Low

Great Pyrenees Social Traits
High
Same-sex aggression common, especially females. Keep opposite-sex pairs for peace.
Training
Australian Shepherd
- ** They thrive on positive reinforcement (clicker training). Harsh methods often backfire, causing the dog to shut down or become defensive.
Great Pyrenees
- Must convince them your request is worth their effort
- Harsh corrections cause shutdown or defensive behavior
- Focus on management over strict obedience
- Accept that recall will never be 100% reliable
Australian Shepherd Considerations
Aussies control movement by nipping at heels. In a family setting, they often attempt to "herd" running children, bicycles, or cars. This is not aggression, but a hardwired instinct that can be terrifying for toddlers and a liability for owners.
This breed has an intense need to be with their people. They do not tolerate isolation well. Leaving an Aussie alone for 8+ hours a day frequently leads to severe separation anxiety and destructive chewing.
Unlike the "love everyone" Golden Retriever, the Aussie is naturally reserved with strangers and protective of their territory. Without extensive socialization, this reserve can escalate into fear-based reactivity or aggression toward guests and strangers.
Great Pyrenees Considerations
The #1 complaint from suburban owners. Pyrs are genetically hardwired to patrol and bark at night - they were bred to ward off wolves and bears. This instinct cannot be trained out, only managed. Expect deep, booming barks at 2 AM when a leaf blows across the driveway.
Great Pyrenees do not believe in property lines. Without a secure 5-6 foot physical fence, they will expand their territory to include the entire neighborhood. They are notorious escape artists and will take the shock from invisible fences to pursue threats.
Adult Pyrs often exhibit severe aggression toward dogs of the same sex, particularly females. This usually manifests around social maturity (18-24 months). Opposite-sex pairs are generally recommended.
Pyrs are not dumb - they are independent. When called, they evaluate whether coming is more important than what they are currently doing (usually guarding). If they decide it isn't, they will ignore you completely.
Multi-Species Compatibility
| Species | Australian Shepherd | Great Pyrenees |
|---|---|---|
| With Cats | Caution - may chase | Excellent - bred to protect vulnerable animals, views cats as part of the flock to guard |
| Small Mammals | Supervision required | Good - low prey drive, protective instinct toward smaller animals in their family |
| Birds / Reptiles | Caution advised | Good with supervision - generally safe due to arrested predatory sequence |
Advanced Behavior
| Trait | Australian Shepherd | Great Pyrenees |
|---|---|---|
| Predatory Sequence Risk | Medium | Arrested |
| Biddability | High | Low |
| Noise Sensitivity | Low | Low |
| Territorial Barking | ||
| Same-Sex Aggression Onset | 18 months | 18 months |
Great Pyrenees: Predatory sequence arrested early - may chase predators to drive away but lack dissect/consume drive. Brilliant problem solvers but low 'working intelligence' (willingness to follow commands). Bred to work without humans so don't look to humans for answers.

Australian Shepherd: Australian Shepherd puppies require consistent training and patience.
Great Pyrenees: Pyr puppies are large, stubborn land sharks. A 6-month-old is the size of a German Shepherd but has the brain of a toddler. Critical socialization window 8-16 weeks - must expose to strangers, other dogs, and strange noises or natural guarding instinct can turn into fear-aggression.
