leash where there is wildlife or livestock. Wait until growth is complete before regular running on hard surfaces.

Heat is the main risk. Exercise, not hot cars, is the most common trigger. In UK veterinary records of dogs treated for heat-related illness, most cases followed exertion, and the median air temperature on the day was only 16.9 °C (62 °F). An Aussie will keep working long after it should stop. Carry water, take shaded breaks, exercise in the cooler part of the day in summer, and stop at once if the dog pants heavily, lags, stumbles or seems confused. A dog with those signs needs to be cooled with water and taken to a vet.

Agility

Agility combines speed, turns and handler cues, which suits the breed well. Classes also teach the handler, so the dog learns cues consistently. Start with ground-level foundation work and add jumps at full height only once growth is complete. Well-fitted equipment and non-slip surfaces reduce the risk of injury.

Herding and treibball

Herding instinct tests and lessons with trained instructors and suitable stock let an Aussie do the work it was bred for. Where livestock is not available, treibball is an alternative: the dog pushes large exercise balls into a goal on the handler's directions. It uses the same gathering and directional control without animals.

Swimming

Swimming gives hard cardiovascular work with little impact on joints, which makes it useful for dogs with joint problems and for older dogs. Not every Aussie takes to water. Introduce it in shallow, calm water, never force a reluctant dog, and use a dog life jacket in open water or strong currents. Rinse off chlorine or salt, and dry the ears afterwards.

Protecting the joints of an active dog

• Keep the dog lean. Ribs easy to feel and a visible waist. Extra weight adds load to every stride and jump.
• Warm up and cool down. A few minutes of brisk walking before hard work and an easy walk afterwards ease the transition.
• Vary the work. Alternate running, swimming, training and easy days rather than repeating one high-impact activity daily.
• Take lameness seriously. A dog that limps, is stiff after rest, or refuses jumps it used to take should see a vet rather than be rested and restarted repeatedly. Early diagnosis of a joint or soft-tissue injury changes what can be done.
• Discuss supplements and pain relief with the vet if joint disease is diagnosed, rather than starting them on your own.

Medicines and the MDR1 gene

Joint injuries, sports and travel all bring an active dog into contact with medicines, and for this breed that raises a genetic question.

Feeding a working dog

Calorie needs depend far more on workload than on breed. The Merck Veterinary Manual estimates the resting energy requirement as 70 times body weight in kilograms to the power 0.75, multiplied by 1.4 for an adult prone to weight gain, 1.6 for a neutered adult and 1.8 for an intact adult. For typical Aussie weights, rounded to the nearest 10 kcal:

These are maintenance figures for ordinary activity. A dog doing hours of herding, running or sport each day can need a good deal more, and individual dogs of the same weight can differ by 30% either way. Weigh the dog every two to four weeks when the workload changes and adjust the portion to keep ribs easy to feel.

• Food choice. A complete and balanced food suits most pet Aussies. Performance formulas with more fat and energy per cup make sense for dogs that genuinely work hard, and can make a less active dog fat.
• Meal timing. Avoid hard exercise straight after a large meal, and let the dog cool down and settle before feeding after exertion. Small training treats during work are fine, counted in the day's total.
• Treats and rewards. A training-heavy routine can add a lot of calories. Use part of the daily ration as rewards, or small low-calorie treats, and cut the meal on heavy-training days.
• Water. Offer water regularly during long sessions and always afterwards, more in warm weather.
